They perform 198 separate journeysdaily and carry 6,700 passengers on the average during the sameperiod. The cars are of two separate types, and one of thelatest built (in 1906) is illustrated Herewith. This car is propelled by steam supplied by a boiler of peculiarconstruction, which is shown in one of the illustrations (Fig. 2).The fire box is in the center and there are two barrels with sepa-rate nests of flues and smoke boxes, one on either side of thefire box. The smoke boxes connect by uptakes to a single stack April, 1907. AMERICAN ENGINEER AND RAILROAD JOURNAL. 196.

The smokeboxes are fitted with hinged doors, one of which can be seen onthe outside of the car. Each barrel contains 232-ij^-in. tubes, 27in. long, giving a tube heating surface of sq. ft., whichtogether with the fire box heating surface of , gives a totalheating surface of sq. ft., the grate area being 10 sq. ft. Steam is supplied at 180 lbs. pressure to a pair of 10^2 x These drive on the forward wheel of the truck, whichhas a diameter of 42 ins. The slide valves are set vertically onthe inside of the cylinders and are operated by a Stephensonlink motion. The trailing wheel of this truck is 34 ins. in di-ameter, and the whole truck with the boiler and including thecab, really forms a small locomotive, and whi
