This may be CN specific, possibly local to eastern Canada, but I've been noticing a little quirk on many CN locomotives. The MU cables at the front of the lead units on many trains seen to be purposely tucked out of harms way behind the snowplow. I've never noticed this before, and am wondering if anyone else has noticed this on CN or another road?
First thought was that it was a winter thing to keep snow from packing on them and causing possible electrical problems or making it a pain in the butt to clear them. But from the photos I've observed this practice in, it doesn't seem to matter what time of year... and if the snowplow was packed with snow, the cables would be even harder to dig out anyways. It's not a recent thing either, I've looked at a photo from 1985 in Quebec of an HR412 (see below) with them tucked away... in May.
Anyways, anyone out there ever model this detail (well, practice) on their locomotives?
A few shots of this practice:
