Here’s CN’s 1952 update to previous editions of the Triangle Route booklet. Typical of CN, this booklet is a step down from Canadian Pacific’s Through the Rockies: only 16 pages instead of 28 and filled with mostly black-and-white photos instead of all color. But the tour it advertises was definitely attractive.
By 1952, virtually all major U.S. railroads had streamlined and Dieselized their premiere trains. But CN and CP remained committed to steam and heavyweight passenger cars. It would be two more years before CN announced that it made a “record purchase” of streamlined passenger equipment that would only replace the heavyweights in mid-summer, 1954.
