Building an LNER Diagram 23 or 115 Full Third from MJT Parts:

As with most of the Gresley coaches there were a number of variations on the theme. These were the most common variety of Gresley teak coach and some survived into the 1960s. The MJT etched brass sides represent Diagram 23 - which was built between 1924 and 1927 - and Diagram 115 - built between 1928 and 1939. While outwardly similar the Diagram 115s were 3" wider than the Diagram 23s (9’3" as opposed to 9’0").

How to use this page:
All the necessary items are listed with the quantity for each initially set to 0. Change the quantities for each item as required for your coach building project and then at the foot of the page there is a button to add all the items you require to your shopping basket in one go. Please note that if you look at an item in more detail, the 'return to list' button on the detail page will take you back to the main MJT list, not this page, so use your browser's back button instead!

This page will allow you to select parts to make a ‘generic’ coach but if you wish your model to be historically accurate you would be well advised to seek details (photographs) of a particular vehicle. Considerable detail is given in:

    It is necessary to decide whether you would prefer to make a metal coach using MJT parts or use the etched sides to adorn a Hornby or Ian Kirk donor? If the latter go to Using the cosmetic sides with a Hornby or Kirk Donor

    Vehicles built before 1934 were equipped with Turnbuckle trussing while those built in 1934 and after had welded steel angle iron trussing. We can supply either type, so choose one or other of the following:

    Note: these packs contain brake detail (cylinders reservoirs etc.), dynamos and battery boxes. 2800T has the earlier pattern battery box while 2800A has the later pattern. Photographic evidence suggests that some vehicles with ‘angle iron’ trussing still carried the earlier pattern battery box. If using the angle iron trussing, the earlier pattern battery box is available as a separate item (see below) and can be substituted. Reference to a photograph of any specific vehicle is recommended.

    Underframe details are also available separately:
