You are correct David, I am merely giving my observations as a passenger.
The reasons LRT give are fare evasion, together with accidents involving the rear doors being shut on passengers. This is despite the modern Tridents with dual doors having a buzzer or siren which sounds when the doors are shutting, akin to on the tube. First South Yorkshire bought a load of secondhand Olympians which had back doors, however drivers frequently don't open them either purposefully or accidentally - so if you're waiting to get off there it's either walk to the front or open them yourself.

Knowing the way First S Yorkshire drivers behave, they would deliberately not open the centre doors to be awkward. IMO the present layout of London 'deckers like the WVLs is the best, with the exit door further back.

If 12 metre double deckers indeed have the same turning radius as a bendybus (as someone mentioned) It was me. Rationale: 18 m bendy bus is a 12 m bus with its rear end removed and a trailer attached instead ;D. Mercedes Benz Citaro (arctic) 49 seats +91 standing = 140. And I don't think you have much chance to overload it . The driver should look at the road, not at the passengers. The other problem with multiple doors is if the driver forgets he's on a dual door bus and opens the front doors out of habit, leaving people standing at the back door. LiAZ-6212 drivers, who have to deal with 4 doors, are known to install the 'master open' and 'master close' buttons.

I note that Ken said that he would dispose of the bendy's if there were more fires... I noted from last nights post 10 o'clock London local news that TfL had commented that the fire was not related to the cause of the previous fires.... IMO the bendy's were purchased as a means to take up more road space and therefore cause more traffic problems.... therefore encouraging drivers to ditch their cars... I may be completely off the mark here but that was/is the impression that I get

I think that even 140 is a conservative figure for the capacity of a bendy bus. They really do fit loads and loads of people; there's so much empty space in them. I'm a frequent user of the 29/N29 and I'm quite happy with bendies. This route is always full, and there's a reason that it runs every 6 minutes all night long. With such high passenger numbers it really is important that you can enter and exit throughout the bus. How many times do double decker buses drive past because they're completely full? Yet with bendy buses, it always seems possible to fit in a few more.

Perhaps then the solution is to design a double-decker with the internal layout of a bendy and, if possible, allow standing passengers upstairs. I don't know what the reason is why this is normally not permitted - I have been a standing passenger upstairs on an old (old R reg iirc) double-decker in Swansea, where overloading of the student busses wasn't uncommon in the peaks (I've also been stood forward of the driver (instructed where to stand so I didn't block the view), and stood on the step right by the doors). Even if they had bendybusses in Swansea they couldn't put them on the 82/82A/83 student services as there wasn't enough space for them to make the three-point turn at the student village end of the route, and I'm not certain the reversing manoeuvre at the bus station end would be safe either.

Fires seem to be endemic to bendy buses Certainly not . Can't help wonder which ones. We have many "Ikarus-280" and "Ikarus-435" buses, and neither one has anything close to what you describe.

I don't know what the reason is why this is normally not permitted A little known fact - in 1938-39, 10 double deck YaTB-3 trolleybuses were built in Yaroslavl to work in Moscow. In mere 1.5 years almost all of them were put aside, one of the main reasons - a very high (4.7 m) vehicle became dangerously unstable with many passengers standing upstairs and no real means to avoid it .

I think the reason why you can't stand upstairs on a decker is a mechanics one - the centre of gravity may be increased.
I've been on buses where I've had to stand at the front next to the cab as there has been nowhere else to stand. One driver got shirty when he turned up in the peak time in a little 26 seat Dart instead of a 51 seat B10M, and the only place I could stand was at the front. Er, what do you expect if you use a minibus on a board which should be worked by a full sized one?

Increasing the area of the base, and lowering the centre of gravity makes a vehicle more stable.

I'd have thought that low-floor buses would help in this regard, lowering the centre of gravity. If you also maximise the design of the chassis and internal fittings for maximum lower deck passenger capacity so you get the largest weight downstairs this will help as well. Possible design changes include moving the stairs to the outside rear of the bus so they don't take up room inside that could otherwise be used by passengers (like, say, a Routemaster), longitudinal seating downstairs to maximise passenger capacity (it works on a C stock) and bench seating rather than individual seats (three children or small adults can use the same space occupied by two large adults). You could increase the width of the bus, but with the narrow streets this country has this leads to more traffic jams - I have a friend in Bristol who will go on at length about the stupidty of the modern wider buses as they cannot pass each other on his street and sometimes have to mount the kerb to get around parked cars.

We had a bus almost wrecked when all the kids upstairs deliberately moved to one side as it went round a corner: the extra weight (leverage) on that side of the suspension actually bent the shock-absorbers and it had to be removed for repair (all really to do with the statutory tilt-test).

Come to think of it, one bus company I drove for had a local council contract to take kids from junior school to the swimming pool for lessons - this was always a single deck job as it was never more than 30 kids (plus a few adults, of course). On one particular occasion, the only available bus in the yard was a 'decker - much to the kids delight - and they all wanted to go upstairs. I had no objection and neither did their teachers/adults. It wasn't long before I noticed that having all your passengers upstairs (even kids) really ain't a good move ;D ;D Their faces really got me on the return journey when I said they couldn't go upstairs ..........

But ground clearance suffers which can be a problem in rural areas such as ours Have you SEEN pics of that sorrt of bus from the '20s? How does that help? All SLF buses have very few seats anyway. How about instead going on about the stupidity of alllowing parking on major bus routes anyway? Punters in those streets demand buses then do their utmost to stop them by parking as they please. Buses have been the same maximum legal width for over 30 years now: it is only the size of the local car-owning resident's brain that has altered........................

