I've tried counting how many passengers there are on my morning commute on the 29... I really don't think 140 is far from the actual maximum capacity. Most of this is obviously standing passengers, which double deckers can't take many of due to no standing space upstairs, the stairs going up and the general seating layout.

You will lose capacity. Diamond Geezer describes it perfectly on his blog: As an example, the 38 bus in morning peak, now and in a year: Now: 20 bendy buses - frequency of every 3 minutes - capacity of 2980 passengers per hour (bendy bus capacity of 149 passengers per bus) Situation in a year, with double decker buses: 28 double deckers - frequency of every 2m10s - capacity of 2380 passengers per hour (85 passengers per bus on a DD) So that's a capacity decrease of 600 passengers per hour! The reason I said that frequencies may actually decrease is because the 38 bus is madly busy, which means that there is a very good chance that you won't be able to get on the first double decker bus anymore in the future. That's why I think that the the frequency of buses you can actually get on will very likely also be going down. Post is here, by the way: diamondgeezer.blogspot.com/2008_12_01_archive.html#6418556667188970785Assuming a bendy can actually carry 149 (I've never used one but various sources say that figure has always been questionable)..... Presumably not every bendy is full to capacity, so I wonder if the 600 difference could be absorbed? And on the plus side, available seats will pretty much double. I take your point overall though. |

You can fit more than 85 on a double decker. 104ish is more like it (H51/32F plus 21 standees) - if operators purchase smaller buses then that's their choice, however larger ones are available. That makes the figure something like 2,880.

LT tried something like you describe in the 1980's Alternative Vehicle Evaluation trials. See herethe problem at the time was not being able to see the rear exit doors - something that could be solved with CCTV nowadays. The bus was liked by the engineers at Chiswick because of the front engine layout being the easiest to maintain. Tri-axle buses (as used in Hong Kong) have been suggested for the ex bendy routes - and its not a bad idea TBH. It's only TfL being cautious. The tour buses use tri-axle 12m buses in central London with little trouble. |

Nope, they can seat about 120 I think! I was talking about a bog standard Trident or Gemini - granted it would be a wee bit lower if you had a double door version but still higher than 85 total! |

I don't remember the make, but the old Y registration double deckers buses used in Swansea when I was a student had a rated capacity of, iirc, 91 including standees. These were single door step entry vehicles, roughly the same length as the 49 passenger capacity single deckers (shorter than the modern 60ish capacity single deckers that were arriving when I left).
Surely even a modern low-floor bus can take more than 85 pax.
