Iconic 125mph High Speed Train at Haymarket! ScotRail HST Class 43 Power Car Numbers 43149 And 43138

Lead Power Car: ScotRail Class 43 No. 43149
Built by British Rail Engineering Limited (BREL) at Crewe Works in 1980, 43149 is a 46-year-old Bo-Bo High Speed Train (HST) diesel-electric power car operated by ScotRail. Powered by a 2,250 hp (1,680 kW) MTU 16V 4000 R41 twin-turbocharged V16 diesel engine coupled to a main alternator and four traction motors, the 70-ton power car is capable of a top design speed of 125 mph (200 km/h). Outfitted in ScotRail's iconic 'Inter7City' navy blue livery, 43149 provides front-end traction for high-speed cross-country services across Scotland's main rail arterial routes.

Rear Power Car: ScotRail Class 43 No. 43138
Built by BREL at Derby Litchurch Lane Works in 1980, 43138 is a 46-year-old Bo-Bo HST power car operating at the rear of the set to provide push-pull capability and auxiliary train power. Also powered by a 2,250 hp (1,680 kW) MTU 16V 4000 R41 diesel engine, 43138 delivers a matching 125 mph (200 km/h) maximum operational speed. Working in tandem with 43149 via multi-unit control, it carries matching ScotRail Inter7City branding, forming part of the iconic InterCity 125 configuration that has served British mainline railways for over four decades.

Rolling Stock & Inter7City Fleet
The train conveys a rake of 5 British Rail Mark 3 carriages (built between 1975 and 1988), which have undergone extensive structural re-engineering by Wabtec to modernise them for 21st-century passenger service. The primary modification includes the replacement of classic manual slam doors with modern power-operated automatic sliding plug doors, alongside controlled emission retention toilets, accessible seating layouts, passenger power outlets, and modern interior lighting. ScotRail's Inter7City fleet links Scotland's seven cities—Edinburgh, Glasgow, Aberdeen, Dundee, Inverness, Perth, and Stirling. Following mainline withdrawals across England, these heavily modified ScotRail Mk3 sets and Class 43 power cars represent some of the very last operational High Speed Trains in scheduled mainline service anywhere in the entire United Kingdom.

Seen in 8K 16:9 widescreen travelling west through Haymarket station outside Edinburgh on an empty coaching stock (ECS) transfer from Edinburgh Waverley station to Haymarket depot shortly after completing the return leg of an express service from Inverness to Edinburgh Waverley, ScotRail Class 43 HST No. 43149 leads a rake of five heavily modified Mk3 coaches with power-operated modernised doors, passing through Haymarket station at a steady speed with Class 43 No. 43138 bringing up the rear on a beautiful summer's afternoon on Sunday, 2nd of August 2026 at 14:31.
