Micro Trains 1017s will fit the B-mann passenger cars. You will lose the lights unless you substitute live wheelsets. I do not know if the B-mann wheels will fit into the MT truck frames.
As
@nickelplate759 correctly indicates, you can use the existing trucks. You simply replace the Rapido with 133/1134. The 1134 has a longer shank if you are going to run these things around really sharp curves. The conversion is not difficult. The instructions with the kit are good; follow them. One thing that you
MUST buy if you are going to work with 1133/1134 is the MT coupler tweezers. They are not expensive and will make the job
so much easier. The 1133/1134 is almost universal for older Bachpersonn equipment. Work with an Optivisor or magnifying lamp. Some of the newer Bachmanns also take 1133/1134 but other take different.
Another solution is B-mann's own dummy knuckle couplers or UniMates.
