Didn't really want to make a new thread for this, especially for my first one... so here goes.
Greater Anglia really need to change how they hand over rolling stock at stations. Once a service terminates, the PIS continue displaying the terminating station, which I have personally been confused by myself. You can usually predict it, if the departure board is showing one service, it will almost always be that one, but it's not always the case. Stock forming ECS movements should be set to Not In Service as soon as the train enters the station. Is there any good reason it isn't like this?
The other day I was at Ipswich and saw multiple people wander to platform 1, look puzzled at the train, then either board or sit on a bench to wait. Usually, it will depart and head to Lowestoft, but in this case it was heading to the Goods Junction to arrive into platform 2 and form a Cambridge service (I believe). I had suspected that it was out of service, but didn't tell anyone as I wasnt sure. Once the driver turned up, I let him know where the people were on the train (it was only 3 passengers), and informed anyone else who attempted to board. Unfortunately I was met with a rather rude stare as I explained it to two people boarding, requiring me to flag down the driver and let him know.
