These were once quite popular in India and other parts of the sub-continent

They look like they were a decent idea.Having the Mercedes prime mover would be a bonus for reliability.

Probably a TATA ripoff rather than a genuine MB though.

That's not a bus. this is a bus https://3dwarehouse.sketchup.com/model. ... 1a12669bb7 :D

922 views and 60 downloads so I suspect somewhere in the world someone is thinking about building it and after it is proven successful in a third world country we will buy them "off the shelf"

"Limited to 50 kph"? Sounds like they're going to hold up a lot of traffic.


You would think they change the rules to design them with safety standards so they can travel on all roads at similar sppeds to their freight carrying counterparts.

They would only be used in 50kph areas like George street in place of expensive trams at about $500,000 each including a low powered single axle prime mover.

So cheap they could run one a minute for the interest on installing trams.



Denv12
They will not change the rules for 50kph so I doubt that they would for anything faster and semis do have a bit of a bad history of jacknifing.

The main advantage with this sort of arrangement would be that the vehicle could be used as either a prime mover or a bus. For this to be of much use, the company operating the bus would also have to operate a fleet of trucks as well. There were certainly a number of companies that used these types of buses in the past (a rather hazy childhood memory tells me that Arthur H Gillott, who operated the St Ives Bus Services had one, but I could be wrong), but I don't think that you would find, outside any rural centres, companies handling both heavy freight and bus services nowadays.

The proposed bus trailer would, I think, not find any takers within Australia. Would it not be simpler just to use a bus?


Personally I believe the main advantage would be that the trailer could be substantially built to last 30 years with just a new prime whacked under it every ten.

Horses for courses, yes a conventional bus would be much simpler for conventional routes, but where you have extremely heavy loads you need many wheels to take them.

This type of bus would need a conductor for safety reasons thus doubling the labour cost of running it. This would negate any other savings gained. So it would not appeal to operators.

1 minute intervals? how do you propose to load and unload all the passengers and extras in such short intervals?

I cannot see a problem, people would stand behind the line like when a train comes in and stand clear of the ramp as it is closed just like when train doors give a warning.
If you wanted to be extra safe there could be cameras, sensors or even have a LH drive prime mover.

santob
If for example there are half a dozen at the layby end one would leave one minute after the one in front so there would be always one in sight no matter how long they took to load which I guess would only be about one minute anyway with no tickets and the whole side to enter/exit.

However buses would not overtake so if a driver sees another bus right behind him he would skip the next stop unless someone had pressed the buzzer to get off.

The whole idea is to have a very quick trip by skipping many stops while still allowing the stops to be no further than 400m apart.

These would be idea for limited stops service runs like the Transit links between Adelaide,Modbury to Golden Grove Shopping village.They were great services but limited stops which got there quicker.Not that you'd use them on the obahn.

The big problem I have with limited stops is that there are always passengers who want to get on or off between them and I much prefer close stops with buses only stopping where needed.
In actual fact because I live near wide roads, old people and great bus drivers they just stop outside a lot of peoples houses and they all know each other's names with the regular drivers.


Bedford-29
I love that idea but you would have to mix them in with a few trailer buses that could take wheelchairs, bikes, electric scooters and big strollers.

Often I have thought it would be win win to have old buses doing the 555 in George street as it would save a lot from the scrap heap and tourists would come from all over the world to have a ride in them particularly as the safety standards are not as important at 50kph.

I wonder what's in that large "unwindowed" area over the turntable?

Wouldn't be much room for anything. There is the top deck floor above, and the subframe for the coupling below.

But no doubt the Indians would find some way of utilising it.
