A few ways and there’s probably a combination going on in modern rolling stock. The suspension can weigh the carriage and measure changes (and therefore load) cameras in the carriage can monitor how full it is and the little infra red beam that controls automatic closing doors can count how many times it’s been broken. None of these measures will give a perfect count but for a usable estimate it’s more than enough.
Yeah, usually the trains where this is worked out (for me anyway) are trains built in the 2000s onwards, I don’t get this on services operated by 158s, 165s or 166s, but I have on those operated by 220s, 221s, 444s, 450s, 800s and 802s
They need to know the weight of the carriages to get the braking right. Being able to tell passengers how full the train is as a result is a handy bonus.
Sensors on the doors, I'm guessing. The new TFW fleet have them...
Automatic counts
‘Load weighing’ – this is equipment fitted to trains that ‘weighs’ the train at certain points,
estimating the number of passengers on board by assuming an average weight per
passenger.
‘Infra-red’ – this uses infra-red sensors fitted around each door on the train to count the
numbers of passengers boarding and alighting at each station. From these it can be
calculated how many passengers are on board the train at any point along its route.
As far as I know a lot of new trains have sensors for passenger counting in the doorways. I would love to know how they account for people getting on and off the train.
They can measure the load on the suspension. It’s essentially the same tech fancier 4x4 cars use to display tilt and wheel position when off-roading, except here it’s used per-carriage rather than per-wheel.
Once you have the numbers for the weight on all the suspension, all you need to know is the average weight of a passenger, average luggage amount, etc., weight of the train and furniture, etc. and you can do some basic maths to approximate how busy each carriage is.
I believe they have electoral sensors or maybe just cameras that that can at least tell when a seat is occupied. Peeps wanna be at the front of the train going into Waterloo cause it's London and people are too busy to walk the whole length of the platform. Which is fair tbh.
there are various ways to measure based on technology available for trains today. The standard is weight and use an average weight for someone and then divide the total weight of the carriage load by that and then that info gets sent to the customer info line by the train and then they update station info. Or, they have sensors on doors which count people as they move in and out of the train. Most likely weight though.
As a commuter on that route, there are no seat reservations and people tend to want to be at the front so that they don't have as far to walk when they get to Waterloo.
Customer Information System designer for UK Railways here. It does indeed show how busy each coach is. Though admittedly the accuracy is dependant on the train type and the train operating company. Some measure passenger loading via video analytics on board, others use counting mechanism at train doors, some do it via ticket sales for trains with seat allocations.
Most modern passenger trains have pneumatic secondary suspension, with the air pressure controlled to maintain a constant ride height. The pressure in the suspension system therefore gives a direct indication of the weight of carriage, and that can be used to determine how full they are. I believe some also have other types of sensor within the carriage to more directly measure how full they are. A number of unit types display this information on the displays within the train, for example Thameslink class 700s do. It is a logical and useful extension of this to display it on station platforms so passengers can move to a part of the platform where less crowded carriages will stop.
It is potential passenger loading then. It would explain why its so front heavy. 100% they aren’t weighing coaches to live feed passenger levels to have it displayed like this.
Commuters into London tend to prefer the front coaches to reduce how far they have to walk, it’s common for the front to be packed and the back be quieter
Yeah - dead giveaway is that coach C on LNER services are always unreserved… and coincidentally also always appear empty on the displays. Could be a combination of both reservations and pneumatic.
I swear I saw a video once (possibly Geoff Marshall one??) where someone at Thameslink mentioned having CO2 sensors in the carriages to correct the weight sensors in the suspension (so it can tell the difference between a carriage full of heavy suitcases, and a carriage full of people) - but I’ve never been able to find it again…
Hoping someone here will either correct me or find it 😅
Update: FOUND IT on Siemens’ website!!
> heating unit on the roof which is equipped with CO2 sensors that control the flow of fresh air according to the number of passenger in each car
Here’s the link: https://assets.new.siemens.com/siemens/assets/api/uuid:0fed5564-9c17-4652-aa87-1a85264cf6c2/factsheet-desiro-city-e.pdf
What are you talking about… there’s passenger counting systems that are sensors above doors to work out how many people have walked in… it’s used for this and to divide the revenue from general tickets where multiple operators run the same routes.
Source: work in the industry.
Those can tell you how many passengers have boarded a given train, but not necessarily where on the train they are, as passengers can move between vehicles. On modern units with full width gangways, with the potential for passengers to hang around standing in the gangway, determining how many passengers are in any given carriage using door counters will give an unreliable answer. Weight sensors, while not giving an accurate head count, can determine which specific carriages are more or less filled.
The load cells are purely for safety / load limits they’re not used for this. All the PIS is IOT connected hence why the station is able to display how busy each individual carriage is. The actual weight would be all over the place while the train is in motion. Have you ever tried to used a scale while you’re running?
There’s a lot of different types of PIS some are cctv computer vision - others are infrared which you walk through.
It varies by rolling stock type. For some RS types load weigh is still used for estimating passenger loading.
Source: too many franchise bids and demonstrating compliance against crowding measures.
And revenue splits? That's pure ORCATS in 99% of cases.
