Toledo Terminal 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 31 (Locobase 5432)

Data from table in May 1916 issue of RME. See also http://www.pulhuj.com/Documents/TT_Steam_Listing_Master.pdf (last accessed 31 December 2010). Works numbers were 54391-54392 in October 1913; 55200 in March 1915; 55226 in August; 55627 in December; 56477-56478 in March 1918.

The Toledo Terminal was a belt line and these were relatively small Consolidations suitable for transfer service. Although produced over 5 years, the class's homogeneity extended into every dimension except for the tender capacity, which changed from 6,000 gallons and 15 tons to 7,500 gallons and 12 tons. (Locobase observes that the swapping of coal for water would have extended the locomotive's time in actual duty between replenishments. Was this change induced by higher water consumption than expected or better coal consumption?)

Locobase has a hunch that one of this class wound up on the Nacional de Mexico as the lone member of clase GR-38 with road number 1448.
