Beyer, Peacock and Company
Most of their locomotives were  exported, especially the double ended Garrat articulated locomotives, which could go round tight curves.  Their boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they both have a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage.