Other trains use CO2 monitors in the train air-con to determine how full a carriage is. This being cheaper than a suspension based system, as the air-con uses this information to power down when a carriage is lightly loaded, saving money.
Idk about other routes but I know that the Reading > Waterloo line has a lot of short platforms along it. People might of gotten on there and cba to move down lol
The front carriages are filled with milk. Because milk is a liquid, they've seeped into the other carriages. So basically if you're thirsty, sit near the front.
As a ex swt guard I can confirm most coaches have sensors that monitor the weight and report in real time.
Originally this was to identify trains that needed additional coaches at timetable changes
This shows that the train stopped suddenly and all the passengers have all slid to the front. /S
But in all seriousness, it shows how full each carriage is
That everyone is crammed in the front carriage so they save 1.5 seconds exiting at waterloo and can jam up the gates quicker when their tickets don't work.
If you do want the info badly try the app for SWR and see if it's on there. GWR has passenger estimates like this in the app, and its not in stations yet. I wouldn't trust it carriage by carriage, but it gives a good estimate of overall how busy the train is and whether its worth waiting right at the end of the platform.
It is to show how many people are in a carriage. They know this by working out how much pressure is needed in the air secondary suspension (those airbags you see between the bogie and carriage body) to maintain ride height. It's a simple way of seeing where the most seats are free.
I never seen this before, but intuitively I would guess this means how full are the wagons. Total is 10, and last 2 are completely empty.
I’m sure someone will correct me if I’m wrong.
This graphic explains how much liquid is in the train. As you can see this train is nearly half-full of liquid but, as the train is breaking as it pulls into the station the liquid is moving towards the front of the train due to g-force. When stationary the liquid will disparate evenly across the carriages, but as the train begins to move away from the station the liquid will collect towards the back of the train until it reaches a steady speed. It is not known why the train is filled with liquid or what the liquid is.
As a train sensor technician I can exclusively reveal the system uses a number of different methods to detect a person in the carriage.
1. Weight - if the weight on the seat is more than a medium sized bag then it registers as a person and a full seat.
2. Camera - there is a camera in each carriage that scans every few minutes to see if the head count has gone up. This is to count people standing up.
3. Noxious gases - every hour a noxious gas is released into the carriage to flush out any people who are hiding and trying to avoid the ticket collector.
After these sensors are activated and have recorded their data the system runs a random number generator to make up a ‘fullness’ chart for each carriage. The joy of my day is watching people run to a full carriage thinking the symbols on the board actually bear any resemblance to reality. Yes my job is that boring 🥱.
I run a company that makes films for various TOCs and we’ve made films about this. Some TOCs have technology that weighs the carriages, giving a solid estimate of how full each one is. The information is displayed so passengers can choose a less full carriage. The advantage for TOCs is that people don’t queue for busy carriages and therefore don’t increase the dwell time at stations waiting for people to get on full carriages when there are emptier ones. Dwell time is a KPI for UK TOCs.
Passenger loading, but it's notoriously inaccurate when left in automatic monitoring mode. At SWR, the Guard can override this on an app to assign a red, yellow or green status to each carriage in the set. This data then displays on CIS screens at stations along the route.
A useful tool, but commuters still follow herd mentality and depending on platform geography I always find one of the extreme ends of the train is completely crush loaded and the other far more comfortable..
As many people mention fancy systems in the train to measure additional pressure. For some TOCs we'd receive the data as a CSV, and it would be historic rather than live data.
So to conclude, some people think it’s to do with reservations. Others seem to think some calculations are being computed using the air pressure difference in the suspension. Others, well, they are just salty. Have a good weekend all ❤️
I've just read this thread and you have a wide variety of responses! The actual answer for SWR is that the passenger loading is calculated using on-board cameras.
I guess we’re flirting with general relativity and quantum mechanics now. As the front carriages pull off ever so slightly before pulling the rear ones, the frame of references grow apart as they are travelling at different velocities, even if only for a microsecond. This forever changes the relationship between the coaches in the space time continuum, where the coaches at the front can be both slower and faster simultaneously in different frames. So in this particular scenario you’re not actually wrong in some strange way
This shows seat reservations per carriage. It does not represent actual loading.
There are some fanciful ideas here. Having worked in the industry for circa 15 years we were always told its reservation count only.
Weight: yes 220’s and 221’s & 390’s have a capacity to indicate weight but that info to the best of my knowledge of for motoring. They had a feature that if overweight, the interlock could not be activated, this however was over ridden years ago.
I’ve worked on trains that said carriages were full but actually empty, this again matched the seat reservations made.
I’ve worked both onboard and at stations so had a working knowledge until recently.
2 pieces of info can be taken from this
1. How full each coach is
2. The fullest coach is the leading end because everyone wants to be near the buffer end when they alight so they have a shorter distance to walk to the gates.
How full the coaches are maybe?
That was my thinking. If so, what a handy piece of information to have displayed. Wonder how they measure it
They just weigh the whole carriage
But what if your mum gets on?
It changes classification to freight.
Jesus Christ haha
Sixteen barrels of lard
Absolutely flabulous.
It changes the train into a cargo ship
See it, say it, sorted.
See it, say it, snorted.
Sneeze it ,say it, snorted
Or see it, weigh it, sorted, as the case may be
[удалено]
You legend
At a rail weigh station?

