Recreate the atmosphere of classic British railways with the MOC-229762 GWR 5700 Class Diorama Building Blocks Set. Designed and authorized by Mikey_Brickalloti, this 2,108-piece LesDiy configuration is inspired by the iconic Great Western Railway 5700 Class steam locomotive and presents it in a distinctive dark red color scheme inspired by London Transport livery.

The 5700 Class became one of the most recognizable British 0-6-0 pannier tank locomotives, serving both freight duties and shorter passenger routes. This display captures that heritage with the locomotive, two period-style coaches, track base, railway signaling details, and a richly developed interior.

The model has also been built and tested with real building elements by the designer. Following feedback, the driving rod design was updated in February 2026 to improve movement and reduce wheel binding.

From the Designer

Mikey_Brickalloti designed MOC-229762 as a tribute to the GWR 5700 Class, one of the most enduring sights of British railway history. Although the class was frequently used for freight work, it also operated passenger services on shorter and branch-line routes.

The model combines the locomotive with period coaches, detailed interiors, railway signals, and a dedicated display track. It has been physically built and tested, and the driving rod was later revised to improve its movement.

Best For

British railway enthusiasts, steam locomotive collectors, GWR fans, London Transport enthusiasts, railway diorama builders, vintage transportation collectors, and builders who enjoy detailed mechanical train models.
