Wiggle... flatbed?

Never? Most of ours were b-trains, but we had a few tandems (although I understand far less popular in the US).

As for their purpose; same as any other... haul more freight. Lots of crane moves. They're very popular hauling lumber.

The second last one is what happens when you put 90,000 lbs of counterweight on half a b-train on a sand sub-base.

The last one is the worst POS trailer I've ever hauled... popular with hay haulers.

 

Seen lots in CA hauling tomatoes.

 

We have a supplier that pulls double 48 flatbeds on the Indiana Toll road/Ohio Turnpike, from the Youngstown Ohio area, to Elkhart Indiana. Driver pulls them across, then delivers off both, one at a time.

 

This was Dads setup new in 1988 in Ohio. A-trains. You could dock both trailers for tow motor load. But the big reason was to double out of a steel mill.


Get two, or four manifests and take each trailer in separate. Two coils on the first trailer, and leave. Then load 2 coils on the second. Go down the street and hook them up for a midnight ride. They are very popular in Oh,Pa,Mi,In,Ky. But mostly Btrains with every kind of axle configuration you can imagine.

 

This boy backed up a b train next to me last night.



B train conestogas ?

 

B's back up pretty easy.

 

Difference between a A train and a B train?

See lots of doubles in Michigan because of the bridge laws.