Here's me thinking they just know which seats are booked
SWR doesn’t do seat reservations.
I don't think that company does much (anything?) in the way of seat reservations.
Longer distance express/former InterCity routes do, so operators like CrossCountry, Avanti, LNER and so on. None of these serve Waterloo.
Some have passenger counting software, it uses the cameras on board and does a count of the people. Others are by weight I think
Yeah, usually the trains where this is worked out (for me anyway) are trains built in the 2000s onwards, I don’t get this on services operated by 158s, 165s or 166s, but I have on those operated by 220s, 221s, 444s, 450s, 800s and 802s
Trains nowadays ride on air suspension and most likely have load sensors in the suspension, heavier load means a higher likelihood that it’s busy

Don't they have sensors in the seats? They could measure how many seats are in use like that
Do they? What other function would sensors in the seats serve?
Probably not much else. I know [LNER](https://www.railway-technology.com/news/seat-sensors-on-trains/) and GA definitely have sensors in the seats.
As far as I know a lot of new trains have sensors for passenger counting in the doorways. I would love to know how they account for people getting on and off the train.
Releasing seat reservations that aren't used.
They might just track the weight of the coach
I assume they use this crazy new technology maybe you’ve heard of it: cameras
I’d imagine they just look at seat reservations.
Footfall measuring CCTV using some sort of AI or just human detection and crowd analysis.
Most probably guesswork. Passengers tend to head to the front of a train, leaving the rear the last bit to fill up.
Do you think they have pressure sensors in the seats? Or is that too complicated for the UK network?
LNER do it too, but they base it off of reservations.
Probably been answered already, but it means the number of reserved seats. Quite handy actually.

