Road trains

Seen this the other day about Denby’s proposed B double.

Can’t really see a reason why a Aussie style road train couldn’t run in the U.K. under certain conditions. Say from 23:00 until 05:00 on motorways just with the big operators having hubs off the side of the motorways at each end?. Possibly with an ■■■■■■ vehicle like wide loads have to get it out into the middle lane passing junctions so Joe Public trying to join the Mway up a slip road in their clio billabong doesn’t have a heart attack finding themselves at the end of a slip road alongside a lorry with six trailers and not knowing what to do.

That was demonstrated about 10years ago and was at the Commercial Motor Show at the NEC in 2007 along with Stan Robinsons version.

maybe because two trailers can do the job of one, and therefore liable to shrink the amount of trailers on our roads, if permission was given, and all the big players put them on the road, it sure would have an impact, a great idea in a transport companies operations ideals, if only used for motorway trunking…huge hubs would have to be built, with direct access from the motorway…who knows if it would work, i suppose it would also increase the carnage on the roads much worse than we have already…not sure if i would approve or not…but there would be drivers willing to drive them for the same money they get now, so long as theyre blinged up…ha ha

This was Denby’s at the NEC

Stan took his around the northern track and showed it only needed an extra foot of side space to make a normal left turn at a normal junction. Stan was well before Debys attempt, Denby added a mid steer on the trailer that’s about it but let’s be honest

Drivers can’t be trusted with a normal set up who’s gonna trust anyone with that

B trains are compromised by the second trailer imposing a load on the axles of the first trailer so pointless for decent gross weigh capacity.While the Stan Robinson example shown was a proper A train type set up.While the double artic is probably excessive for general use here anyway with the Scandinavian type drawbar being the most practical LHV type set up.Which hopefully seems to be the way it might go if the pro rail lobby can be sorted out ( doubtful ).

If you need an ■■■■■■ vehicle it automatically negates the major cost-saving factors of the double; a second driver’s wage and another wagon, albeit a small van rather than a unit.

Hauliers might be able to cash in on these in the short term, but it won’t be long until consignors start asking for rate reductions & some outfit offers to pull a double trailer for the same price as a single one :unamused:

Double decker b-trains, now that sounds like fun.

The fuel consumption doesn’t stay the same at 60-80t gross as at 44t so it couldn’t possibly be done at the ‘same’ rate as at 44t.But likewise it doesn’t increase pro rata with the weight capacity increase in which case why wouldn’t anyone want a more productive more fuel efficient industry. :confused:

In that instance I was really thinking of more than two trailers pulled by the unit.

Pulling 750 tons though would make up for it…youtube.com/watch?v=5UUz1zTZFfU….

Seems to work in NZ and they don’t have any motorways as such (well outside of AKL anyway). Followed a few of these on some of the rural roads and they seemed to manage just fine :slight_smile:

There’s already a dedicated transport sector for that, and it’s completely safe from motorists because it runs seperately from the motorway system.

They’re called railways. :grimacing:

From 3 trucks to two, great for a large company cut the work force by a 3rd over night and the other drivers do 50% more work.

Carryfast:
B trains are compromised by the second trailer imposing a load on the axles of the first trailer so pointless for decent gross weigh capacity.While the Stan Robinson example shown was a proper A train type set up.While the double artic is probably excessive for general use here anyway with the Scandinavian type drawbar being the most practical LHV type set up.Which hopefully seems to be the way it might go if the pro rail lobby can be sorted out ( doubtful ).

You do talk some crap, they have these in Australia , the A and B trailer A , both have tri axle trailers and GVM 90 tonne … there is no impact on the overall load capacity over the B trailers axle.

Let’s get this right.You think that a 9 axle B train has the same gross weight capacity as an 11 axle A train. :unamused: The only reason that the A train,would have the same gross weight as the B train,in that case would be because it’s being artificially limited.While 90 t gross on 9 axles ? :open_mouth: sounds like a joke to me in that regard anyway.

You need to think again about the difference between train weight v combination weight.In which the former is all about the fact that the towed trailer imposes no load on the axles of the towing vehicle/trailer,unlike the B train or close coupled drawbar type. :bulb:

This is gonna be at least a ten pager

Why would 90t gvw on 9 axles be a problem? Many other countries have higher axle weights than the UK, 12R/22.5 doubles could easily raise a trailer axle gross weight from 8t on super singles to 13t alone…
