The pic I posted wasn't Bachmann's Thomas Well Wagon, it was Bachmann Branchline's.

Sorry, should have made that more clear.
So I am familiar enough to know that the van with the triangle roof is the salt wagon and the other van with openings on the sides is the cattle truck and we all know what the coal wagon is...

The tanker explains itself and the 6 ton wagon is the 1 plank truck right?
