Hornby has announced the latest additions to its growing TT:120 range, with a strong focus on British diesel traction and the rolling stock, buildings and infrastructure needed to create a convincing diesel-era layout.
Leading the new locomotive releases are a Class 37 in Colas Rail livery and a selection of Class 47 locomotives, with the Class 47s available in both analogue and DCC Sound-fitted versions. The new traction provides TT:120 modellers with further opportunities to recreate both contemporary and classic diesel railway operations.
The latest rolling stock releases include a mixture of Mk1, Mk2E and Mk2F coaches, offering plenty of scope for building authentic passenger formations behind the new diesel locomotives.
Hornby's latest announcement also expands the scenic side of the TT:120 range, with new terraced houses and shops, red brick tunnel portals and a selection of diesel-era railway buildings and infrastructure. These include portable cabin offices, a diesel fuelling point and storage tanks, helping modellers add realistic operational detail to modern and transition-era layouts.
Together, the latest releases further strengthen Hornby's TT:120 offering, giving modellers more options for creating detailed British railway scenes from the diesel era through to the modern day.
