Looks nice and a more realistic driving experience than DTG's previous simulators.
However the packaging of the London Underground Bakerloo Line as a core route hides the one thing that this publisher is incapable of getting right, namely correctly operating UK signalling. Buy any of the add on UK main line route packs and this problem stands out again. Those enthusiasts who want to drive UK routes in a realistic fashion relying on route knowledge and signal indications and dispensing with the HUD will find they can't because of the deficiencies in the implementation of the signalling.
If you want pretty visuals and decent train physics then this is not bad. If you want a reasonably realistic simulator of UK train driving operations then you need to look elsewhere because this isn't it.
