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.
