GP 7/9's hauling passenger trains?

[RobertInOntario]

Rob:
I've checked a few of my books and found only a few pictures of hood units on CN passenger trains.
One shot of a Geep (or SD) in Edmunston ona final VIA run -- number 3478 doesn't fit with roster.
Newfoundland seemed to be all hood units, but narrow gauge.
The Tempo trains ran with RS18s -- specially modified.
Pictures of 4017 as passenger-geared GP40. (one of two)
Many more pictures of hood units on CPR (or VIA/CPR) but predominantly RS18.

This is helpful. So, maybe on a few rare occasions, a CN GP 7/9 might have hauled a passenger train.

I've also borrowed a book called "VIA Rail" by Christopher C.N. Greenlaw from the library -- it contains a pic of some CP Geeps hauling an early VIA train. I thought if CP did it, CN might have as well!

Thanks for checking your books as well.
