    I picked up a Bachmann On30 Colorado & Southern carriage at a second-hand stall at the Epping MRC show at Rose Hill last week.

    I've heard lots of tales of narrow-gauge from standard gauge equipment, but I wondered if I could standard-gauge a narrow-gauge item. So, I started with a set of standard gauge bogies. These are NSWGR 2AA type, found under numerous passenger carriages. The trouble here is that the Bachmann body works out at a scale 7ft wide, and it does rather look like a kid wearing his dad's work-boots.

    I took a closer look at some prototype photos of similar carriages found in Australia and I noted that the Bachmann bogies looked rather similar to those found under the NSWGR KA "Tramcar" from the 1880s. The last example was largely destroyed by an arson attack in 1993, but the remains are somewhere up in the mountains now. So I borrowed some wheel sets from Athearn O gauge bogies, and modified one bogie to standard gauge. The wheels are about 18mm diameter, which seems to suit this carriage much more nicely than the 21mm standard wagon wheels in the 2AA bogies:

    The locomotive in both shots is a brass Manning Wardle H class, produced as a limited run some years ago. There was talk of a re-run but they failed to reach the required EOIs for an order. Numbered as 1021 of the NSWGR, built by Manning Wardle in 1916 and retired from service in 1970. She was also hired out to a private coal railway for a time, so I might be able to "imagineer" a private line in NSW, Australia with an odd collection of rolling stock.

    The KA Tramcar. I will be scratch-building one of these soon.

    Both bogies converted and it now sits about 1mm higher which seems to give better wheel clearances.

    By the way, the carriage measures in 7mm scale 28 ft over body, 32ft over headstocks, 7ft wide and approx. 11ft tall from rail level with these bogies.

    I'll be doing a few sneaky things to increase the height of the carriage. This mock-up shows how I will increase the height by nearly a scale foot. Though, I will probably ditch the clerestory roof for a simple arc shape.

    Someone mentioned San Juan car co. kit parts. I did have a set of ends and sides somewhere. The ends are no-where to be seen, but the sides turned up after a short rummage in my garage. They're about 7 scale feet longer than the Bachmann carriage sides. Of course, they were significantly cheaper, but the Bachmann coach was complete with bogies, which turn out to be perfectly convertible to standard gauge!

    Nice work Martin
    With the wheels and the bogie adjustments to standard gauge you are well on the way to a uniquely different coach it will certainly suit the early era modelling period you enjoy.

    I’ve done a mod on the Bachman coach Turing it into a centre door loader with elliptic roof and no balcony ends.
    Can’t find a photo of it at the moment will post up if I find it the model is currently packed up in storage I think.

    Ok so I turn around from the modelling bench and see in the corner of my big glass cabinet the On30 coach mentioned above hiding behind a loco. So your in luck Martin photo below
    And I painted it NSWGR Tuscan with a buff line to give you an idea of the inspiration I was using when I made it
    I’ve always thought I should have made it with a Mansard Roof like a NSWGR L or R car for even more resemblance to the NSW coach’s

    Just got my hands to a set of construction drawings for the KA Tramcar. 30ft over the body, 35ft over headstocks. I'm surprised at how wide the body is at 8'10" over the corner-posts on the main body, and 9'0" over the steps.
