This is a H0e (1:87 Scale) model of a Soviet PV40 750mm Gauge Coach.
I have designed the model to use Roco H0e bogies (the type used on a Austrian 760mm vehicles). Two M2 DIN 934 Nuts should fit into a hexagonal recesses giving something for the Roco bogie retaining screws to screw into. Other bogies could be used and an M2 bolt and nut used to hold them in place.
I can't guarantee that the bogies will fit as I haven't printed the model yet, so for the moment it is availble as Beta project. So if you order a print please let me know how the bogies fit!
I have added small holes to the model to indicate where holes should be drilled for fitting handrails.
