Toledo, St Louis & Western 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class H-4 (Locobase 16273)

Data from DeGolyer, Volume 24, p. 88. Works numbers were 20093-20094 in February 1902.

The Vanderbilt boiler enjoyed a (very) brief vogue at the turn of the century when several railroads were induced to try a couple. The boiler, which is most fully described in Locobase 4104, featured a stayless, corrugated firebox had a diameter of 57 3/8" (1,457 mm) and was 11 ft 11 in (3,327 mm) long, or 39" (990 mm) longer than the dimensions shown by Baldwin for the firebox itself. The extra length apparently constituted a combustion chamber created by dividing the single long cylinder into two unequal sections.

As with all Vanderbilt boiler engines, this pair was soon refitted with conventional boilers and fireboxes; see Locobase 6717.
