About This Drawing

This is an attempt to create a realization of what trailer carriage number 163 looked like when in service. Please refer to the Realization Reference Booklet for a fuller explanation to the background leading to the creation of these drawings and sources used.

Realization Reference Booklet

This contains selected example photographs and other sources used to make decisions on points of detail that enabled this drawing to be created. The booklet should be consulted in connection with the Reference Numbers in blue blocks on this drawing.


AIR RESERVOIR TANKS: two metal loops that held the auxiliary air reservoir for the Westinghouse brake are shown here on the west side, below the fourth bay from the left; the tank and associated pipework have been omitted owing to insufficient detailed information being available, but see References 95, 96, 97 and 98.

BOGIES: these have been omitted as they would have obscured the underside detail. See Drawing 1 for bogie details.

BOLTS AND FIXINGS: these have been depicted where they were particularly structurally significant to understanding the construction methods used; others have been omitted as they would overwhelm the drawing.

COLOURS: the carriages were probably brown, though what shade is not known; the teak has been depicted in a mid brown and the metal panelling in a darker shade.

CONNECTING HOSES: hoses carried compressed air from the locomotive and across the gap between the carriages. The hoses fed metal pipework that generally passed along the full length of roof of the carriage. Junctions in the pipe took air to the brake equipment beneath the chassis, passing down the carriage ends in the space that remained beside an open doorway or down the side of the body, crossing the windows by being attached to the outside of a vertical window frame. Isolation valves and guard’s brake valves were fitted in various positions on carriage ends. All of these have been omitted in absence of any detailed images or clear evidence of the exact route that they followed, but see Reference 109.

DOORS: the lower runners appeared altered; the mechanism by which the top one worked has been interpreted from a photograph taken when at the Electric Railway Museum.

ELECTRICAL FEEDS: power was fed from the locomotive through bridging cables and cable conduit that linked all of the carriages. Lack of clear information has precluded some of the pipework being shown except where its position was confirmed by inspection.

FLOORING: the 1-inch layer of lito-silo (not visible from underneath) sat on top of a corrugated metal base.

LOWER OUTER PANELLING: the general arrangement drawing  notes these as 1/16-inch steel.

ROOF PANELLING: the general arrangement drawing notes this as 16SWG (Standard Wire Gauge).

ROOF STRAPS: as depicted here, these were tucked behind the bevel of the uppermost horizontal teak moulding.
