TT4043B – GNER HST Mk3 '42242' Trailer Standard Coach (TT:120 Scale)

Capture the spirit of high-speed intercity travel with the TT4043B GNER HST Mk3 Trailer Standard Coach '42242', available now from TMC.

Finished in GNER’s distinctive deep blue and red livery, this TT:120 scale model embodies the golden age of express services on the East Coast Main Line. With accurately applied branding, fine detailing, and a carefully recreated interior, the coach delivers a true-to-life representation of the Mk3 TS (Trailer Standard) as it appeared in service during the 1990s and 2000s. Running number 42242 was part of the iconic High-Speed Train sets that redefined long-distance rail travel in the UK.

Developed in response to competition from air and road transport in the early 1970s, British Rail’s Mk3 coaches introduced a bold new standard in rail design. With a 75ft monocoque steel body, ridged roof, underframe skirting, air suspension, and disc brakes, the Mk3 offered both enhanced comfort and performance, capable of speeds up to 125mph. The HST variants, such as this coach, received their power from a three-phase supply via the train’s power car—setting them apart from the Mk3A loco-hauled equivalents.

An essential addition to any modern-era TT:120 layout, the GNER TS 42242 pairs seamlessly with other Mk3 coaches and HST power cars.
