I had some weird things going on so I decided to get a fresh install. I copied and deleted the Railworks folder and did a cache verify and within seconds it said my game was ok??!! I just deleted it! So doing some exploring I found a folder called "downloading" in the SteamApps folder. In there was a copy of RW? So I assumed it was verifying this? Anyway I deleted it and emptied the downloading folder as there were some other things in there I have no idea what and on a re-verify, it now pulled it from the server. Running this new copy of TS2014 I had no Engine-Driver or Community or Workshop functions and the Store button was also greyed out. I did another verify and it pulled 418 more files down! Went back in and still no connections to engine driver and the others. I turned on Steam in game overlay and did another verify, got 200 + files this time. Still no communications. So I went to the Workshop from Steam, and subscribed to a scenario from there. It downloaded. I loaded up TS again and everything was working.
I don't know if any of this will help any one, but it fixed my quirks.
Addendum: I also discovered there was no TEMP or SOURCE folder under Railworks. Creating the Temp folder made the engine pictures show up in the Workshop.
