Re: Chilean Minimum gauge mine steam loco ?

I have seen a gauge of 1'-8.5" quoted for this engine, but without Black Hawthorn's works list, or being there with a tape measure, that is difficult to confirm; single driver engines of this size are not unknown, Barclays produced some. The nature of these things is that the engines are a very...

Re: North American Minimum Gauge Industrial Locomotives

I have found a photo of one of the Hunt engines, the Bridgeport Malleable Iron Co No 3 of 1913

scroll down to the bottom of p9 and there is a Baldwin works photo.

Re: Twining 0-4-2 loco

There is a drawing of an earlier proposal of Twining's for a slightly larger 0-4-2 tender engine in "Katie's Other Sisters" by Stan Buck, which refers to a 1940 15in gauge proposal, which I presume this is an artist's impression of.

Maybe there is something waiting to be discovered!

My immediate reaction on seeing this was to cite cases like the GNR Atlantics and Churchward's Counties notoriously rough riding on account of their short fixed wheelbases and hefty piston thrusts from their outside cylinders, the County had 18 x 30 cylinders as the Saints did.

There is always the Greenly Fairlie; I have seen a schematic for a 15in one (possibly for the R&ER) but I can't remember where! As I recall it was a 2-6-4 or 2-8-4, with the pivot on the power bogie quite far forward, and the driver sat over the non-powered one

only real difference from the earlier engines is the loco type boiler That and the shorter cab, chimney and dropped footplate, the disk wheels opposed to the spoked. As you say, the loading gauge being so tight - Baker & Civil give the height as 6' 6-3/4" - exactly 2m if you work in such u...

This is the post-war version, the only real difference from the earlier engines is the loco type boiler, apparently dictated by the poor quality of the coal to be used, manifesting itself in the much higher pitch and not-so-elegant dome cover.

I have seen both 2ft and 1m quoted, though the latter seems impossible. Apparently the engine was built for mine service and so would have been to the gauge of the mine's track. http://www.flickr.com/photos/42417027@N05/4539881289/ Shows a drawing of the engine as at the exhibition, and another of t...

Very glad to have been of help! When I did MSTS models for Polar Bear and Sea Lion I was struck by how much similarity there is between them and the tiny 0-4-0ST, despite their very different appearance.

There's a little Bagnall there, apparently supplied to Copenhagen gasworks. I will check in the book tomorrow, but it looks a similar size to the Brede engines. The (locomotive) boiler may be original, but I am fairly sure that the extended smokebox is not.

There was a Roy Link drawing in the NG&IRMR, where it was referred to as the 20HP class (I think the Mercedes was bigger), but I can't remember which one it was. It was the later one, with Bagnall-Price gear.

I have just looked up the article in "The Narrow Gauge", Issue 60 Spring 1972, which also lists another line in nearby Spetisbury, which was operated by a driverless petrol trolley, controlled by the same kind of trips as used by clockwork O gauge tinplate trains.
