Thanks, HUTCH, for this neat video of those
unique locomotives at work in Canada. I was
also fascinated by the other two unusual locomotives --
the tgwo odd switcher-type locomotives, the CN 1419,
with "GR-412a" below her number on her cab, and
the CN 1422, with "PATRIMOINE FERROVIARE" on her
cab below "GR-412a". According to rrpicturearchives,
the 1422 was built in Jan., 1960, as CN 1076, a GMD1:

And the CN 1419 was built in Oct., 1959, as the CN 1052, also a GMD1:

And the "sweep", the subject of this fascinating video, the CN 7104,
was built in Jan., 1956, as the CN 1248, a SW1200RS,
and rebuilt at an unknown date by EMD as an SW1200RSm:

And it was great to actually see a caboose in action,
the CN 79531, which is a cupola caboose, too. Neat!

Switching work is very important. It is great for
those of us who are not railroaders to get a good
look at this important part of railroading.

That is a beautiful and classic suspension bridge
in the background at the 15:00 mark. Dunno where
that is, but as a bridge fan, I really love those
classic old bridges.
