Welcome to Diagram3D

Diagram3D designs and produces kits for scale model railway vehicles. The kits are produced using innovative techniques and modern technology. The kits are laser cut in card, MDF or wood and can be assembled without soldering. The assembly instructions can be freely downloaded from this website. We don't mind sharing information and have a download section for interesting prototype information which has been gleaned from various sources.

Making models of historical railway vehicles can be frustrating. The prototypes often had complicated panels and details. Reliable historical information can be difficult to find. Producing a set of vehicles from scratch can be a daunting prospect.  Our intention is to reduce this frustration and save your valuable modelling time. Each of our kits will assemble into an accurate body shell which can then be used to produce a detailed model.

The results can be impressive. Visit our gallery for images of completed models and details of construction. Save your time by using our products.
