Class F (Locobase 1075)

Data from TH&B - 3 1924 Locomotive Diagram book supplied in May 2005 by Allens Stanley from his extensive collection. Works numbers were 49650 in February 1911.

This latest of TH&B Ten-wheelers had 12" (305 mm) piston valves and was delivered with superheaters.

The 8 hauled passenger trains on the main line between Toronto and Buffalo, putting in almost 30 years of service before being sold for scrap in December 1939.

NB:The TH & B book does not give a separate superheater area; Locobase estimates the area based on very similar locomotives built with Vaughan-Horsey superheaters.

Class F1 (Locobase 11425)

Data from "TH&B Ten-Wheeler", Railway and Locomotive Engineering, Volume 20, No 6 (June 1907), p. 260. Works numbers were 40863 in February 1907 and 44269 in June 1908.

See Locobase 11427 for the superheated upgrade applied to #10. #9 apparently received no such update and was sold for scrap in 1928..

Class F1s (Locobase 11427)

Data from the 1924 TH & B Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Because TH&B did not give a separate superheater area, Locobase calculated it based on the very similar equipage found on the Central Vermont's I-7 class (Locobase 5397).

Locobase finds a mystery about one of the two locomotives shown as a pair of F1s in this diagram book. The 10 looks like a very straightforward updating of the saturated-boiler engine shown in Locobase 11425.

But #9, shown in Locobase 11426, was described as a freight engine with a smaller boiler, firebox, and drivers.

Class F2 (Locobase 1080)

Data from the 1924 TH & B Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also "Ten-Wheel Locomotive-Toronto, Hamilton & Buffalo Railway," Railway Age, Volume 38, (2 September 1904), p.p. 305-306. Works numbers were 29876-29878 produced at Montreal Locomotive Works, 29531 from Schenectady in 1904, 44268 from MLW in 1907, and 44395 in 1907 from Schenectady.

F-2a (28-29) weighed in at 143,000, F-2b (30) at 152,000.

25 and 27 were sold to a paper mill in Kapusaking, Ontario in 1926. 26 and 28 were sold in 1922 to the Temiskaming & Northern Ontario. According to the TH&B Railway Historical Society's roster ([]), 29 originally was sold to the Santa Fe, Raton & Des Moines Railroad as their #103, but refused by that line. After service on the TH&B, it was sold in October 1925 to the Atlantic, Quebec & Western and, after some consolidation, was carried on the Canadian National roster as their 118.

Class F2B (Locobase 11426)

Data from TH&B 3 - 1924 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange collection. See also "Locomotive Building," The Railroad Gazette, Vol XLIII, No 25 (20 December 1907), p 764. Works number was 44268 in June 1908.

Freight Ten-wheelers were increasingly rare on North American railroads by the time the TH&B ordered the 30 in 1907.

It served the TH&B for more than 25 years before being sold for scrap in November 1934.

Class F3 (Locobase 1078)

Data from Schenectady Locomotive Works, Illustrated Catalogue of Simple and Compound Locomotives (Philadelphia: J B Lippincott, 1897), pp. 98-99. Works numbers were 4252

4253 in November 1894.

Small Ten-wheelers acquired in 1895 by the TH&B's contractor Dominion Construction Company.

Both had second careers after being sold by the TH&B in 1919. Ex-20 was exported to Cuba to work for the San Juan Sugar company. Nichols Chemical Company of Nova Scotia bought the 21 and worked it for another two decades before scrapping it in 1939.
