Data from the CN to 1953 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange collection. (Thanks to Chris Hohl for his 11 August 2017 email and spreadsheet supplying data and urging the inclusion of these enormous switchers and for his cite to more information in Charles R Foss, Evening Before the Diesel: A Pictorial History of Steam and First Generation Diesel Motive Power on the Grand Trunk Western Railroad, 1938-1961, 1st Edition (Boulder, CO: Pruett Publishing Co, l980), pp. 307-309.)

Derived from the large S-1f Mikado class (Locobase 9855), these transfer and switching locomotives underwent a couple of changes that converted road engines didn't usually receive. One was a significant shift of weight back from the empty front truck location to the drivers. The other involved replacing the standard Walschaert valve gear. S-1gs used Baker gear, S-1h conversions were fitted with Young gear.

Richard Leonard quotes a communication from Larry Bell on the 0-8-2's reputation: "In Durand, the 3500s were used on the 'top end jobs' almost exclusively. They were nice riding compared to the 0-8-0's because of the trailer wheel. However they could be a difficult engine for a fireman, before conversion, because they had a long firebox and did not have a stoker. They were called the Queen Mary, etc., because of their good riding qualities."

Engine and tender length given for those with tenders fitted with equalizers. Wheelbases for those with Symington trucks were 2" (50.8 mm) shorter.
