Description
The side corridor gave access to two first and three third (later second) class compartments. The two diagrams were externally identical, but D171 had six seats per second class compartment whilst D172 had eight (no arm rests). Separate guard’s and luggage accommodation was provided, the latter carrying 1 ton. Later batches of both diagrams rode on Commomwealth bogies rather than the original B1 type.
