South Eastern & Chatham Railway P-class 27

P-Class No.27
No.27 at Sheffield Park in 1970 (Keith Salmon)

The P-class tank locomotives were, in design terms, an updated copy of the LBSCR Terriers. Eight of them were built in 1909/1910 and they were used initially to supplement and replace a series of steam railmotors which had been bought only a few years before, and which were proving underpowered. The P-class were only marginally more successful than the railmotors, and were themselves quickly overtaken by increasing traffic and heavier loads. From 1912, they were increasingly relegated to shunting duties, as shed and station pilots, a role for which, with the unsurpassed SECR-designed steam reverser, they were ideal. No.27 was re-allocated to Reading shed in July 1914.

No.27 saw war service, employed initially in Boulogne from April 1915, constructing sidings and returned across the channel after about 18 months with the ROD.

The members of the class were common at places such as Dover (27 appears to have spent much of its time there from 1945 onwards), and from 1938 onwards were the only locomotives allowed to shunt Kingston Wharf at Shoreham docks.

Coming to the Bluebell in 1961 as the infant Bluebell's third engine, for two years it carried the name "Primrose" (as seen in Ken Chown's photo, right, of it on the Newick Spur just south of Sheffield Park station, with Met. coach No.394). In 1963 it was repainted into full SECR passenger livery, and, with No.323, was a mainstay of the Bluebell's operational fleet for much of that decade, carrying the flag forward into the early 1970s. It has been said that it has only been in preservation days that the P-class have been able to demonstrate their true usefulness, with their greater water capacity compared to a Terrier proving quite an advantage.

Dismantled many years ago for overhaul, major work is required on the boiler, as well as some significant mechanical renewal. Fund raising is coordinated by Clive Emsley, Millfield, Manor Road, Upper Beeding, Steyning, W.Sussex BN44 3TJ
