30m roadtrain to be tested in Sweden

[G-CPTN]

How will a longer trailer be transported to the test site? Will it require an STGO permit?

Loads up to 30.0 metres long can be moved under STGO so imagine this how it would be done - where?

13th August 2008:-

Tinkler met with Stephen Fidler, head of freight logistics at the DfT, to present his idea for a trailer that is 950mm longer than standard, with a steering rear axle to maintain the current turning circle. He says that Stobart has now asked trailer firm SDC to build a prototype for off-road testing.

What's the maximum length in great britain?

In sweden it is 24 or 25.25 as I wrote earlier.
If you want to see lots of 25.25 of different types, just go to Värtan och Stockholms Frihamn (Freeport) when a ship from Finland or the baltic countries arrive.

Looks like a B-double pulled with a dolly

Ah, missed that article. Thanks.
Maximum lenght for buses in Sweden is
12 m for buses with 2 axles
15 m for buses with 3 axles
18 m for articulated buses
24 m for double articulated buses

The resumee about STGO in http://en.wikipedia.org/wiki/Semi-tr...United_Kingdom suggests that an escort is required.
Whilst some extreme vehicles do usually have an accompanying vehicle I don't think that this is universal?

Most UK trailers are 45 feet (13.5 meters) long and, dependent on the position of the fifth wheel and kingpin, a coupled tractor unit and trailer will have a combined length of between 50 and 55 feet (15.25 and 16.75 meters). Although the Construction and Use Regulations allow a maximum rigid length of 60 feet (18.2 meters), this combined with a shallow kingpin and fifth wheel set close to the rear of the tractor unit can give an overall length of around 75 feet (22.75 meters), although combinations of this length are usually used only to carry steel or concrete beams. Providing certain requirements are fulfilled, a Special Types General Order (STGO) allows for vehicles of any size or weight to travel on UK roads. However, in practice any such vehicle has to travel by a route authorised by the Department of Transport and move under escort. The escort of abnormal loads in the UK is now predominantly carried out by private companies, but extremely large or heavy loads that require road closures must still be escorted by the police.

So what is the maximum (none STGO) length that could be regularly used for general haulage? 60ft trailer plus 15 ft tractor?
What about a 'standard' 45 ft trailer with a long-wheelbase conventional tractor?

Phew! My head-bone hurts after that . . .

In sweden there are no police escorts of heavy or long vehicles. The escort is carried out with private companys, and if a road needs to be closed, a Vägtransportledare (Road Transport Leader) is allowed to do that.
