As a southern steam enthusiast I was looking forward to this game.
It features a huge range of locos - Qs, Ns, Merchant Navy/West Country locos in original and rebuilt form, H15s, N15s and M7 tanks. It also has several early electric locomotives.
There are some pointless activities - one lasts 30 seconds! My main gripe is attention to detail. For example, on some locos when you look out of the side of the cab it tells you that the loco is left hand drive. Yet when you take the arial view the driver is on the right. Some of the cabs dont look quite right.
That aside though - it's a very good game and adds alot to train simulator
