I have a dumb question regarding the arrangement of locomotives MUed together in a consist. If memory serves me right the first locomotive could either be arranged with long hood forward (better engineer protection in case of collision) or short hood forward (better forward visibility) depending on the railroad. My question is this, is there any methodology used to determine the arrangement of trailing units (long hood forward vs. short hood forward) or is it solely a function of convenience (don't turn the locomotive if you don't need to)? If there is a methodology, does it vary from road to road?
If I am only running two locomotives, I would probably run them back to back so that I could simply do a runaround to reverse direction and have the locomotives in the same arrangement. Not sure about three or more locomotives.
I have seen four-locomotive consists with the first unit short hood forward and the trailing units long hood forward. I have also seen four-locomotive consists with the first three lomoctives short hood forward and the last unit long hood forward. I guess this is the same basic arrangement as the first, but running in the opposite direction. I have seen other combinations as well, such as a
three-locomotive consist with the first and third locomotive running short hood forward and the middle locomotive running long hood forward. I was just wondering if various roads had standard policies regarding the arrangement of locomotives in consists.
Also, are there any rules of thumb regarding the order of locomotives in a consist when different types of units are used? Is the largest hp locomotive first, last, does it matter?
