12A Models’ 4mm/OO BR(S) Schools Tender Snowplough kits are now available to purchase from their web shop. An incredibly interesting and unusual item, these look great on any Southern Region layout set in the early diesel/electric period right up to the late 80s, early 90s.
A short history of the prototype
At the end of steam in the early 1960s on the British Railways system, the 40 members of Maunsell’s “V” class or “Schools” class locomotives were found to be redundant. Class 201 diesel electric multiple units had taken over much of their work on the Hastings route and withdrawals were complete by 1962.
During 1964, eight tenders were selected to be converted at Eastleigh in to independent snowploughs. Initially numbered in the Departmental Series “DS” numbering scheme, all were later renumbered with the addition of an “A” prefix from 1973 under the TOPS system. At this time they were also classified wagon code ZZV. They normally worked in pairs; the bread at either end of a Class 33 sandwich. Withdrawal came in the early 1990s.

The Model
Created from the ground up, this stunningly detailed kit is very easy to assemble with basic modelling skills and tools.
Unlike 12A’s other wagon kits, this DOES NOT come with wheels, but is compatible with a number of formats so the builder can choose. It can be built with 16mm spoked pinpoint wheels, 16mm plain axled spoked wheels, or 14mm spoked plain axled wheels. Parts are included for assembly with outside or inside frames and a shim is included if using 14mm wheels to bring the model up to the correct ride height.
The chassis frames are a single piece print, meaning you will not have to worry about building the chassis square and true; it already is!
