Class 378 EMU (and AP Enhancement Pack) review ~ Train Simulator

The London Overground Class 378 is a train that I've had in my TS collection for a long time (ever since it was released, come to think of it). I've had the idea to review this thing for over a year now, and while it's pretty mediocre in its default state, the train is significantly improved by the long-awaited Armstrong Powerhouse enhancement pack. But the EP is by no means flawless.