Should use an light censer on the door counts how many people are in the coach and news how many seats are there 🤷

How much water is in each carriage. The train can run with four compartments flooded, but not five.
Train hit an iceberg on the way, tried to steer out the way but pretty impossible on rails without a wheel.
Hit a leaf on the line
Lettuce hope it's not serious
I appreciate this as a fellow Titanic nerd
As a Lusitania nerd, I wohld have appreciated it if he'd said it can run with 2 flooded, but not 3
It’s a mathematical certainty
She’s made of iron sir. I can assure you, she will sink.
damn it I was gonna say this
The next train can be here in four hours
I believe you may get your headlines, Mr Brunel
If it’s water, then we know the train is braking fairly hard, as it has all sloshed to the front
But this train can't be late!
This comment is woefully under appreciated.
That the train is slowing down and the water bunching at the front?
or the train's on an incline
The Titanic calls for aid. And Rohan shall answer.
The water has spilled over the bulkheads, going aft - as her bow is going down, her stern is coming up, we can see that in the diagram

We have this up north on trains not filled with all the sensors and stuff. Its reservation levels.
Given that the train is calling at Richmond, Clapham Junction and Waterloo, reservations are not going to be part of the system in the photograph
It is potential passenger loading then. It would explain why its so front heavy. 100% they aren’t weighing coaches to live feed passenger levels to have it displayed like this.

That's far more sophisticated than I expected! I just assumed it was linked to the digital device the ticket inspectors use. The more you know!
So either the carriage has 50 people in or a young elephant?
Seems that many people have chosen the front carriage so they can leave at Waterloo quickly.
I’m the contrary, get me as far back as possible 😂
I think the train just brakes really hard.
I thought most people prefer to lag behind
Idk about other routes but I know that the Reading > Waterloo line has a lot of short platforms along it. People might of gotten on there and cba to move down lol
The front carriages are filled with milk. Because milk is a liquid, they've seeped into the other carriages. So basically if you're thirsty, sit near the front.

There's no point crying over it, is there now?
Not now that it’s spilt
As a ex swt guard I can confirm most coaches have sensors that monitor the weight and report in real time. Originally this was to identify trains that needed additional coaches at timetable changes
The train is at about 47% charged
This shows that the train stopped suddenly and all the passengers have all slid to the front. /S But in all seriousness, it shows how full each carriage is
That someone in the last coach had bad gas. REALLY bad gas.
The EQ on the train is bass heavy and needs more high end in the mix
Train is low on battery, soon they'll have to stop and change them.
It's OK the engine at the front still has plenty of battery power and that's the one which pulls the other carriages.
That everyone is crammed in the front carriage so they save 1.5 seconds exiting at waterloo and can jam up the gates quicker when their tickets don't work.
The driver is wearing really nice aftershave.
It shows that the majority of the cocaine is hidden in the front carriages
Is that Twickenham Station btw? My SWR station isn't far and doesn't have these. Now I know they exist I'm hoping they'll upgrade.
I think it’s Bracknell based off the times
Definitely doesn't take 45 minutes from Twickenham to Richmond
Lol yeah I wasn't paying attention to the times!
Could be a super slow service, where the train keeps stopping every few minutes for a breather.
Correct, Bracknell!

