The 'King Kong' thread posted recently got me thinking about smaller layouts where operators may not be able to run the full-scale Big Boys, Northerns, and the like.
What semi-scale (Rail King, Lionmaster, or similar) engines dominate your smaller layouts?
We had a RK Allegheny (photo here) awhile back that was quite large yet could handle the tighter curves. Also had a Lionmaster Class A that was super. No photos remain of it however.
