DMU Engines

Leyland Albion 230hp Engine

The Leyland O.900 series range was built by the Albion Works in Scotstoun, Glasgow, a company that Leyland had bought in 1951. They would be badged as BUT engines but still commonly referred to as "Albions".

The engine was first used in the last deliveries of the Class 114s when the 680s were found to be underpowered for the longer steel vehicles in the power-trailer formation. The rest would then be retrofitted with the Albions.

The full list of the DMU types to be fitted with these engines:

• Class 114 Derby Heavyweights
• Class 115 Derby Suburban Quads
• Class 123 Swindon Inter-City
• Class 124 Swindon Trans-Pennines
• Class 128 GRC&W Parcel Cars

All had mechanical transmissions. The parcel car application gave 460hp for a single vehicle making it very powerful, this was to allow it to haul large tail loads.

An interesting summary of the engine development and rail use can be found in this post from the AEC Society forum.
