Prototype Era
Era 2 (1875 to 1923) Pre-grouping
The prototype coaches were constructed between 1914 and 1920 made of steel body sides with an absence of panelling but with bolection mouldings around the windows and frosted glass top light windows, sitting on Churchward 9’-0” bogies. They were designed to operate as a set comprising Left hand and right-hand Brake Thirds, 1 or 2-Thirds and left hand and right-hand Composites enabling all corridor windows to be displayed on the same side, commonly used for cross country and main line working between cities.

Dapol GWR Corridor Toplight Brake Third (right‑hand) 3766 is supplied as a 4‑wheel, 00‑gauge model (part number 4P‑021‑005) representing a pre‑grouping Great Western Railway coach built between 01 January 1914 and 31 December 1920.
The prototype coaches were of steel‑bodied construction without external paneling, featuring bolection mouldings around the windows and frosted glass toplight windows. They ran on Churchward 9‑foot bogies and were intended to operate in mixed sets of left‑hand and right‑hand Brake Thirds, 1‑ or 2‑Thirds and composite vehicles, allowing all corridor windows to face the same side for main‑line and cross‑country service.
The chassis includes die‑cast frames with two stamped metal compensation beams that provide electrical pick‑up for wheel bearings via stub axles. Two styles of under‑frame truss rods are offered, and the chassis is wholly die‑cast. Couplings are close‑coupled on a cam to negotiate R2 (438 mm) curves and incorporate NEM pockets for magnetic couplings; traditional NEM‑compatible couplings may also be fitted. Wheels are sized for 00 gauge (16.5 mm) with allowance for 18.2 mm gauge wheels, and axles measure 26 mm over their ends. Sprung metal buffers are fitted.
The body is supplied as separate ABS‑plastic side shells. Gap‑free corridor connections allow operation on R2 curves. Each passenger compartment includes a separately fitted luggage rack. Period‑appropriate roof ventilators, metal door and commode handles, and destination boards are provided separately for fitting. All coaches are equipped with interior lighting and a DCC decoder plug with a blanking plug.
