The long drawn out saga of the Exeter Bus Station redevelopment had a milestone day recently, as a strong turnout of heritage and modern buses and coaches filled the station for a farewell event.
I say long drawn out because the station was due to have been closed by now and the running day on Sunday 19th March was to have been its final fling. But planning officers, contractors and the square wheels of bureaucracy conspired to delay the closure and the site remains open for the time being.
I played a small part in the running day by collecting Western National 3307, a 1979 Bristol LH6L/ Plaxton Supreme coach which belongs to the Westcountry Historic Omnibus & Transport Trust (WHOTT), from its storage yard and driving it in service during the day. Several other historic vehicles from the area queued for fuel in a nearby town before heading off for Exeter.
I’ve driven this LH before and, although it’s not my favourite type, I found it quite easy to drive smoothly. I had time before my first duty to wander around but, even before I’d stepped off the coach, my planned duties were changed and I found myself covering a duty that was left vacant by a bus which didn’t appear.
Instead of doing a few trips up Telegraph Hill and back I was given two turns out to Alphington and one to St David’s Station. I knew roughly how to get to Alphington (a suburb on the west side of Exeter) but got the finer details about where to turn the LH coach from my WHOTT colleague Inspector Andrews. I drove down Western Way to Exe Bridges, which was very busy as per usual. Passing the Marsh Barton Trading Estate, I turned left and drove through Alphington and turned on a small triangle on the edge of the village. We stopped there to wait time and several passengers took the opportunity to take photos.
Many of you will have seen, photographed, ridden in or driven Bristol buses fitted with the unusual Cave-Browne-Cave cooling system. So here’s a photo of one of the prototype buses.
This is Hants & Dorset 1068, a 1940 Bristol K5G carrying an early version of the cooling/heating system invented by Wing Commander T. R. Cave-Browne-Cave. He was Professor of Engineering at Southampton University at the time. The photograph comes from my own collection and came to light while I was looking for images for a new book I’m writing.
In a nutshell, the traditional radiator mounted in front of the engine is omitted and two – smaller – radiators are fitted either side of the destination display. These also act as forced air heaters for warming the upper deck. In summertime, when the saloon heating isn’t necessary, the warm air can be deflected through vents on the sides of the bus.
I’m not sure why the Wing Commander was commissioned to create this system because the traditional cooling system had been working reasonably well for decades previously and indeed continues in the same form to this day. Anyway, his first prototype installation was fitted to a Southampton Corporation Guy Arab. The test went well evidently and the second installation was fitted to a Hants & Dorset Bristol K, as shown above. The front cowl, obviously from a Lodekka, was a later modification because the original front was more obviously based on the standard PV2 radiator shape.
Cave-Browne-Cave obviously sold the idea to Bristol Commercial Vehicles/Eastern Coach Works and it was widely adopted as an option for Bristol LDs and F-series Bristols as we all know. Some more of Southampton’s Guy Arabs were also fitted with CBC, as were a few Bristol Ls of West Yorkshire Road Car.
Alongside occasional design work recently, I have also been tasked with delivering and collecting some of the Crosville fleet in preparation for the 2017 season.
This has meant a lot of solo mileage but fortunately the destinations have been familiar, so not too stressful. The first of these movements, a few weeks ago, saw me taking one of the Crosville hybrid deckers up to the Yorkshire premises of Cobus, the bus restorers. Last week I took another of the Wrightbus hybrid buses up to Cobus and, the following day, brought the first one back to Weston-super-Mare as its conversion to open top had been completed.
As before, the journey was slow and tedious. Don’t get me wrong, the bus is dead easy to drive around town as it was originally used on the (mostly flat) streets of London. But put a gradient in front of it and, just like a tired donkey, it gets all moody and unresponsive. Normally, power comes from a Cummins diesel engine which charges the propulsion batteries but in Direct Energy mode (used for these long journeys) these batteries are switched out and the bus relies solely on the relatively small diesel engine. Propulsion still comes from the Siemens electric traction motor but it can only deliver the energy provided by the diesel engine. Which isn’t nearly enough on hills. Even on motorways, where gradients are usually gentle, our speed dropped away alarmingly. At times we were down to about 30mph!
