As an example of a very compact source of tractive effort theswitching locomotive, shown in the illustration, and recently com-pleted by the Baldwin Locomotive Works for the Western Rail-way of Havana, Ltd., is very interesting. It provides a tractiveeffort of practically 32,000 lbs. in a machine which occupies butlittle over 33 ft. of totai track space and is carried on a wheel In other respects the details of the boiler and running gearare not unusual. Parts, as far as possible, have been made in-terchangeable with those on previous engines for the same road,many of which were built by these works. The general dimensions, weights and ratios are given in thefollowing table; GENERAL DATA. Gauge i ft. 8A m. Service Switching Fuel Coal Tractive effort 31,930 lbs.

This gives a locomotive that is capableof going into all kinds of odd corners over poorly ballastedtrack and able to handle a good load even on a stiff grade underthose conditions. As can be seen, it is of the tank type, an ar-rangement which for a switching locomotive has many advan-tages and, under the special conditions that such a design wouldoperate, very few disadvantages. The details of construction are markedly simple Walscjiaert valve gear, with a slide valve, has been em-ployed, an arrangement having been designed which is excep-tionally free from complications and of very few parts. Thevalves are set with a constant lead of 3/16 of an inch. It wasnecessary to cut away the bottom of the side tanks to clear thelift shaft arms, but a suitable arrangement of equalizing pipeshas been f
