Comments on: In early 1966 EMD SD-40 demonstrators 7000 and 7001 paused at Toronto Yard with dynamometer car 62, CN steam generator car 15478 and business cars Mount Stephen and Glengarnock. These units were built on an SD-35 frame while production SD-40s were on the longer SD-45 frame leaving the ‘platforms’ on each end. CP must have been impressed as orders followed quickly.

Thanks. Just when you think you know stuff…

As a matter of interest 7000 was EMD 2/65 b/n 29876. 7001 was EMD 2/65 b/n 29875. Someone might be able to figure out which of the 434A to 434F engines they were.

EMD built a number of these in 1965 to demonstrate the 645 engine. 434A through 434F had the flared radiators. 434 G&H had the flush style radiators used on all production SD-40s. CP always numbered demonstrators in the 7000 series but I don’t know which two of the 434A to 434F units these were. See Diesel Spotter’s Guide page EMD-50.

Or are they SD45′s? I didn’t think any early SD40′s had flared radiators.
