4mm RTR locos

Another 48xx/14xx is perhaps not surprising, but a 517 is both unexpected and brave. Dapol has taken up the challenge. Further details here (for 517) and here (for 48xx/14xx).

Accurascale has announced a 57xx/8750 Pannier family, with a full range of variations and liveries. Expected, hopefully, Q1 2025. Further details.    (image courtesy Accurascale)

Accurascale has set a new RTR quality bar with its Manor

This list shows most GWR 4mm ready-to-run locos produced since the 1970s. The list is arranged by year of introduction on the GWR, and indicates current and previous manufacturers, although this has been simplified.

The list also indicates whether the models have been recently marketed, i.e. within the past 8 years or so, but please note manufacturers do upgrades to body and/or chassis designs from time to time. Discontinued models are often still available secondhand, or can be purchased at shows or found on ebay. NYA = not yet available.

Golden Age Models is planning to produce OO models of Star, Castle and King locos, plus Super Saloons, Cornish Riviera Centenary and some Collett large-window Sunshine coaches.
