the service ran from London Victoria calling at Clapham Junction, East Croydon (sometimes via Redhill) and Gatwick Airport running via Haywards Heath to Brighton. The service was transferred to InterCity with Class 73 electro-diesel locomotives (electric third-rail current or diesel-powered) hauling Mark 2 coaches and a modified driving motor carriage were introduced in 1984 in push-pull mode. When InterCity took over, the service only served London Victoria and Gatwick Airport. Sleepers – Originally consisted of Mark 2 or Mark 3 seating coaches with Mark 1 sleeper cars. Mark 3 sleeper cars replaced the Mark 1s in the early 1980s. DVTs were not used. The Night Riviera (Paddington-Penzance) was hauled by Class 47s while the Euston-Scotland sleepers were usually hauled by Class 86, 87 or 90 electric locomotives as far as Edinburgh and Glasgow. The sections north of Edinburgh were hauled by Class 37 or 47 diesel locomotives to/from Aberdeen and Inverness, while the section to/from Fort William was hauled by Class 37s. The London Euston to Stranraer Harbour service worked on the same basis with a change from electric to diesel at Carlisle. The service to Holyhead saw locomotive changes at Crewe. Fleet details Train formation Formations of HST and push–pull train sets would always place the driving van at the London end of the train, then two or three first-class carriages, restaurant and buffet car, and 5 standard-class carriages; the locomotive would always be at the country end of the train. The only exception was the London to Norwich route. As Crown Point depot is to the south of Norwich station, the locomotives worked from the London end as this facilitated easier loco changing at Norwich if necessary. Operating trains in push-pull mode eliminated the requirement to attach locos at terminus stations in order to turn the trains around. This also saved maintenance costs and reduced the number of locomotives and carriages needed to operate the services.
