Here's a shot of FP7A 1417 in 1966: http://www.rr-fallenflags.org/cp/cp1417s.jpg
Here's #4068 in 1974: http://www.rr-fallenflags.org/cp/cp4068bdc.jpg
To me, except for the different paint, they look identical. Some of the 4000-series units were renumbered into the 1400s. Unfortunately, 1417 was wrecked in 1971. Here's another link with some roster information: http://www.trainweb.org/galt-stn/cproster/locomotive/1400s/1400a.htm
