Britain's Last HSTs in Passenger Service! ScotRail Class 43 Set Power Cars Numbers 43138 & 43149

Lead Power Car: Class 43 No. 43138
Built by British Rail Engineering Limited (BREL) at Crewe Works in June 1980 (entering service on 28/06/1980), 43138 is a 46-year-old Class 43 High Speed Train power car. Originally fitted with a Paxman Valenta engine, it was later re-engined with a 2,250 hp (1,680 kW) MTU 16V4000 R41 16-cylinder diesel engine driving a Brush alternator set, capable of a maximum operating top speed of 125 mph (200 km/h). Operating on lease to ScotRail for its flagship 'Inter7City' routes connecting Scotland's seven cities, 43138 carries ScotRail's dark blue livery featuring landmark city silhouettes.

Rear Power Car: Class 43 No. 43149
Constructed by BREL at Crewe Works in June 1981 (entering service on 08/06/1981), 43149 is a 45-year-old member of the world's fastest diesel class. Like its leading counterpart, 43149 underwent life-extension modernization, upgrading to a 2,250 hp (1,680 kW) MTU 16V4000 power plant driving Bo-Bo bogies through electric traction motors to maintain a 125 mph (200 km/h) service top speed. Wearing matching ScotRail Inter7City livery, 43149 works in push-pull formation on the rear, supplying supplementary power and electric train supply (ETS) for the set.

Rolling Stock: 5-Car Refurbished Mark 3 Rake
The train is formed of a short-form 5-car Mark 3 coaching stock rake, specifically refurbished for ScotRail's Inter7City network. Modernized with automatic sliding plug doors, refurbished interior seating, Wi-Fi, and controlled emission toilets (CET), these lightweight coaches allow the 2,250 hp Class 43 power cars to deliver rapid acceleration and high-speed performance across Scotland's main lines.

Seen in 8K 16:9 widescreen on its eastbound approach through Haymarket station in Edinburgh, a 5-car ScotRail Inter7City HST is captured passing through the platform lines. Powered by Class 43 43138 leading and 43149 on the rear, the high-speed set sounds its two-tone horns before plunging directly into the western portal of Haymarket Tunnel, completing its run into Edinburgh Waverley station on Sunday, 2nd of August 2026 at 15:29.
