Looking for help on the fonts in this logo.
Thanks for the help.

Futura Condensed Bold  Suggérée par donshottype 

Custom, not fonts as such.
CN provides zoomable vector images of this logo, adopted in 1943, and its other logos over the years in a pdf at http://www.cn.ca/en/media/media-kit/trademark-licensing
Go to paragraph No. 2 and download the pdf called Historic Logos.

How about that. I was all over that site and never saw that. Thank you.

In 1943 Futura Condensed Bold had been around for over a decade and is very close to the logo lettering.
Would make an excellent substitute.
