- The answer is more "why not" - almost all types of diesel locomotive
- can work together via control connections ("multiple-unit operation")
- that allow one engineer to operate several locomotives from one
- control stand.
-
- The direction the locomotive is pointed in doesn't particularly
- matter, except perhaps for the front unit, since the engines can
- work as hard in reverse as forward and places for turning them to
- get them poninted in the "right direction" are fairly rare these
- days.
-
- As to mixing the different types, this is simply a matter of
- convenience. A certain amount of "power" is needed to pull the
- train over the line and as many units as needed will be drawn
- from the available pool. In some cases certain types are
- assigned to certain trains or locations, in others flexibility
- rules.
