The 1932-3 Coach Renumbering Scheme

The 1932/3 Renumbering scheme grouped all coaching stock (pre- and post-grouping) into systematic number blocks according to coach type. Within the pre-group allocations, the numbering order was generally as follows LNWR (which carried the lowest numbers); MR; LYR; FR; CR; GSWR; HR (which carried the highest numbers). Generally speaking the LMS standard coaches were numbered consecutively upwards from the start of the block and the pre-group coaches were numbered backwards from the end of the block. The pre-group numbers were allocated in such a way that the complete pre-group block of coaches generally occupied the last and highest numbers in any series. This usually left a gap between the end of the LMS standard block and the start of the pre-group block which was available for new construction. In some cases the 1932 planners underestimated the size of the number blocks they would need and certain coaches overflowed into the other blocks - these are annotated below.
