I was on wikipedia binging british trains when i found the class 124 they sounded interesting to me i read up on them And i found out they might just fit in TSW They worked on a route that is in the game Northern Trans Pennine. They are a First gen DMU so IMO they are automatically more fun then standard locos and they have a nice and interesting little history to this line that i would love to see it in TSW2 in the future
