Heljan enters TT:120 and announces two new models

Its first British TT 1:120 models will be the Gloucester RCW Class 122 diesel railcar and the Class 55 ‘Deltic’. The first to arrive will be the Class 122 ‘Bubble Car’ in Q1 2026, followed quickly by the ‘Deltic’ in Q2 2026.

Six Class 122 liveries and four classic Class 55 liveries are available to pre-order now.

Heljan is also working with Rails of Sheffield to deliver no fewer than six limited edition TT 1:120 ‘Deltics’ celebrating all of the surviving Class 55s in various post-BR guises, plus an exclusive BR Green Class 122 in early condition, ideal for use with BR steam locomotives and early diesels.

While the Class 55 will be an ideal companion for Mk. 1/Mk. 2d coaches, Pullman Cars, Gresley A3/A4 ‘Pacifics’ and HSTs already available, the Class 122 is designed to offer something new in this scale - a perfect starting point for TT newcomers. The Class 55 will also be the first Heljan TT:120 model to feature two ‘Power Pack’ capacitors to ensure smooth and uninterrupted performance when you need it. ‘Power Packs’ will be a standard feature on future TT 1:120 releases.
