Vereinigte Schweizerbahnen 2-6-0 Locomotives in Switzerland

Class VSB B 3/4 (Locobase 21108)

Data from SBB Locomotive Diagram LN 212648 found on the web at [], last accessed 15 December 2022. Works numbers were 639-640 in 1890; 656-658 in 1891; 740-742 in 1892; 1501-1502 in 1897.

These ten Moguls were among the first cross-compounds to go into service on a Swiss railway. Their compounding ratio fell on the low side while their evaporative heating surface ratios ranged toward the high side.

Five more fitted with larger cyilnders would round out the class (Locobase 21109). Three were retired in the 19'teens. The rest left the SBB's roster in 1920-1924.

Class VSB B 3/4 (Locobase 21109)

Data from SBB Locomotive Diagram LN 212648 found on the web at [], last accessed 15 December 2022. Works numbers were 1284-1285 in 1900, 1384-1386 in 1901.

The first ten Mogul cross-compound locomotives came on the VSB in small batches in the 1890s. The quintet shown here repeated much of the design, but provided better balance by increaseing both cylnder volume and firebox heating surface area. At the same time, tube heating surfface decreased. They were the last cross-compounds to operate on the VSB.

All five remained in service until 1924-1929.
