A friend bought this unusual part built from MacModels all credit to them for rescuing it. It came with a vertical steel boiler it looks as though it has four cylinders not sure if they would be compound. Apparently it was made by a chap from Stockport. Has any one add any more information ?.


I think you would agree its very ingineous straight out of the pottyengineering stable.

I've no informationto add, but it looks to be a well made contraption. It would be interesting to see it running some day.

A Little more information via a utube comment I'll do a little more online research

"Real versions of this sort of engine were briefly used by American logging companies in an attempt to idiot proof locomotive running gear. I believe they were built mostly if not entirely by Dewey Brothers Locomotive Works and supposedly they worked alright for industrial purposes, although wear and steam tightness of the cylinder pivots were an issue

Finally created an account to post this. I had no idea that such a locomotive had existed.

From The Railway and Locomotive Historical Society Bulletin, No. 112 (APRIL, 1965), pp. 55-63

"Oscillating locomotives were made in a number of sizes in three foot and standard gauges. Most were 0-4-0 saddle tanks, though a few had trailing trucks, fewer still had both trailing and pony trucks and at least one had a complete tender. Among the shortcomings of the oscillating system of propulsion was the high rate of water usage re- gardless of speed and the difficulty of keeping a tight seal between steam box and trunion, particularly in view of the high temperatures and limitations in lubricants and packings of that era. Production of these units stopped about the same time Dewey introduced its new geared locomotive, in 1913."

If you would be willing to sell this I would be very tempted as I am looking for something unusual to showcase one of my bigger gas powered boilers - guaranteed not to sell it on? I ought to call in on Joe more often, if I had I would have bought it.

Another US firm building oscillating cylinder locomotives was Filer & Stowell of Milwaukee. The company eventually focused more on sawmill equipment.

The locomotives varied between 0-4-0 & 0-6-0 wheel arrangements. The cylinder pivoted on a trunnion, coupling to the leading crankpin.
