Cabins

Bristol East Cabin - Click To EnlargeThe need for adequate cabin space cannot be too highly stressed; it is advantageous to build with a view to future needs rather than present requirements. Both these points were carefully borne in mind when the Bristol cabins were designed, and a happy balance between utility and artistic conception has been attained.

The West and Loco cabins have two stories and the East three, the plain exteriors of red brick in Flemish Bond being relieved by white stone lintels and sills, the parapet around the flat roof is finished with a plain white coping.

The top floors of the East and West boxes have metal-framed windows running the entire length and three quarters of the way along each side, which, with central bay windows, give maximum lighting and visibility.

The interior walls are buff glazed tile up to window sill level, the remainder being plastered and painted a light cream colour . The flooring is of polished oak slats invisibly nailed.

The top floors house the locking frames; the ground floors in the West and Loco cabins, the relays; while the middle floor of the East cabin houses the relays and the ground floor the cable terminations, store-room, linemen's room and the heating apparatus.

The locking frames are supported on two 10 inch by 6 inch longitudinal rolled steel joists spaced at 14 inch centres , the fixing-bolt holes being spaced along the two inside flanges, the space between forming part of the duct for wires from the relay room to the locking-frame terminal board.
