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.

  1. The batteries don’t give the buses a long enough range.
  2. The buses don’t handle cold weather very well.
  3. The step into and out of the bus is too high for elderly people and is not the same as other London buses.
  4. The seating is more comfortable in AlexanderDennis, Evo-Seti and Wrightbus buses.
  5. The seats are also too narrow.
  6. The seats at the back downstairs are pokey, because of the position of the batteries.
  7. 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.
  8. The stop displays are unreliable.
  9. 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.
