London Transport Chiswick H30/26

The STL – the letters stand, rather confusingly, for ‘Short T Long’ – was introduced into London area service firstly by Thomas Tilling in October 1932 and then by the London General Omnibus Company in January 1933. The STL Regent then became the standard double decker for the new London Passenger Transport Board which came into being on 1 July 1933. The chassis was the latest version of the AEC Regent which took advantage of new regulations that allowed for the extension of the overall length from 25ft to 26ft on a wheelbase of 16ft 3ins, and an increase in the rear axle loading from 9½ to 10 tons. The LPTB STL class then reached a total of 2647 by the commencement of war in 1939, and a further 34 unfrozen chassis were added from the end of 1941. Twenty more buses complemented the STL class in 1946, but these were very different beasts from the LPTB specification, being standard post war AEC Regent II machines with provincial style Weymann bodywork. An example of which can be seen here
The STL class underwent several specification changes over its production run and subsequently in service – engine changes (petrol/indirect injection diesel/direct injection diesel) and many bodywork swaps, some arising from the attrition of wartime. STL 2093, DLU 92, seen above during the HCVC Brighton rally of May 1971, was a 1937 chassis powered by the AEC A171 indirect injection 7.58 litre diesel driving through the AEC D132 four speed spring operated preselector gearbox. It was initially bodied by Park Royal, but, being damaged in an air raid, it was sent to Birmingham City Transport for repair in 1944. By 1949 the body was deemed past further use and it was scrapped in February of that year. STL 2093 then received the Chiswick built body from 1939 vintage STL 2570, the chassis of which was then selected to join the expensive and ultimately fruitless SRT conversion programme, under which newer STL chassis were ‘upgraded’ to carry the heavier RT bodywork. Sadly, not only were the SRTs under powered but, more seriously, they couldn’t stop, and the whole wasteful exercise was abandoned ignominiously. This OBP entry contains comments on the SRT debacle. www.old-bus-photos.co.uk/
Meanwhile, now carrying its Chiswick body, STL 2093 soldiered on, even seeing a short spell during 1949 as a Green Line coach on route 703 at Swanley, until its withdrawal from passenger service in 1954 along with the rest of the pre-war/wartime STL class. It was then sold in 1955 to Reliance Services of Newbury who in turn passed it on to a private owner for preservation in May 1958. This was Dennis John Cowing, a chemistry master (and transport enthusiast) at Selhurst Grammar School in Croydon, a master contemporary with my own attendance in a less elevated capacity at that establishment. Mr Cowing rallied the bus for many years and he is driving it in the 1971 picture, but, by 1976, the structure of the vehicle had degenerated alarmingly and it passed into the ownership of Prince Marshall for full restoration. That has since proved to be a mammoth undertaking, currently in the hands of the former Cobham, now Brooklands Museum, where it has more recently been displayed as a bus victim of the blitz.

I have gleaned information from various sources for this note, but, as ever, Ian’s Bus Stop has been invaluable.

One of my favourite buses, in roof-box form, along with the Bluebird LT’s. A shot which brings out the best of its design and in a condition which suggests it’s only been on the road for a few weeks after delivery to LT. Only the parked Ford 105E gives the game away! Yours, Roger? My last glimpse of a working STL was in June 1955. When waiting at traffic lights, one passed across me. It must have been a garage hack on one of its last journeys.
