Don't think it's raked enough for a high speed train like a 395, and Pendolino's don't have destination displays on the front, so I'll guess at it being a class 700 EMU?
I've never even seen one, bit modern for me.
Glad to see the return of this thread
I'll go for Class 153 given you can't just give 4 different answers in one go
Class 318?
73/9?
Class 150?
Class 156?
Open floor if correct
