Canadian Railroads > MLW Monday

BCOL 701 heading into the siding at Dragon and meeting a southbound CN detour train.  701 would be leading timetable train #23 (VP symbol) and CN 5245 is displaying green flags for a following section operating on the same schedule. I might be wrong on the date of this image, thinking this was late September 1979.

Lots to see in that photo. The BCR locomotive was part of the small group built differently than the follow on M-630's, there's usually additional posts pointing out my limited knowledge of this, but the question is did the 701 to 704 group operate any differently than the follow on 705 to 722 locomotives?

The most obvious external difference being the double sized vented box behind the cab, oh and the number of the side of the cab.

I'm guessing a rerailer.

Also when delivered 701 to 704 had a white background and black numbers in the numberboards. This indicated they were locotrol masters. Cheers

701 - 704 were basically the same as the newer M630's  705-722.  701-704 had "air start" whereas 705-722 had electric start for the diesel motor. If I recall, the vent behind the cab door, near the deck walkway was quieter on 701-704 as compared to the other locos. Other than some difference externally all the locos were the same and operated the same.
The "device above the center axle was a re-railer or sometimes called a replacer. It was used for rerailing derailed wheels. There were two types. one used on the outside of the rail and the other inside the rail.

Doug would the re-railer hanging on the lead truck of the CN unit be a third type, one that could be used on both sides of the rail?

Yes, that is what we called a "butterfly" re-railer. It straddles the rail, BC Rail did not use that type, prone to breaking.
