Class 90 commissioning 1988
The class 90 bo-bo locomotives were designed to complement the existing Class 87 and in fact were originally designated Class 87/2. They were designed for both locomotive-hauled and 'Push-Pull' operation and in the latter mode could be operated remotely from a Driving Van Trailer (DVT) vehicle using a Time Division Multiplex (TDM) system of control by which 'signals' are sent through the standard Railway Clearing House (RCH) lighting jumper cables to operate the controls of the locomotive.
I remember undertaking TDM trials on the WCML with a couple of class 85s and a rake of Mk2 coaches, mainly between Crewe Basford Hall and Stafford. The locos were not permanently fitted for TDM just 'jury-rigged' and monitored.
Later when the Mk3 DVTs arrived they were also trialled in a similar way but with a class 86 which would be coming off works fitted with TDM kit.
Rated at 5,000 HP with a maximum permitted speed of 110 mile/h they were well able to deal with the passenger services on the WCML
90 001 was delivered to the RTC, Derby for trials in late Autumn 1987.
The fleet of 40 locos were introduced onto the WCML in 1988 and I was part of the team responsible for the commissioning of the locomotives.
