Just for a bit of fun, I'm doing the opposite of another thread 'What is your favourite train?'
This will most likely end up revolving around bashing your most hated train, but try to keep it somewhat light hearted as at the end of the day, they're only trains.
I also only want ones that are still on the network as of writing, just so we can go out to point and laugh at anything we agree on
I'll start. Class 155. We all know the Class 153 is bad right? A single carriage that would be better as a bus than a train, and isn't PRM compliant. Bonus points if two are coupled together pointlessly when any 2 car unit would be better. Well, except the 155. The train so bad, the 153 was an improvement on it. Shockingly, some survive in revenue earning service.....
Your turn.
