The first models from Dapol's latest batch of OO Gauge Class 21 and Class 29 diesel locomotives have arrived, with three variations now in stock covering both BR Two-Tone Green and BR Plain Green liveries.
These latest releases have also been enhanced for 2026, with upgraded detailing including tablet catchers appearing on the models for the first time where appropriate, plus optional snowploughs included for even greater flexibility when recreating particular locomotives and periods.
And this is only the beginning of the new batch. More liveries are still to come, alongside DCC Fitted and DCC Sound Fitted versions of the range, giving modellers plenty more Class 21 and Class 29 releases to look forward to. The first three are available in stock now at Rails of Sheffield, with the remaining versions available to pre-order ahead of their arrival.

ABOUT THE CLASS 21
A total of 58 Class 21 locomotives were produced by the North British Locomotive Co between 1958 and 1960. Externally similar to the Class 22, they actually shared no mechanical parts. Unfortunately, the class proved to be unsuccessful due to their unreliable licence-built MAN engines and between 1963-65, a total of 20 were rebuilt with new Paxman Ventura power units and became the Class 29. The remaining 38 Class 21s were withdrawn and scrapped by the end of 1968, with the 29s all being scrapped by 1971. None of the class survived into preservation.

ABOUT THE CLASS 29s
The Class 21 locomotives were built in the late 1950s and proved unreliable due to their MAN power units, built under license in the UK. To resolve this, British Railways chose to rebuild 20 of the locomotives with high-speed Paxman Ventura power units. The first trial rebuild took place in 1963 at Paxman's own works in Colchester. Nineteen more locomotives were converted between 1965 and 1967 at Glasgow or Inverurie works, before returning to service in Scotland. During the rebuild, each locomotive had a four-character headcode box added to each end. The Class 29s were immediately more reliable than the previous Class 21s, and the locomotives were put to work throughout the Scottish Lowlands on secondary passenger and light freight duties. Class 29s could also be seen on the famous West Highland line between Glasgow, Oban, Fort William and Mallaig and also occasionally as far north as Inverness. WIth the closure of some Scottish routes in the late 1960s, less locomotives were required to operate BR's Scottish Region. Despite their new reliablility, the locomotives were viewed as non-standard when compared to other classes and quickly withdrawn, with the last removed from service in late 1971. No Class 21s or 29s were preserved.
