I suggest the uk pack for £20. 60% off at the mo as they just released a new software 3 days ago called train sim world but that only comes with an american freighter/line at present. the one I've linked has most uk routes you can add all different train classes. Not up to the company's level of detail as their one, but good for concentration,route learning and theory never the less. Some routes can take 3 hours or more to drive so good concentration practice aswell.
This guy does awesome vids on signals and route learning

YouTube has been a great help for all things "learning to become a train driver" From Interview processes, questions, cab rides and theory. and also train simulator 2017 vids
