CLC Freight Locomotives - H16-44 H12-44, CNR Operating Manual 1966.

This long posting will complete the Canadian Locomotive Company product section

 of the consolidated CNR engineer operating manual of 1966.

Whether you see it as 'variety' or a 'lack of standarization' - this section of the manual is necessarily long to cover smaller freight (or dual purpose - some had steam generators) locomotives with B-B and A-1-A trucks; 1200hp and 1600hp prime movers; and Westinghouse, Fairbanks-Morse or General Electric electrical gear. For all this variety, fewer than 80 CNR locomotives are represented below.

The retro-popular H24-66 model - the Trainmaster - of which the CNR owned one, does not appear in this manual. The sole CNR copy was originally numbered 2900 in 1955 and left the CNR roster as 3000 in 1966. 

When it selected first-generation diesels, we can guess that the government-owned CNR had to show an interest in all the various Canadian manufacturers of locomotives - to spread the work around. As well, during dieselization, there may have been a benefit in trying a variety of models to see which worked best in Canadian conditions - particularly given the CNR's inherited light-track branch lines.

The following image comes from a Canadian Locomotive Company brochure from 1950.
It gives a rough representation of the lighter freight locomotives shown below.
The first locomotive type shown was not owned by the CNR.

This Cyclopedia overview of the 1600hp unit is followed below by its section from the CNR manual.

Built in 1955, the CLC-built H16-44 didn't have the affectation of rounded cab windows shown above. The high running board makes it closer in appearance to a typical Trainmaster than the earlier H16-44 styling.

When it may be helpful, I have enlarged and repeated illustrations from the CNR manual. There is a very wide range of image types and qualities in the manual. Some are rough and difficult to read, regardless of any 'treatment' I can give them. 

Here is the first section of the CNR manual ...

H12-44 (or H12-46 in Pinkepank's Second Diesel Spotter's Guide; 1973; Kalmbach) number 7608 is shown at Truro in May 1954. Pinkepank indicates these units - having an A-1-A truck - were only purchased in Canada. 

Originally numbered in the CNR 7600-7629 range, they were renumbered into the 1600-1629 range. The locomotive numbering of this era was dynamic as old steam motive power was removed from the roster and new diesel units were added.

Built in 1951-53, the last unit was retired by 1968.

Above: Notice the steam generator in the short hood and the CNR practice of operating long hood forward.

Reproducing these diagrams may not make them more aesthetically pleasing, but details may be clearer.

CLC Passenger Locomotives - CPA-16 CPB-16. CNR Operating Manual 1966.

According to one reference, the Canadian Locomotive Company passenger cab units lasted a little longer on the CNR (some until 1969) ... than the other opposed-piston-powered locomotives of Fairbanks-Morse design on that railway. 

Here is how they were covered in the CNR operating manual compilation of 1966.

The pages from the CNR operating manual do not have source captions. 

However, the images from other sources are labelled to show their origin.

There are no diagrams provided for the passenger units in the CNR book. Here is one found in the Locomotive Cyclopedia for 1950-1952. The F-M pages in the Cyclopedia are less lavish than those for the two largest diesel manufacturers. After trying to improve on the rough quality of the diagram below, I decided to leave it in its original state.

from: Locomotive Cyclopedia; 1950-1952; Simmons-Boardman.

Standard F-M nomenclature uses a suffix to denote the number of axles, so to them, the locomotive above is a CPA16-5

In the Cyclopedia, in a number of cases, you can also see Whyte-style classification used. So the unit above is an 0-4-6-0 ... or something.
In North American diesel nomenclature, it is a B-A1A.

I believe that the unusual third axle on this passenger unit is to support the weight of the steam generator equipment. While one could argue that this is evidence of fine engineering ... it might also be true that the opposed-piston design is already more unusual engineering than anyone desired to deal with. 

The two higher powered units of this series of locomotives (2000 hp and 2400 hp) used the same carbody and frame. F-M was selling the interchangeability of components with this design. When compared with units of the same power for freight service, the 2000 hp and 2400 hp units added about 20 tons of steam generator-related weight.

The 1600 hp version (the CNR unit) - detailed below, and also farther below - only adds 6 tons for passenger service. The A1A truck may have been seen as beneficial for use on some of the CNR's areas of lighter track.

The CNR images are repeated and enlarged so you can see more detail.

That marks the end of the CPA-16 coverage in the CNR manual.

The cover of a booklet detailing the CLC's steam locomotive history and wartime manufacturing, the Consolidation line of diesel-electrics, the CLC's export locomotives, the other heavy industry equipment manufactured by the CLC, and the significance of the plant to Canada and to Kingston ... featured the CNR-style unit on its cover. The illustration features an enormous front coupler housing.

My father had requested these locomotive data sheets from the CNR.
