I just purchased a K-Line Hudson steam engine and tender that has TMCC. When I run it in command mode it acts just like it is a conventional train. It will not keep a slow constant speed throughout the track. I have to increase it to a higher speed or it will slow down and struggle to make the curves. The engine speeds up around the curves and slows down on the straight parts of the track. I wanted to ask if someone knows what might be going wrong. I expect that in the command mode I should be able to slow the engine way down, and it should maintain that steady slow speed throughout the layout with no increase or decrease in speed.
