Not many Crossley buses ever found themselves too far from their natural habitat of the North-West, but a sprinkling of them worked on the South Coast. Having bought mainly Leyland TD’s during the 1930’s, and PD’s after the war, too, Portsmouth Corporation dabbled in Crossley DD42’s briefly. Four DD42/5T’s were acquired in 1948, with locally-built Reading bodies. Another two of these arrived in 1949, followed in quick succession by a further 17 DD42/7T’s, all with Crossley bodies with two stepped side windows – very stylish!
The T suffix indicated that they were fitted with Brockhouse Turbo-converters, which performed rather like the Leyland Gearless buses in the 1930’s. I never knew why they were purchased without conventional gearboxes, because the trams were scrapped in the mid-30’s and the trolleybuses not until 1963, so the purchase was not catering to drivers without skills of gear-changing! When the buses pulled away, the engine note would rise up to the governor and stay there until the driver approached a bus stop. He would then take his foot off the throttle, the engine would then tick over and the bus would coast, freewheel-style, until the brakes were applied to stop. I never knew if these vehicles had a direct-drive ‘top’ gear which could be engaged – maybe the bus stops were too close to each other and the terrain too flat for drivers ever to engage it ‘anyone know?’. Crossley buses always gave out a rather ‘woolly’ engine note, as if being slightly strangled in some way. When pre-war Leyland TD4’s were being withdrawn in the late 1950’s, their 20 year old engines and gearboxes were transplanted into the Crossleys, which made them sound very odd after that. It surely improved fuel-consumption, though! Seating was initially H28/26R, but most became H32/26R in 1959/60, the very time the Crossley 100bhp engines were replaced by the 93bhp Leyland engines! Good job all the routes were as flat as a pancake, bar one railway bridge! They were mainly withdrawn in 1966 and 1967, the engines being 30 years old by then!
Here is No. 35 (EBK572) in Edinburgh Road, just off the main shopping centre of Commercial Road, in 1965, by which time these buses were usually relegated to peak-time extras.

The Turbo-Transmitter fitted to some Crossley DD42s did have a direct-drive top gear, but it was engaged automatically rather than by the driver.

Crossleys were, indeed, strangled, or at least the engines were. An innovative firm with no idea how to fully exploit this commercially, Crossley designed a very good engine for post-war production using Swiss Saurer technology. Crossley realised they needed to pay Saurer for the license to do so but were either unwilling or unable to do so. They took away the Swiss technology – to do with the "breathing" and fuel injection system – and ended up with a "dog".
This had a domino effect. People only bought Crossleys, post-war, because they were available and people were desperate for anything in the late forties. It also led to their demise and take over by AEC. Birmingham Corporation were happy with their late Crossleys but they had had the benefit of AEC engineers modifying the engine.
Nevertheless, AEC still thought highly enough of Crossley to give them the task of developing the Bridgemaster. Not only that, the Crossley Coachworks – which outlasted the engineering by eight years – produced bodies of high quality. Latterly this was to Park Royal design and, like Roe, subcontracted from Park Royal to help when the London branch was already busy. (This included a batch of Diesel Multiple Units for British Rail which are known as the Park Royal class but were built for them by Crossley at Stockport.)
Many Crossleys, particularly in Manchester, were re-engined by Leyland power – often second hand. This extended their lives to a ripe old age.

Perhaps worthwhile to mention that Crossley had another foray into the railway scene, with its 8-cylinder low-speed two-stroke engine fitted in the infamous "Metro-Vick" diesel electrics, which would have been Class 28 in BR terminology if they had lasted long enough. The locos were peculiar unbalanced machines with a six wheel bogie at one end and a four wheel at the other. I remember them working in pairs during the early 60s on St Pancras – Manchester expresses. Sadly they covered themselves in infamy, being afflicted with more problems that most, and having a tendency, as I recall, to burst into flames spontaneously! They were withdrawn after a service life of only 9 years.
