Hornby unveils 2026 TT:120 catalogue with Black Five and Class 30/31 models

Hornby’s 2026 TT:120 catalogue does more than list fresh stock. It shows a scale that is moving from launch novelty toward a fuller operating programme, with steam, diesel, freight and engineers’ stock all advancing at the same time. The catalogue is on sale for £4.99 and is available direct from Hornby and TT:120 stockists.

The headline motive power keeps Hornby’s balance between eras intact. The new London Midland & Scottish Railway Black Five 4-6-0s include 5408 in LMS lined black, 45315 in BR lined black with early crests, and 45446 in BR lined black with late crests. The Class 30/31 A1A-A1A diesels widen the modern side of the range with D5502 in BR green, 31270 in BR blue, 31237 in BR Railfreight red stripe, and 31219 Cricklewood in BR Civil Engineers yellow and grey. Together, the two groups make a clear point: TT:120 is no longer being pushed through one nostalgic lane.

That breadth matters even more in the wagon section. Hornby is adding HBA and HEA hopper wagons, MEA box wagons, plus YGH Sealion and YGB Seacow engineers’ ballast hoppers. Hornby says the wagons will feature NEM coupling pockets, turned metal wheels and separately applied detail where appropriate, which is the kind of specification that matters once a layout moves beyond display and into regular running.

Hornby’s own framing helps explain why the 2026 catalogue lands with more weight than a simple release sheet. TT:120 is a 1:120 scale, and Hornby says a 4’6” x 3’6” board can fit two circuits and several sidings. The company also says TT:120 is here to stay and that at least five years of products are either being developed or planned. That long runway gives the range a different feel from a trial concept, especially for modellers planning a compact layout with room for proper operations.

The launch history underlines that shift. Hornby introduced TT:120 in October 2022 as its first all-new product range in 50 years, after several years of development and substantial investment. The original programme already covered locomotives, carriages, wagons, track, buildings and accessories, and the current free digital TT:120 Club now adds quarterly magazine issues, Train Terminal blog access and exclusive competitions. The 2026 catalogue makes the same argument in a more practical way: TT:120 now has the stock depth to support a credible layout, not just a shelf of isolated models.
