Bombay, Baroda & Central India 4-6-2 Locomotives in India

Class P (Locobase 20478)

Data from "Pacific Type Express Locomotives, Bombay, Baroda & Central India", Locomotive Magazine, Volume 30, No 380 (15 April 1924); and "New Express and Freight Locomotives, Bombay, Baroda & Central India", Railway Engineer, Volume 45, No 5 (May 1924), 168-179, 178.. Works numbers were 5366-5367 in 1924.

Among the biggest Indian express locomotives of the time, this pair was designed by the BB&IC's London-based consulting engineers Rendel, Palmer & Britton. They were about the same size as the IRS XC type and had the same cylinder volume. But the firebox was a bit smaller. Even so, that furnace designed to be large enough to burn India's low-grade coal economically.

Kitson turned out four big engines for the BB&CI, a pair of Mikados (Locobase 20998) and this pair of Pacifics. RE's report noted that a key goal was the "duplication of as many parts as possible" which the consultng engineers and the builder carried out "effectively" in "the boiler and its fittings, grate bars and ashpan, cab, cylinders valve motion, pistons and rods, crossheads and connecting rods, coupled wheel axlebox and hornblocks, springs and gear, and the trailing radial truck."

In addition to the large grate, the firebox featured a combustion chamber and 24 sq ft (2.23 sq m) of arch tubes. Steam was admitted to the cylinders through relatively large 11" (279 mm) piston valves. The trailing truck was a radial design with Cartazzi axleboxes linked through compensating beams with the trailing coupled axle's springs.

The tenders were also identical save the coal capacity, which amounted to 1 1/2 more long tons.
