Locomotives and Coaches

The Heritage Diesel Weekend will feature the GWR's unique collection of ex-British Railways heritage diesel locomotives and multiple units, operating an intensive service of trains plus a guest locomotive. Nine locomotives will be in use (subject to availability) travelling just over 1000 miles in the course of the 3 days.


Two of our locomotives undergoing extensive overhaul will form part of the exhibition inside the diesel shed at Toddington.


The intensive locomotive hauled service will be the main draw for enthusiasts highlights of which will be:


  • The visit of class 42 diesel hydraulic locomotive no.D832 ‘Onslaught’ from the East Lancashire Railway, a locomotive synonymous with Western Region express services.
  • Class 45 no.45149, a class long associated with the Honeybourne line in the 1960s and 1970s
  • English Electric class 37 locomotive D6948. A classic 1964 built diesel locomotive synonymous with South Wales and resplendent in immaculate green livery of the era when diesel and steam shared Britain's railways.


The GWR's 3 car class 117 Diesel Multiple Unit will be in use as a 4th hauled coaching stock set.


All our locomotives and railcars are owned by preservation groups or individuals and most have their own websites packed full of information on the locomotive's history, operation and latest news.
