BR Intercity Mk3 Tourist Standard Open 42199 - Era 8

Hornby’s range of TT:120 scale passenger rolling stock continues to develop with the addition of essential HST Mk3 carriages. Now replicating the popular InterCity Swallow livery synonymous with the 1980s, the new Mk3 range is a must for diesel-era modellers. Add this Mk3 to your HST from the Key Model World Shop.

The British Rail Mk3 formed a new generation of carriage design that revolutionized train travel in the UK and remains in service to this day. Delivered in HST (Mk3) and loco-hauled (Mk3a) variants, the new carriages included advanced systems for suspension, braking and air conditioning. Entering into service in 1975, the Mk3s are synonymous with the ground breaking Class 43 HSTs which operated in sets of between six and nine Mk3s.

The all-new Hornby TT:120 Mk3 range includes the commonplace Tourist Standard Open (TSO) as 42199 in the stand-out InterCity Swallow livery that adorned HSTs during the 1980s and 1990s. Accurately featuring flush tinted glazing, the new Mk3 TSO includes a fully detailed interior and realistic tampo printed decoration for a cross country or mainline HST of the period.

Intended to run with Hornby’s impressive class 43 HST power cars also carrying Intercity Swallow (TT3022M), four identities of TSO are offered to easily complete a prototypical HST InterCity 125 rake of eight Mk3s. With few trains as iconic as the HST, replicating a full set is straightforward and a must for any sectorisation (era 8) TT:120 scale layout.
