Allthough I have Accumates on some of my cars, I prefer MicroTrains. Accumates have had several problems over the years, trip pins falling out, couplers just falling apart, etc. Under any real load, the couplers will come apart. To help solve that, I ACC the pocket shut on any new cars I buy with Accumates on them. However, there's still the problem of distance between cars to overcome. At this time, I don't believe there is a short shank Accumate coupler available.
