Abstract
A railway carriage body comprises a shell structure formed from a base sub-assembly, a pair of side-and-roof sub-assemblies each of which constitute one side and part of the roof of the body, and a pair of end-wall units. The base and side-and-roof sub-assemblies when assembled together make up a series of transverse rectangular frames interconnected by longitudinal girders to which a sheet metal covering is fixed. Each frame includes a two-part lower transverse element forming part of the base sub-assembly, and a two-part upper transverse frame element the two component parts of which are included in respective ones of the side-and-roof sub-assemblies. The two frame parts making up each upper and lower transverse frame element are so fashioned as to permit them to be adjusted longitudinally of each other during assembly and prior to being rigidly connected together; as a result, the width of the carriage body can be set as required.
