The NBR B Class (LNER Class J35) is a class of 0-6-0 steam locomotive designed by William Paton Reid for freight work on the North British Railway. They were introduced in 1906 and had inside cylinders and Stephenson valve gear. The first eighteen locomotives had piston valves and the remainder had slide valves.
Classification
Seventy-six locomotives were built and these passed to the London and North Eastern Railway (LNER) in 1923. The LNER classified them as follows:{{cite web|url=http://www.lner.info/locos/J/j35.shtml |title=The Reid J35 (NBR Class B) 0-6-0 Locomotives |publisher=Lner.info |access-date=2012-02-27}}
- J35/1 Engines with piston valves
- J35/2 Engines with piston valves and short fireboxes
- J35/3 Engines with slide valves
The entire class was fitted with superheaters between 1923 and 1942 and re-classified from 1937 as follows:
- J35/4 Engines with superheaters and slide valves
- J35/5 Engines with superheaters and piston valves
Numbering
Seventy locomotives of classes J35/4 and J35/5 came into British Railways (BR) ownership at nationalisation in 1948 and were numbered as follows:Ian Allan ABC of British Railways Locomotives, 1948 edition, part 4, p.29