I hadn't thought about ground clearance - that's a good point for rural areas, but do you need the super-capacity buses on rural routes? I'd have thought that it would only be needed on routes that encounter nothing more severe than speed bumps?
I haven't seen pictures of those sorts of buses so I can't comment. Please can you point me in the direction of some so that I may be educated in this regard.
My point, although not well made, regarding the seating was not so much the number of seats but their layout being such as to maximise standing capacity.
In the streets around where he lives there are only a handful of properties with off-street parking, so with the dire public transport provision in Bristol (and expense of what there is) most households require at least one car. I do suspect that the modern buses are being compared with ones that are at least 40 years old if not more; I'm not familiar whether these are thinner or not, and whether or not they were built to the maximum permitted width. Certainly the width of private cars has generally increased over the years. One of his points is that the bus routes should be altered so that where possible they run in different directions on parallel streets. Although with the pinch points that I am familiar with on the services between Wells/Winscombe and Weston-super-Mare (Banwell (Castle Hill/East Street/West Street), Cheddar (Church Street/Draycott Road and Axbridge Road) and Westbury-sub-Mendip (Wells Road)) - there are no alternatives.

All the bendies (and the non-articulated Mercedes benz Citaro's) were apparantly fitted with "fire supression equipment" ... it doesn't look to have been very effective !
A recent batch of East Lanc's bodied Scania's failed the "tilt test" after the addition of various items for TfL spec. To pass they had to loose a couple of seats upstairs and carry a large concrete block downstairs !
Modern buses are certainly wider and longer than their predecesors, and if switching from a Routemaster to a Trident, one must remember the front wheels are behind the driver rather than infront, requrirng a different line on bends !
Bendies are cattle trucks, they may have had a niche for use on the Red Arrows or school services, but I prefer to sit in comfort. If a bendie and a double decker turn up together I get on the double decker !
I've been on hopelessly overloaded route 25 bendies and the driver simply can't get the doors closed (they spring back open on contact with someone or thing ).
If a modern day, accessible Routemaster successor can be developed for London then so much the better ...Artic's are not it !

Thought Olympians/Dominators/Metrobusses were *slightly* narrower than the new Tridents. I'm asking because Hong Kong took a couple of years to update the width regulations to the EU standard. When it was done, the Tridents etc. that came in new were wide enough to accomodate 2-2 wide seats on the lower deck without compromising aisle width.
Aspect, the 25 really is one very unique route in London! Even when its full, I'm pretty sure it hasn't exceeded the Licenced capacity by people count! I really cannot imagine more than 60 people standing in that thing.

The routemaster was beset with many problems when it was introduced! 2,000 modifications were fitted after introduction!
The RMs trump card was its weight saving. They were going to fit a single aperture blind to save weight but decided against it because of the passengers opinions. An 8 ton RM seating 72 compared to a 12 ton low floor bus seating a similar amount but using so much more fuel per passenger. The RM was the best engineered bus ever built and probably the best bus ever built. Built for its purpose and carrying on from the Frank Pick's legendary leadership of LT.

The Routemaster is a great design but it is lighter because it's shorter and narrower than modern busses. A RM has width to support 2-2 "narrow" seating.
Modern wide busses initially came with "narrow" 3-2 seating but with people getting fed better these days, the standard has become "wide" 2-2 seating. The increased width also increased standing capacity. If you fit "wide" seats into a routemaster it would be a 2-1 config, resulting in approx 15 less seats. Therefore, modern busses aren't not as weight inefficient as they may seem.
A low floor bus results in the loss of approx 10 seats versus an Olympian. The low floor is responsible for the loss of 6 seats as people cannot sit sideways above the wheels anymore. Another 4 seats is lost because of the modern "straight" staircase instead of the old spiral resulting in one less row of seats.

Con-duc-tor... What is that... ;D I agree with Chris, but I can't ever see it happening, as it would mean having to pay more wages, for something a driver is already paid to do... First's "FTR" schemes in York and Leeds feature "Customer Service Hosts" who sell tickets and so on, allowing the "Pilot" (driver!) to drive without being bothered by passengers. It's a conductor by another name...! Obviously the FTR idea is a little different from standard routes anyway and there are various reasons why they need conductors on those buses, so I'm not suggesting that it would necessarily work in London on buses with conventional bodywork.

I really cannot imagine more than 60 people standing in that thing. I rather like the route. I have driven it in MCW Metrobus's, Dennis Arrows, Dennis Trident/Alexander, Dennis Trident/Plaxton President (Long and short) and Routemasters. Though, I am pleased to say, never a Mercedes Benz Citaro! You'd be amazed at the antic's of (the very different) passengers on this route !

But not a Titan? ;D In all seriousness, that's a rather impressive list you have! It indeed is a very interesting (and intimidating) route, as it leaves the UK and enters Bangladesh!
All I've seen on the 25's lots of pushing and shoving as it's almost always packed to the brim (but not "overloaded"). I guess since its a bendybus, the scum need not interact with the driver. I can understand your point about the antics though - the 205 which carries the same passengers (to Mile End) is a standard bus and I've seen some rather heated exchanges with the driver, and an attempted faredodge!
However, I have heard the 25 has one of the highest incidence of drivers hitting the emergency button for police help.
(The DMS is a very accecible successor to the Routemaster and all other modern busses have followed suit! ;D Give me a DMS over a bendy any day...)
