Manufacturer description

The BR Class 29 is a type of Bo-Bo diesel-electric locomotive designed for both freight and passenger use. Although outwardly similar to the Class 22, they actually share no mechanical parts and in fact were a modified Class 21 with a replacement Paxman engine with improvements to power output.

These modifications were carried out between 1963 and 1965 mainly at the Polmadie Traction & Rolling Stock Depot in Glasgow. After the rebuild, the locomotives returned to Scottish duties until their withdrawal in 1971. No Class 29 locomotives survive preservation. Dapol have managed to provide for the Class 21 also in the tooling and this will be made concurrently with the Class 29.

The first EP’s have arrived and are currently being evaluated by the design team and a series of corrective measures will be made to each of the models to ensure that they are as true to the prototype as possible.

Prototype information

^* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

Dapol Class 21 D6121 BR Green locomotive, fitted with headcode discs and DCC sound, is supplied in OO gauge. The model is finished in a pristine BR green livery with the early crest and includes directional and interior lighting. All wheels are powered and the locomotive can negotiate a minimum radius of 2 inches. Couplings are NEM with a tension‑lock system.

The representation is of a British Railways Class 21 built by the North British Locomotive Co. between 1958 and 1960, for operation on British Railways. The manufacturer part number is 4D‑025‑001S and the period shown is the British Railways early crest era (1957‑1966). The wheel arrangement is Bo‑Bo.

Key model features include etched grilles, separately fitted handrails, finely detailed cast wheels and metal‑sprung buffers. A 5‑pole Super‑Creep motor with twin brass flywheels provides controlled pulling power and very slow running speed. The model is supplied with magnetic and traditional couplings and an accessory bag containing optional fitted components.

Technical specifications list the model as DCC fitted with sound, designed for two‑rail DCC track, and presented in a pristine finish. Its dimensions are 206 mm in length over buffers, 34 mm wide and 49 mm high.
