I picked up Train Simulator Classic awhile back during a Humble Bundle sale and finally launched it today. I still have much to learn, but I enjoyed the tutorials. Looking forward to traveling the in the UK (I visited in 1995), so have been looking at all the DLC for England, Wales, and Scotland (my wallet will soon be VERY sore... .
Welcome aboard. If you're interested in British DLC have a look at the Great British Railway Journeys bundle- five routes of varying vintage and it must be said quality but all at least decent and 50% off in the sale at the moment though I don't know what it goes for in the US. I grabbed it for 60% off in the previous sale just to get the two routes I didn't already have and was perfectly happy about that.
