Hornby Railways OO Gauge – RailRoad – BR Mk.3 Coach – Intercity 42045 TSO Coach

This Trailer Standard Open ‘TSO’ InterCity Mk3 coach is an ideal coach to add to the B.R. High-Speed Train Set to increase the rake of coaches between the two Class43 Diesels. Mk3 coaches entered service in 1975 along with the Class 43 forming the iconic InterCity 125 trainset. After the HST Mk3 coach variant was introduced, further Mk3 coaches were introduced to the West Coast Mainline for use as part of locomotive-hauled trains. Whilst Mk3 stock is standard for HST units, the standard locomotive hauled stock is Mk3a. Mk3a stock differs from Mk3 stock due to the inclusion of buffers and a different electrical system that uses motor generator units in each coach to power air conditioning and other ancillaries. Mk3a stock was built until 1984, before 3B stock with improved seating and lighting was built from 1985 to 1988.
