One of the keys to my mountain railway section looking the part is the use of HOn3 track which is 10.5mm gauge which equates to 1’7.5″ gauge in really life which is what narrow gauge rack railways usually are.
HOn3 isn’t all that common in the UK and coupled with me being a skinflint I have set about tackling the rolling stock in the most cost effective way possible.
Ad part of their expanding range of 009 products, Peco now produce ready to assemble bogies in “passenger” style and arch bar style. I decided that my carriage will be slightly industrial and run on arch bar bogies so I procured a set of them and then a set of HOn3 wheels.
Despite there being only 1.5mm between the two gauges, the treads of HOn3 wheels tend to be larger than 009. Thus the wheels wouldn’t fit in the bogies. However with judicious use of a file to file the inside faces of the moulded plastic bogies, and a 1mm drill to deepen the axle boxes, the bogies can be made to accommodate the HOn3 wheels.
