Wainwright B1

The Wainwright B1 4-4-0s were rebuilds of SER Stirling 4-4-0s and lasted a long time, a number of them seeing service with British Railways, although only one, 1446/31446 was given a BR number. 1217 was withdrawn in May 1950 so it is quite probable that the photograph of it further down the page is one of the last that were taken.

B1 Nº132 in SECR days. Just as interesting is the slotted post signal!

 
Shortly prior to his retirement from the SER at the end of 1898 James Stirling produced his "B Class" 4-4-0 express engine which was not only a far more successful design than anything he had produced previously but also exhibited marked differences of appearance above the footplate when compared with his previous engines. There was a larger boiler, a squarer cab affording the crew better weather protection and a polished brass casting over the safety valve seating. The tender now had its springs under the footplate and was fitted with a larger, 3,000 gal, water tank.

Two engines, 454 and 459, were fitted with Holden's oil burning system in 1901. Although this conversion was a success it was deemed to be too expensive to be adopted generally and the equipment was removed in 1904.

As excellent as these engines were, as time passed by they needed work and in 1910 Wainwright fitted new domed boilers which had a slightly smaller diameter than the Stirling boilers but had a 2 inch longer firebox. The boiler pressure was increased to 170psi and the heating surface increased. The modified locos were now classified as "B1 Class" and were to all intents and purposes identical to the "F1 Class" of 1903. The only way to tell them apart was from their tenders, the F1s having prominent outside springs. When Maunsell took over from Wainwright he increased the size of the smokeboxes and started to reduce the cylinders from 19" diameter to 18" diameter. Two of the class, however, kept their domeless Stirling boilers until withdrawal. In their final incantation they were remarkably handsome engines. A class of some 29 locomotives, the first twenty were built by Neilson Reid and the last 9 at Ashford. The first twenty locomotives started life with standard SER numberplates but with the addition of the maker's name, number and date. When changed for those of SECR pattern, these last details were left off.

In June 1919 Nº34 was fitted with Maunsell's top feed apparatus. Then in 1920 the boiler was transferred to Nº13 which then carried it for a couple of years before it was discarded. During WWII several of the class were turned into make-shift air raid shelters! 1101, 1440, 1450, 1453, 1455, 1457 and 1459 were positioned over pits, immobilised and surrounded with sand bags. It is not known if they were actually needed, nor if they were successful if they were.
