Back To The Future With BYD Double-Deck Buses
Arriva run the 141 bus route for transport for London and today they must have been short of buses, as this older Wrightbus on a heritage number plate had been pressed into service.
The four pictures of an older Wrightbus hybrid bus, were taken on Moorgate this morning, when it was substituting for a newly-delivered BYD battery-electric bus on route 141.
As I tapped in, I made a remark to the driver about reliability of the Chinese buses and he smiled a knowing smile.
As an engineer and designer, I would list the design faults on the BYD double-deck buses as follows.
- The batteries don’t give the buses a long enough range.
- The buses don’t handle cold weather very well.
- The step into and out of the bus is too high for elderly people and is not the same as other London buses.
- The seating is more comfortable in AlexanderDennis, Evo-Seti and Wrightbus buses.
- The seats are also too narrow.
- The seats at the back downstairs are pokey, because of the position of the batteries.
- There is no rear view downstairs, which makes using the Mayor’s promoted Hopper Fare, which lets you take unlimited bus and tram journeys for £1.75 within one hour of your first tap-in, more difficult.
- The stop displays are unreliable.
- The buses don’t have enough seats for the 141 route.
But perhaps most importantly, few passengers have a good word for the buses.
John Baxendale’s Thermometer
Over the years, I’ve been involved with lots of innovative ideas.
When I worked at ICI Mond Division in Runcorn, one of the guys, that I worked with was John Baxendale, who was a fairly local lad, with unusually for the late 1960s, a very keen interest in surfing. John would often drive up to the North of Scotland in his green Morris Minor Traveller for a few day’s surfing.
Workwise, I remember John most for an electronic thermometer he built, that measured the temperature of a body by its black-body radiation, which is described in this Wikipedia entry.
He developed the thermometer to measure the temperature of remote objects and used to calibrate it on a handy ear, which is a very convenient black-body at 36.9 degrees C.
