TTC Diecast is an established model retailer based in Derby, they operate a retail shop in the city, online store and attend many rail & bus events around the UK.

Specializing in model railway & model buses they have become a leading UK online retailer who are well known to many model bus collectors for their extensive range of new & secondhand models.

Since 2010 they have commissioned or produced Code 3 models exclulsive to themselves.
The code 3 models were mainly produced to tie in with the Showbus & Alton Bus Rally and Buses Festival events between 2011 & 2018. Two reworks of a comissioned EFE Leyland National were issued in 2024

In the early 2010s they announced plans to produce a range of highly detailed resin models produced by Resin Specialists & Model 1, in the event only a small number of these models made it to production stage du to finances being diverted elsewhere, the list below only shows the models actually released, the other proposed models are listed in the Resin Model section, some of which were subsquently produced by Resin Specialists themselves.

TTC Diecast still has a good relationship with Resin Specialists, and has more recently produced an exclusive Manchester “Mancunian” Atlantean double deck bus model for TTC Diecast, the first pair of releases both sold out on pre-order, along with the next three releases due in 2026.

More recent commissioned models have included several dealer white vehicles from 80M, NMCL & Britbus, these being aimed at modellers wishing to apply their own liveries.
Several Rapido Leyland Fleetlines & Bedford OB coaches were also produced in 2021 & 2024 before Rapido Trains UK suspended development of further model buses.
