[2] However, by the 1920s, there was a decline in the use of tramways, and the West Riding Automobile Company was formed to operate bus services from its bases in Wakefield and Castleford.

[2] In 1952, West Riding funded the construction of Wakefield bus station close to the Bull Ring at a cost of £60,000.

After local government reorganisation in 1974, the company worked with the West Yorkshire Passenger Transport Executive which organised services in the area.

As part of the privatisation of the National Bus Company, West Riding was sold to Caldaire Holdings.

The company was involved in the development of the Guy Wulfrunian from 1959 onwards, and purchased 126 of the 137 vehicles produced and acquired a further 6 second hand.
