Glasgow 812

For most people nowadays the term ‘regenerative braking’ is likely to conjure up an image of state-of-the-art hybrid-engined motor vehicles. These attempt to reduce fuel consumption – and also CO2 emissions – by converting kinetic energy (forward momentum) into electrical energy by recharging an on-board electric motor for subsequent use in powering the vehicle. Few people are probably aware, however, that this innovative approach to energy conservation and re-use was originally pioneered on electrically powered railed vehicles including trams and also on trolleybuses, where the energy that was recovered in braking was either used to feed back into the overhead power line or to provide a form of electrical braking to impede the vehicle’s forward momentum.

Improbable as it sounds – since it was originally built in 1900 in Glasgow Corporation Tramways’ Coplawhill Works as a relatively primitive uncanopied, unvestibuled open-top tramcar – some of 812’s contemporaries came to be fitted with the then highly innovative regenerative braking mechanism as part of a comprehensive upgrade and modernisation process that they received in the mid 1930s.

Glasgow Corporation’s policy over many years was to extend the life of its ‘Standard’ tramcars by subjecting them to a rolling modernisation programme in an attempt to ensure that comfort levels for passengers and crew were not too badly eclipsed by advances in rival motor bus design and technology. So although 812 was one of the oldest trams in Glasgow’s fleet of over 1,000 ‘Standards’ that were built over a 25-year period between 1899 and 1924, it was progressively modified and upgraded during this period as tramcar design evolved.

Modification

Top deck cover added in 1910 but balconies still open; drivers’ vestibules added two years later. Fully enclosed as part of modernisation programme in 1930. The truck wheelbase was extended to 8ft with roller bearings. Trolley pole replaced by Fischer Bow collector at around the same time.

In 1965 it was decked out with its current yellow route colour.
A substantial body overhaul was carried out in the late 1970s- involving separation of both decks.
