T-TRAK inside corner module




T-TRAK modules come in fixed lengths, generally known as “singles”, “doubles” and “triples”.  Rather than being fitted with legs the modules sit on top of a table. Each module has adjustable feet allowing for any variation in table heights to be accounted for. To fit together into an oval (or other shapes), specially configured corners are needed.

An inside corner consists of a two track main-line with 90-degree curves of roughly 315mm & 348radius. (2 x Kato 20-111, 2x Kato 20-130 & 6x 20-121)

These kits use the Yorkshire Area Group/Australian standard of using the easy to obtain Phono connectors rather than the more difficult 'Anderson power poles'. Once assembled, this corner module baseboard is an irregular shape that fits in a 51cm square. A 3 part backscene/skyboard is supplied.

When assembled in a layout with standard size single, double, or triple modules, you may find there is a small gap due to the geometry. This is best filled with short bridging pieces from the 20-091 pack.

Designed and manufactured in Yorkshire.

Kit includes:

  • laser cut plywood boards which interlock to form the baseboard
  • threaded inserts and bolts to act as adjustable legs
  • nuts and bolts to attach backscene to base
  • phono plugs for electrical connection
  • 3d printed mounting plate for phono plugs
  • assembly instructions


  • Track pack with required unitrack -  2 x Kato 20-111, 2x Kato 20-130 & 6x Kato 20-121 (£16.40 inc VAT)
  • 2 x 24-818 Terminal unijoiners to provide a power feed for your track. (£7 inc VAT)

You will also need soldering iron, solder, wood glue, some scenic materials and imagination!



The logistics involved in preparing T-TRAK kits for postage mean that there is normally a 1-2 working day delay before despatch, sometimes more at busy times. If any item is show as 'Available on back-order' then there may be 5-10 days wait as some parts are en-route from a supplier, but you can still place an order. We will endeavour to keep you informed if there is any further delay.
