This is a H0 scale model of Cairo & Kanawha RR boxcar no.5. The original was 3 foot gauge, but was small enough to be at home on a 2 foot or 30 inch gauge line. Some 1mm thick (0.040") plastic card is needed for the roof, plus wheels, couplers and detail parts to complete. See instructions .
Now with separate brake gear, giving the choice of air,vacuum or no automatic brake. The brake parts can be found inside the body.
The last picture shows the positions where the parts are to be fitted. It is for reference only, don't fit both parts!
This version is optimised for printing in Frosted Ultra Detail. The styrups have added support to protect them in transit, this needs removing for finishing. See pictures.
The interior floor is omitted to reduce cost, this can be made from some styrene sheet (plastic card). Cutting it in half will make fitting it easier.
