Heljan samples all-new Class 42 Warship OO gauge model for British diesels

Heljan has reached the production-sample stage with its all-new OO gauge Class 42 Warship, and the latest models show this is more than a one-livery nostalgia job. The range is being built to cover the class from its 1958 introduction right through to preservation-era wear, including D821 in its distinctive DB livery from the late 1980s.

That matters because the Warship has always been a prototype with more than one identity. British Rail built 38 Class 42 locomotives at Swindon Works between 1958 and 1961, and the class was the Swindon-built, Maybach-powered B-B version of the Warship concept, shaped by German diesel-hydraulic practice and especially the DB V200 family. Heljan’s approach gives the model far more reach than the later, better-known four-character headcode-box appearance. Original-condition locomotives with the GWR-style train reporting number brackets are being modelled too, which is the sort of detail that instantly lifts a Warship project above a generic diesel release.

The company has also confirmed that the tooling is in its final stretch. Heljan says production is now complete and the models are expected to arrive in around three months. That follows a steady run-up to release, with a running engineering prototype shown in May 2025 and decorated samples publicised in November 2025 before the project reached production samples in June 2026.

For Warship fans, the long gap in the market is part of the appeal. Heljan says there has not been a brand-new Class 42 for roughly 40 years, so this is being treated as a clean-sheet model rather than a tweak to old tooling. That opens the door to layouts set in the early Western Region diesel era, later BR years, and preservation settings without forcing operators to compromise on period details.

D821 Greyhound is the standout example of why that breadth matters. It entered service in 1960, remained in BR service until 1972, and is one of only two preserved Class 42s. It has been based at the Severn Valley Railway since 1991, so its inclusion in the range gives the model a direct link to the surviving class and to the preservation scene that keeps Warship interest alive.

The production samples suggest Heljan has kept the project pointed at serious prototype coverage, not just a single crowd-pleasing finish. For pre-order customers, that is the reassuring part: the tooling is advanced, the livery spread is broad, and the model is still aimed squarely at the class as it really existed.
