The F&C website is constructed such that it can only receive questions from the USA (probably deliberate) Can anyone ask on my behalf what trucks they recommend for the Dairymans league and Central Vermont. Wood milk cars. I have had my kits so long they recommend a Central valley truck.
It was mentioned recently that the cars need extra detail to be accurate models, please could anyone tell me what extras they need.

More likely because of poor web design. For a LONG time, it was not Mac compatible. 

Philip:

I can't find parts of my instructions for the CV car, and I'm not sure I would rely on them very much if I could.  And I have not yet built my kit, so caveat emptor.

The trucks are a pretty conventional Commonwealth express truck, with a 7-0 wheelbase.  Precision Scale #32480 is a very good match, and the Athearn 90383 trucks are pretty close as well.  In either case, the wheels should be 36" AFAIK.

The other details that jump out at me are the steam and signal hoses for passengers service, as well as the buffer over the coupler.  The attached builder's photo, courtly of John Nehrich and the NEB&W website show these.  It also shows a club-style ratchet brake as-built.  Some later photos indicate a conventional stemwinder brake, but I have no idea when they might have been swapped in.

Hope this helps.  I'm afraid I have nothing on the Dairyman's cars.

If you are interested in using Central Valley Trucks, I may what you need.  They were the gold standard back in the day, and while not as detailed as some of the newer trucks on the market, the rolling characteristics are still quite good.

Hallmark offered these trucks also. 7' wheelbase, 36" wheels. I have a few sets.
