NEW SCALE, TWO NEW MODELS!

HELJAN TT CLASS 122 DIESEL RAILCAR - FIRST ENGINEERING SAMPLE

HELJAN LAUNCHES TT 1:120 RANGE WITH HIGH SPECIFICATION ‘DELTIC’ & CLASS 122 RAILCAR

HELJAN TT CLASS 55 DIESEL - FIRST ENGINEERING SAMPLE

HELJAN confirms major investment in British TT 1:120 with TWO new high quality models of popular prototypes that will boost the potential of this rapidly growing scale.

HELJAN’s first British TT 1:120 models will depict two British Railways classics – the ever-popular Gloucester RCW Class 122 diesel railcar and the legendary Class 55 ‘Deltic’. First to arrive will be the Class 122 ‘Bubble Car’ in Q1 2026, followed quickly by the ‘Deltic’ in Q2 2026.

The first running samples of the Class 122 and Class 55 make their debut at Key Model World Live on April 26/27, where they will be running on Chris Hobbs’ ‘Camelot’ layout as part of the HELJAN display. Better known as YouTube’s ‘Peachy TT120’, Chris will be on hand over the weekend to discuss all matters TT!

HELJAN UK Representative, Ben Jones, said: “We’re very excited to be moving into TT 1:120 scale, which we believe has huge potential. Our first two models have been chosen to complement products that are already available from other suppliers, helping to build a broad and cohesive range of models that will attract even more new modellers to this superb scale.”  

Six Class 122 liveries and four classic Class 55 liveries will be available via HELJAN stockists on release (see below). All items are available to pre-order now.

Even better news is that we are 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 (see below) – a stunning collection that will appeal to ‘Deltic’ fanatics and TT layout builders alike. They will be joined by an exclusive BR Green Class 122 in early condition, ideal for use with BR steam locomotives and early diesels.

High Level Specification

While the Class 55 will be an ideal companion for Mk1/Mk2d 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. It’s a complete train in a single vehicle, suitable for everything from branch line micro-layouts to busy main line stations. Featuring outstanding detail and all the working functions you’d expect from a new ‘OO’ model, the Class 122 opens up enormous opportunities for British ‘TT’ modelling.

Starting with a blank canvas in a new scale allows us set a high level of standard specification across all products, which includes high-quality mechanisms with small but powerful motors, new generation E24 compact DCC decoder interface, allowing up to 32 digital functions (dependent on decoder), factory fitted speakers, authentic lighting functions and superb attention to detail throughout. In addition, the Class 55 will be the first HELJAN TT 1:120 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.

Other standard features include…

·      Detachable TT standard couplings

·      Factory Fitted Speakers

·      Authentic Lighting Functions

·      Separately Switchable Headcode Panel and Tail Lights (Class 55)

·      Separately Switchable Headcode Panel/Marker lights, Saloon Interior and Tail Lights (Class 122)

·      100s of Separate Detail Parts

·      Finescale Wheels

·      Etched Grilles (where fitted)

·      Outstanding Interior and Exterior Detail

·      Plug and Play DCC Capability

·      Authentic Detail Variations According to Period/Livery

The Class 55s will be offered with a wide range of authentic detail variations already seen on the latest HELJAN O gauge models. These will include cast or fabricated bogies, glazed or plated headcode panels and cab quarterlights, vacuum brake/steam heat and dual brake/dual heat versions, single or twin wipers and more. All models will be offered DCC Ready with an easy-to-access E24 decoder interface. Decoration will be the icing on the cake for these outstanding models, featuring a wealth of authentic detail across a wide range of attractive and popular liveries.
