Model of a locomotive engine for running on the ice; scale one-eighth full size.
A model showing the general construction of an ICE LOCOMOTIVE sent to Russia last autumn, which has been successfully at work during the winter on the river Neva, between Cronstadt and St. Petersburg, conveying passengers and goods.
The full-size engine, of which a photograph is exhibited, was constructed by Messrs. Neilson and Co. of Glasgow, and bids fair to be a very useful agent, on the great rivers, and inland seas of Russia in transporting goods, etc. when the ordinary navigation is closed. The engine when in working trim weighs about 12 tons, has cylinders of 10 in. diameter by 22 in. stroke, with driving wheels of 5 ft. diameter; these wheels are studded with steel spikes to obtain the necessary adhesion. The steering of the engine is accomplished, by shifting the front sledges in the required direction by means of an endless screw and worm wheel, working a pinion, gearing into a circular rack bolted to the sledge.
