These box cars were the first mass produced HO scale Chinese freight car, although 'mass-produced' may be too strong a term. The first run sold out fairly quickly, considering that Chinese model railways was still in its infancy at this stage. A second run followed about a year later, although asides from the road numbers and repositioning of the description labels on the box, they were more or less the same.
In late April 2011, Bachmann China announced a third run of these cars, with two new road numbers per livery. The new P64's are also lettered as 'P64AK' - the K denoting fast service type bogies (and, yes, they're equipped with said bogies). Unfortunately, they've also equipped the latter run with pizza cutter wheels.
The body is a one piece casting, with everything apart from end ladders/footsteps grab irons on the roof and brake gear, molded on to it. Unfortunately, the doors are also part of the body shell, so therefore can't be positioned in an open positon, unless you're up for some major kitbashing. Asides from this, the models are very well done. The undercarriage has separately applied braking gear, although most of this is lost when the car is on the rails. However, if you're one of those who experience frequent derailments, you should find this to be rather nice. The basic body style is very well reproduced and the paint is very evenly applied. Lettering is very sharp and clear. My main criticism is with the green color on the P65's which looks like it was pulled from a nuclear reactor. I've yet to see a P65 with anything remotely bright as Bachmann's interpretation! The third run P65's are still being being turned out in the same green color.
These cars are nicely weighted and roll very freely. The metal wheels are low profile (except third production run) and roll over just about any HO scale track you can throw at them. (Bachmann - we really, really miss these)
The Bachmann EZ-mate couplers can be replaced with Kadee #5/58/158 couplers.
These cars tend to sell out quickly. While they have a few minor deficiencies, they are very worthy cars for any 1990+ prototype Chinese layout.
