Manufacturer description

The model represents the final development of the 478 Derby/Sulzer Type 2s, which started with Class 24 in the late-1950s. This model will cover the D5238-99 and D7500-D7677 batches, built by Derby Works and Beyer, Peacock of Manchester between December 1963 and April 1967.

For the first time, models will also be offered as the famous Scottish Region ‘ETHEL’ (Electric Train Heating Ex-Locomotive) train heating units converted from Class 25/3s as a short-term solution prior to the delivery of Class 37/4s in 1985. These machines later found work with InterCity’s Charter Unit, lasting into the 1990s.

The new HELJAN Class 25/3 will feature our renowned high-performance chassis with all-wheel drive and all-wheel pick-up, illuminated headcode panels and marker lights, a 21-pin DCC decoder interface and provision for DCC sound.

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.

Heljan Class 25/3 model D7661 in early British Rail blue with small yellow panel sections. The locomotive is presented in OO gauge, numbered D7661, and finished to a pristine standard.

The kit is DCC ready with a 21‑pin socket, provides all‑wheel power pickup and directional lighting, and fits NEM chain couplings. Sprung buffers, illuminated headcode panels and marker lights are fitted, and the model incorporates a high‑performance chassis with all‑wheel drive.

The model portrays a British Rail Class 25 built between 1961 and 1967, representing the final development of the 478 Derby/Sulzer Type 2 series that began with Class 24 in the late 1950s. It covers the D5238‑99 and D7500‑D7677 batches built at Derby Works and Beyer, Peacock of Manchester from December 1963 to April 1967. The prototype served all regions on freight and passenger duties, achieving a maximum speed of 90 mph with a Bo‑Bo wheel arrangement.

Key features include DCC readiness, sprung buffers, chain and NEM couplings, detailed external and interior cab fittings, and provision for DCC sound via an optional decoder (S0174‑21). The model is 200 mm long, with a minimum curve radius of 438 mm (2nd radius).

Overall the Heljan Class 25/3 offers a faithful representation of the British Rail Blue (pre‑TOPS) locomotive, suitable for both static display and running in DCC‑controlled layouts.
