Are you the same Nigel Murphy that was the Head of Operations under British Rail ? I remember 071s on the Rosslare Dublin also. Being an old fart, I also remember the 141s before that, and the 001 A Class Metro Vicks before that too.
Nope. You are thinking of the 001 A Class Metro Vicks and the old 201 C Class Metro Vicks. 071s, 121s, 141s, 181s and the new 201s are all GM designed, built and powered.
