What does "carriage full" mean on a Class 700?

[All Line Rover]

Currently on a 12-car Class 700 train which is standing room only (including in both of the "first class" areas). The passenger information display (PIS) says "carriage full" (red) for every carriage, as opposed to "standing room only" (orange). Why was the train announced as picking up passengers at East Croydon if it was completely "full"?

It's designed to be relative e.g. you'd pick a 'standing room only' carriage over a 'carriage full' carriage for reasons of comfort. It's not to be taken in the literal sense of the carriage being full, more designed to try and spread passengers evenly down the train.

So people could get off and change on to another train? Its quite the interchange is ECR

Probably because space for the boarding passengers would be created by the ones alighting.

Because not announcing it would confuse people - though it would make sense to automatically add the "this train has been reported full and standing; you may find you are unable to board" warning to the PIS.

Does it also show the overall fill levels of each train on the next train screens?

Certain GWR station CIS screens and audible announcements warn that a train is 'full and standing'. However, the last time I witnessed this (at Bath), the train arrived from Bristol with about 30% of seats occupied; about as many people boarded as alighted. Presumably some glitch in the system somewhere!

It's put on manually and it often is forgotten to take it back off again. A bit like overhead gantry messages on non-managed motorways.

Presumably not if the next train is formed of stock which isn't fitted with the load monitoring technology that the 700s have. It's useful tech to have though, might just take some getting used to!

How does this work? Is it a bit like the Pendolino weight sensors, which render the train immovable once the weight passes a certain threshold?

Indeed - the last time I saw this was at Betchworth, when the train was directed not to stop as a result! Never mind, there was another one an hour later.

What threshold is this? Is it far in excess of any crush-loading that might be expected? Rendering a train unusable because it is extremely full sounds like a step too far - if the doors cannot be closed, that should be sufficient, rather than a system that must be prone to failure (like any system) and thereby cause a cancellation.

Isn't it more that tilt is disabled in cl390s if they exceed a certain weight?

The class 700 has multiple methods used to count/weight passengers on board. The train is designed around a max weight that's beyond crush loading.

So will the train detect its threshold and prevent the unit from moving ?

The train itself will refuse to move if an axle is loaded above a certain weight.
