but alas only one powered unit doesn't have the nuts to pull the train i want
Yes I know. That's why I took your MR Power unit frame and changed the shell to the Olympian Hiawatha (OH)dummy A that is no longer a dummy A!
Now I have TWO linked OH power A's with, of course, 4 motors. I am now adding 2 more motors into the OH dummy B for a grand total of 6 (six) motors.
thanks again.
