Ex-LNW '18" Goods 2F 0-6-0 at Workington Locomotive Depot. No. 58396 (former LMS No. 28512) was one of many Webb 'Cauliflower' 2F 0-6-0s that before Nationalisation had dominated the passenger and freight traffic on the Cockermouth, Keswick & Penrith line; it was one of the last survivors of the 310 (built 1880 - 1902) when withdrawn in 9/53.

They were also known officially as the Express Goods 5ft 0in, and unofficially as the Crested Goods or Cauliflower Class, due to the application of the large LNWR crest on the middle splasher in the original livery.[2]

Design

The design featured a boiler pressed to 150 lbf/in2 (1.03 MPa) delivering saturated steam to two 18 by 20 in (457 by 508 mm) cylinders connected by Joy valve gear to the driving wheels.

The dimensions quoted in the class title could be misleading: several locomotives ran for a period with 17-or-17 1⁄2-inch (432 or 444 mm) cylinders; and the “5ft 0in” referred to the diameter of the wheel centres – measured of the tyres the diameter was 5 ft 2 1⁄2 in (1,588 mm).

A tank locomotive version was also produced as the LNWR 18in Tank Class 0-6-2T.

Service

Two locomotives were withdrawn before the 1923 Grouping, leaving 308 to pass to the London, Midland and Scottish Railway, who gave them power classification 2F, and renumbered them 8315–8624. The LMS later added them to the duplicate list by the addition of 20000 to their numbers to make room for additional LMS Stanier Class 8F locomotives.

Sixty-nine locomotives entered British Railways (BR) stock in 1948. BR allocated them the numbers 58362–58430, as adding 40000 to their numbers as was done with most ex-LMS locomotives would have taken them into the 6xxxx ex-LNER series. The last one was withdrawn from British Railways service in 1955. None has been preserved.
