May I ask why you come to that conclusion? The gryolight was not effective
in the day time and east of Lake Louise anyway so it served no purpose as an
advertising gimmick. And why take it off when you would only have to put it
back on a few hours later anyway? If they would move it as required then it
obviously served some purpose or it would not have been there in the first
place. They may have taken it off and moved it to the locomotive at the
other end of the consist at turn around points, but I never saw them do
this. The fact I never saw them do this does not mean they didn't do it. If
they had a B unit or a Geep at the other end I would see them run the
consist around the wye as they always wanted a cab unit to lead on the
Canadian. So when you say "reasonable conclusion" you are in effect
guessing.

The use of the gyralight on the Toronto-Sudbury section of The Canadian
definitely had nothing to do with icicles hanging from tunnels. Because
their regular use was restricted to The Canadian, the only reasonable
conclusion is that they were an advertising gimmick.
