By
the time late March rolls around, I think most of us are really ready
to chase winter away. Back in the 1980s, CN still found it necessary to
maintain snow plowing equipment in London, Ontario as part of its
winter weather contingency plan. Busy main lines did not require
plowing, so if a plow train departed London yard, it was generally
headed north up the Exeter Subdivision. Such a train would usually
consist of the plow, two units, and the trailing van. The old F units,
with their streamlined car bodies, were ideally suited for this
service. Snow would not accumulate on their sides, and the
inward-opening doors meant the crews could easily exit in case the plow
got stuck in a drift. I think this is a big part of the reason the
9100s were assigned to London long after they disappeared from other
regions. GP9s and RS18s also performed on plow trains, although their
walkways often ended up plugged with snow. Their outward-opening doors
also must have periodically presented inconveniences. CN experimented
with roof-mounted appliances designed to minimize the amount of flying
snow that got sucked in to the rooftop fans. The accompanying photos
illustrate these snow shields, which were removable for normal
summertime service.
With
the abandonment of the south end of the Exeter Sub and the transfer of
the north end to the Goderich Exeter Railway, CN has exited the branch
line business in our area. Gone are the plows, and gone are the first
generation units that pushed them. However, Southwestern Ontario fans
can still chase winter plow trains on GEXR and Ontario Southland, so all
is not lost. As a bonus, OSR still operates F units on its plow
trains!

CN 4528 illustrates the snow shield treatment on a road switcher. Like
the other two photos, this shot was taken in the Rectory St shop area in
London, On. Both 4528 (Feb 15) and 9177 (Dec 21) were photographed in
1987. |

This rear view of CN 9177 provides a second look at the temporary covers
over the fans and a portion of the side grills. In case you were
curious, yes, the rear end of the F units was painted red in this
scheme! |
