Started a new game. First tutorial explained now to move the train - great. Next one, asks me to get in and Unlock Doors. Great, where's the button? Looked through settings, no keyboard binding for doors. Uninstalling because this is just silly.
It's T or the load/unload button in the HUD. There will be a manual in your Railworks directory or you can grab it from the TS Store page in Steam.
