Oudh & Rohilkhand 2-6-0 Locomotives in India

Class H - compound (Locobase 10777)

Data from Baldwin Locomotive Works, Record of Recent Construction ((1903), No. 32, p. 122-123; and DeGolyer, Volume 24, p. 173.. Works numbers were 19930-19932 in December 1901.

This set of Vauclain compounds completed the sixteen Moguls ordered by this Bengali railway during a British locomotive famine. On each of the smokebox, a single 9 3/4" (248 mm) balanced piston valve supplied steam to both the HP and LP cylinders. Both the firebox and dry pipe were made of copper and the tubes were solid drawn brass. Specifications stated that the "maximum permissible load" on any set of drivers should be 33,600 lb (15,241 kg).

Like the simples, this set of Hs went to the East India Railway in 1925. By that time, the locomotives had received a pair of 16" x 24"cylinders in place of the 4 with which they originally generated power. They thus were now essentially identical to the simple-expansion H class shown in Locobase 10776.

Class H - simple (Locobase 10776)

Data from Baldwin Locomotive Works, Record of Recent Construction ((1903), No. 32, p. 122-123; and DeGolyer, Volume 24, p. 173. Works numbers were 17445-17454 in February 1900, 19908-19910 in December 1901.

Locobase 10777 shows the three Vauclain compounds that completed the order for the O & R. When those locomotives were converted to simple-expansion, they joined the 13 in this class. All were taken into the Indian State Railways system and renumbered in a range, but not in order. Arranged according to their works numbers, the renumbering ran: 1876-

1877, 1863-1864, 1870, 1875, 1874, 1873, 1872, 1871, 1868, 1867, 1866. The three Vauclain compounds were renumbered 1865, 1862, 1869.
