Double Railfreight Grey Class 31s! Locomotive No. 31210 And 31108 Shunting at Horsted Keynes Station

Lead Locomotive: British Rail Class 31 No. 31210 in BR Railfreight Grey
Constructed by Brush Traction at Falcon Works in Loughborough, Leicestershire in July 1960 (works number BT234, originally entering traffic as D5634 and renumbered 31210 under TOPS in 1974), 31210 is a 66-year-old A1A-A1A mixed-traffic diesel-electric locomotive. Re-engined during British Rail's major fleet refurbishment programme, the locomotive is powered by a 1,470 hp (1,096 kW) English Electric 12SVT 12-cylinder turbocharged diesel engine driving Brush electrical generator and traction motors. The locomotive has an overall operational weight of 111 tonnes (109 imperial tons), a maximum starting tractive effort of 35,900 lbf (160 kN), a fuel capacity of 3,600 litres (800 imperial gallons), and a maximum service top speed of 90 mph (145 km/h). Locomotive 31210 is immaculately turned out in authentic unbranded British Rail Railfreight Grey livery, complete with full high-visibility yellow warning front ends, a dark grey/black cab roof, red bufferbeams, and period cabside numerals.

Coupled directly behind the lead locomotive is classmate 31108, constructed by Brush Traction at Falcon Works in Loughborough in October 1959 (works number 129, originally entering service as D5526 and renumbered under TOPS as 31108 in 1974). At 67 years old, 31108 is also powered by a 1,470 hp (1,096 kW) English Electric 12SVT 12-cylinder turbocharged diesel engine driving Brush traction gear. The locomotive possesses a matching operational weight of 111 tonnes (109 imperial tons), a starting tractive effort of 35,900 lbf (160 kN), and an operating top speed of 90 mph (145 km/h). Finished in an identical, pristine British Rail Railfreight Grey livery with full yellow warning front ends and cabside numerals, 31108 is distinctively fitted with heavy-duty three-piece miniature snowploughs mounted beneath its bufferbeam. Together, this double-headed Brush Type 2 pairing delivers an aggregate power output of 2,940 hp (2,192 kW), a combined weight of 222 tonnes, and a starting tractive effort of 71,800 lbf (320 kN).

Shunting South at Horsted Keynes Station
Captured in 8K 16:9 widescreen during a busy period at the Bluebell Railway's Network SouthEast 40th Anniversary Diesel Gala, Class 31 No. 31210 leads classmate 31108 on a light-engine shunting move heading south out of Horsted Keynes station. With the station platforms and sidings filled with period Network SouthEast rolling stock, the two pristine Railfreight Grey locomotives rumble past the historic Horsted Keynes signal box. Running on a warm summer's afternoon on Sunday, 6th of September 2026 at 17:33, the twin English Electric 12SVT engines can be heard gently gurgling and rumbling at low idle as they roll into position near the southern shunt signal, manoeuvring for their next operational duty.
