The London Midland and Scottish Railway (LMS) Hughes Crab or Horwich Mogul is a class of mixed traffic 2-6-0 steam locomotive built between 1926 and 1932. They are noted for their appearance with large highly-angled cylinders caused by restricted loading gauge. These locomotives were referred to as "Crabs", a term adopted due to the bizarre external shape of the standard engine.

Designed by George Hughes and built at the ex-L&YR works at Horwich and the ex-LNWR works at Crewe, they actually appeared after Hughes had retired and been replaced by Henry Fowler.

Initially numbered 13000–244, as standard locomotives they were given the lower numbers 2700–2944 in the LMS 1933 renumbering scheme. After being taken into British Railways stock an additional 40000 was added to their numbers, becoming 42700–944.
In 1931 five engines, 13118, 13122, 13124, 13125 and 13129 were fitted with Lentz valve gear. This was replaced on these engines in 1953 (which had now been renumbered 42818, 42822, 42824, 42825 and 42829) with Reidinger valve gear.
They were the basis for the LMS Stanier 2-6-0.
Three have survived, 13000/(4)2700, 13065/(4)2765 and 13159/(4)2859. The first-built locomotive, 2700 is part of the National Railway Collection and currently on static display. 42765 has been restored to working order on the East Lancs Railway, but 42859 is still in scrapyard condition, stored at RAF Binbrook in Lincolnshire.
Models exist in 00 gauge. An old, rather inaccurate model was produced by Lima, and an updated model has been produced by Bachmann. N gauge models are produced by Graham Farish.
