AT&N Consolidation Won't Run + No Whistle

Today I purchased and installed the AT&N Consolidation steam locomotive from STEAM.
However, when I place it in a scenario there's no throttle control showing up on the screen to operate it, and also the whistle will not blow. The bell, sander and other items do work.
Any idea of what has happened; this is a new bug for me to ever experience.
