Caption: Odd lash up. Not the first and not the last time first generation paired with second generation, nevertheless still odd - and makes you wonder what the diesel shop, motive power people were thinking at that time. So here in evidence is a 4731-4729-4037 lash up, two high horsepower MLW M636 units paired with a low horsepower GMD FP7-A, the only commonality being all units start with the number 4. Anyone know if 4037 was repainted CP Rail action red? At Agincourt, in a gloomy damp haze - why even bother with photography sort of - November 1978 day, tri x negative by S. Danko.

Have a look at:

4037 was one of the last F-units to ber repainted, if not the last. By June 1978 it was in action red, so the date of your shot may be off by a bit…
thank you for the comment, given mrdanno4050 advice the negative had to be exposed in November 1977 (vs. 1978).
Q: have you seen or do you know of any images with 4037 in CP Rail paint?

Actually, it was more common than one might think to see this type of lashup on westbounds to London. There were a few reasons for adding a 4 axle unit to two big ones.
Sometimes a unit was destined for set off enroute at Guelph Jct, or Woodstock. Covered wagons probably would not be used in this situation though.
The tonnage on the ruling grade hill at Campbellville was 5100 for two big units or three four axles (except pups).
If a train had over 5100, even if only a few hundred, an additonal unit was assigned.
The third reason was for a livestock setoff at Maus back in the Ayr pit west of Galt. Only 4 axles units were allowed on the 1 mile spur which is still there.
If one was called for a westbound to London and had two big units plus a small one…especailly if the tonnage was under 5100…it was a sure bet that livestock had to be lifted at Lmabton for Ayr setoff.
Someimes manifest freight other than livestock was lifted at Lambton sufficient to exceed the 5100 rating, and that was the reason for the extra power.
