TOPS Code/Class:	MHA (1)		Previous	Next
TOPS Category: ?This is my own (unofficial) means to categorise TOPS codes based on what they relate to and whether they are long (4 characters, i.e. including sub-codes) or short (3 characters)	SW - Short Code, Wagons	In selection ?This works on your last-used TOPS selection, including any filters and sort orders. Buttons will not show if the current TOPS code was not in your last selection, or if you are at the beginning or end of the data set.
TOPS GENKOC: ?The first character of a TOPS code is known as the GENKOC and indicates the general type of rolling stock (e.g. 1xx are DMUs).	M - Mineral Wagons (Excluding Hoppers)	Overall ?This works on the overall TOPS code list without any filtering or sorting applied.
TOPS BRAKTY: ?The third character of many TOPS codes is the BRAKTY, indicating the type of braking equipment fitted (e.g. A indicates air brakes).	A - Air brakes

Notes

Note added Tue 10/05/2022 by Thomas Young

Category: Classification/Coding
In about 1992 a number of SSA scrap wagons (ex POAs) were hired to British Coal Opencast, and used in Scotland, the North East and the Midlands. In August 1992, 40 SSA wagons were reallocated to a pool for use in South Wales opencast coal traffic. TOPS code MHA-A was issued for these wagons in early 1993 and at least one wagon (470111) was repainted with the MHA code in August 1993. It would appear that it was then decided to use new MEA conversions for coal traffic instead, and the recoding of SSAs to MHAs never officially took place. The MHA code was re-used a few years later for ballast wagons rebuilt from HAA hoppers.
