BR Large Logo Blue Class 50 Defiance Number 50049 Blasts Away from Oxenhope Station on The KWVR

British Railways Class 50 Co-Co diesel-electric locomotive number 50049 (originally entering service under the pre-TOPS scheme as D449 and famously named "Defiance") was built in 1968 by English Electric at the Vulcan Foundry. This 115-tonne Type 4 mainline locomotive is powered by an English Electric 16CSVT 16-cylinder turbocharged diesel engine which generates 2,700 brake horsepower. Utilizing a GEC electrical transmission system driving six traction motors, the locomotive is geared for a maximum operational top speed of 100 mph and exerts a starting tractive effort of 48,500 lbf. Maintained under the pride of the Class 50 Alliance / Fifty Fund, this iconic machine is turned out in its striking historical BR Large Logo blue livery, featuring full wrap-around yellow cabs, a dark blue body shell, and oversized white numbers.

The locomotive is seen here in 8K 16:9 widescreen thunderously powering out of Oxenhope Station during the Keighley and Worth Valley Railway Summer Diesel Gala. The train is captured making an epic departure, treating lineside onlookers to a roaring display of classic English Electric power on Saturday 20/06/2026 at 12:09.
