British Rail Class 126

The British Rail Class 126 diesel multiple unit was built by BR Swindon Works in 1959 and 1960 to work services from Glasgow to Ayrshire. It comprised 22 three-car sets and developed the earlier Swindon-built trainsets introduced in 1955 on the Edinburgh Waverley to Glasgow Queen Street route, which formed the first Inter City service operated by diesel units in Great Britain. The cars were of integral steel construction, with the bodywork acting as a stressed member, and each of the two power cars had two AEC 150 hp underfloor engines with mechanical transmission, giving a top speed of 70 mph. A number of buffet vehicles were included in the orders, and four vehicles survive in preservation.