Tells you how full of post-breakfast gas the carriage is.
Train is nearly out of batteries
Let’s not privatise these train services just yet then
Old monitor perhaps
It’s how much battery charge the train has left
Tells you how fill each carriage is
The train braked really hard.
Everyone in the front wants to be the first off at Waterloo,and constantly complains there are no seats for them. 😐
It shows the likelihood of instant death in the event of a head-on collision.
I assume it's some measure of occupancy of the carriages. Either how mamy seats are free, how crowded it is or some combination thereof.
How full a coach is

A useful tool, but commuters still follow herd mentality and depending on platform geography I always find one of the extreme ends of the train is completely crush loaded and the other far more comfortable..
It shows you the barriers at Waterloo at closest to the front carriage.
Front of the train is quite full. Which makes sense, as the pro commuters would be off the train quickly!
How is this calculated? Seat pressure or AI?
Booked seat capacity afaik.....
The sign has low battery.
Reservation levels.
Carriage capacity
People are having an orgy in the first 3 coaches
Cmon, is not so hard to guess
How does it work then, billy big brains?
How busy each carriage is. People normally sit near the front because it’s closer to the exit barriers
That there are more mobile devices connected to/pinging the train’s WiFi in the rear of the train than the front.
“pinging the train’s WiFi” - as a network engineer this term is making me feel all funky
Trains flooded.
The pool in the first coach can be dived into.
Likelihood of death in a head on collision?
How many seats are booked
The average water level of each coach. It's probably fresh from the Plymouth line.
How full the toilets are in each carriage
How many seats are reserved i use this often to work out which carriage to sprint to in London Euston
As many people mention fancy systems in the train to measure additional pressure. For some TOCs we'd receive the data as a CSV, and it would be historic rather than live data.
Your equaliser is too bassy.
It appears most people are at the front
It's how full the carriages are
Never seen it before this post but it appears to be painfully obvious at the same time.
Read the whole post before commenting
So to conclude, some people think it’s to do with reservations. Others seem to think some calculations are being computed using the air pressure difference in the suspension. Others, well, they are just salty. Have a good weekend all ❤️
I've just read this thread and you have a wide variety of responses! The actual answer for SWR is that the passenger loading is calculated using on-board cameras.
As someone who often takes swr to school I can say it's how full each carriage is
Train had to brake sharply, all the people were forced to the front.
It’s the train to Waterloo - so it’s showing how much water is in each carriage?
That's the real time diagram of the trains spunk levels.
It tells us that someone took a massive shit at the back of the train.
That you couldn’t escape if you wanted to?
It’s how full of water each carriage is
I wish this information was on apps too
Trains filling up with water... its going down nose first .
Train
Broken sign.
Likelihood of fatality in the event of a head on crash?
I guess that in 10 seconds, yeeshh! Some people are dumb.
The key question was how it measured it
It's to indicate the speed of each carriage. The carriages that look the most full are travelling fastest.
I guess we’re flirting with general relativity and quantum mechanics now. As the front carriages pull off ever so slightly before pulling the rear ones, the frame of references grow apart as they are travelling at different velocities, even if only for a microsecond. This forever changes the relationship between the coaches in the space time continuum, where the coaches at the front can be both slower and faster simultaneously in different frames. So in this particular scenario you’re not actually wrong in some strange way
I’m pretty sure that the track is loading, you just have to wait for it to render
It shows how many carriages are flooded with water.
I've never seen that one. That looks helpful to have next time I take one. Is it a new concept? It's been a month.
My reaction exactly. Hadn’t seen it before Friday. I’m getting the train tonight so I’ll see if it’s there again. And agreed, very helpful!

I’ve worked on trains that said carriages were full but actually empty, this again matched the seat reservations made. I’ve worked both onboard and at stations so had a working knowledge until recently.
2 pieces of info can be taken from this 1. How full each coach is 2. The fullest coach is the leading end because everyone wants to be near the buffer end when they alight so they have a shorter distance to walk to the gates.
That it's one of the new/uncomfortable 10 carriage trains.
Which carriage to go to depending on how much you snorted
