I have been re-reading some of my older magazines and thought I would ask a question or 2 for the diesel experts.
The design and shape of the 42200, 44200, 80 and 81 classes all look the same.
I am aware that some were GM and some were Alco powered.
What were the major differences and why were the 42200 used primarily in the south and 44200 in the north.
I also read that the power units from the 80's were being used to re-power some of the 44 class.
I thought that this was strange as the 80 would have been a younger loco than the 44 and it would have made more sense to re-power the more modern loco with excess 44 power units.
Another quick question, in just about all the multiple loco lash-ups there seems to be a 48 or 2 in there?
How can the power be used equally when you have eg 2 81's and 2 48's working together. Would not the smaller 6 cylinder units be struggling and getting a flogging?
