Uses for the Triang Clerestories

by Russ Elliott


The Triang GWR non-corridor clerestory coaches can still be obtained secondhand at swapmeets and online auctions such as e-bay. Though not to any particular prototype, the bodies from these coaches provide a tempting subject for hacking about into more prototypical diagrams. The following notes by Russ Elliott provide a helping hand in that direction. On the following two pages, I supplement Russ's notes with some of my own Triang conversions.

These bodies are the 'old' Triang offerings, with moulded panelling, and should not be confused with the later Hornby longer corridor versions (see below), whose panelling is denoted merely by the printed lining. Two body types were produced; the Brake 3rd, and the 2nd.


Triang Brake 3rd clerestory

Triang Brake 3rd

Triang Brake 3rd body

  • The Triang Brake 3rd is numbered '2316'. The corresponding prototype number was carried by one of the vehicles in lot 972 (29/06/01), which was a 5-compartment brake 3rd, cler(3) to diagram D37 (nos 2312-2316). It was 50'0 3/4" long, and 8'6 3/4" wide. The D37 diagram was similar to the D24s, which had one compartment less.

  • The actual Triang body scales to a 46' 6" length and has one set of luggage doors less than the prototype D37. The Triang body is also only 8' wide, and is therefore of little use as a D37 (or a D24), both of which were 8'6 3/4" wide.

  • The body is suitable for stock that is 8' wide. The distance between the centres of the compartments in the Brake 3rd is 23.25mm = 5'10", and thus could be used for diagrams of 5'6" between partitions.

  • On this basis, the following diagrams appear to be feasible conversion projects: Clerestory Brake 3rd to diagram D8; Low-roofed Brake 3rds to diagrams D16 and D17, and similar Brake Composites to diagrams E40 or E50. Other diagrams might also be feasible with further hacking.


Triang all 2nd clerestory

Triang All 2nd

Triang 2nd body

  • The Triang 2nd body is numbered '5017', for which I cannot find any record. In general, this body has less potential for conversion than the Brake 3rd.

  • Again, the body is suitable for stock that is 8' wide. Distances between centrelines of compartments in the 2nd is 26mm = 6'6" (which equates to approximately 6'2" between partitions).

  • The nearest equivalent seems to be Clerestory 2nds to diagrams C19 (50' long) or C20 (51' long).
