The other two locomotives were intended for freight train use, and geared for a top speed of 80 mph; these were designated Type B.

[4] Before the work was completed, BTH amalgamated with Metropolitan Vickers to form AEI (Associated Electrical Industries) traction division[4] and it was under this name that the locomotives were built in 1959 under subcontract by Birmingham Railway Carriage & Wagon in Smethwick.

However, this approach was never used on the West Coast main line, although it was employed elsewhere such as Glasgow Central in the initial 'Blue Train' electrification there.

The remains of E3009 were also cut up at Crewe Works, the locomotive having been wrecked in the Hixon rail crash of January 1968.

[7] Two further members of the class saw relatively early withdrawal due to accident or fire damage: The remaining locomotives of the Class had relatively successful service lives of 25 to 30 years, although in their latter years they became unreliable, and displayed an increasing tendency to catch fire.

[7] One example, 81002, has been preserved by the AC Locomotive Group, located at Barrow Hill Engine Shed.
