The first production vehicles entered service in 1975 and continued to be built until 1988. \u003c\/p\u003e\n\u003cp\u003eAlthough outwardly similar to the Mark 2 carriage, it is of a completely different design, having a ridged roof and under-frame skirt, whereas its predecessor had a smooth roof and visible below-frame equipment. The body is 75ft-long (23m), which is 10ft (3m) longer than the Mk2. It is also of full monocoque construction (one piece body shell) with an all-welded mild steel, stressed skin.\u003c\/p\u003e\n\u003cp\u003eTo give it a superior smooth ride, it also has secondary air suspension and disk-brakes fitted to the wheels (rather than clasp brakes) which allow for running at speeds of up to 125mph (200km\/h) and efficient deceleration. \u003c\/p\u003e\n\u003cp\u003eThe Mk3 HST coaches differ from the Mk3A loco-hauled coaches mainly in terms of the electrical arrangements, but are otherwise much the same. \u003c\/p\u003e\n\u003cp\u003eThese HST coaches take their supply from a three-phase electrical supply directly from an auxiliary alternator in the power car, whereas the Mk3A convert the single-phase AC supply from the locomotive through motor generator units under the floor, which change the train supply to three-phase.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Hornby TT:120","offers":[{"title":"Default Title","offer_id":56975195439490,"sku":"TT4045A","price":24.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/0483\/9120\/files\/TradeWebSize-TT4045AGNERHSTMk3CoachTF_41170_Coach_2.jpg?v=1791805377","url":"https:\/\/goinglocomodels.com\/products\/hornby-tt4045a-gner-mk3-tf-coach-41170-tt-120","provider":"Going Loco","version":"1.0","type":"link"}
