 By placing the driver beside the engine and using a wider, straight-sided body, seating capacity was increased from 34 passengers to 46 passengers.The open-top body continued to use perimeter seating on the upper deck, but the additional width allowed the use of transverse seating on the lower deck.The bodywork was typically built by LGOC, but Short Brothers, Brush and Strachans all built smaller numbers to the same standard design.
