With its large tractive effort at speeds of 40 and 45 milesper hour it would seem to be also well adapted to fast freightservice on moderate grades. Twenty of these engines have recently been delivered by thebuilders to the St. Louis &amp; San Francisco, being built entirelyto the railway companys specifications. There are included anumber of new features first introduced into locomotive practicein this country by the American Locomotive Company, andwhich are being quite extensively adopted and specified by thevarious roads throughout the country. Among these will be no-ticed the outside steam pipes, the self-centering guide for thevalve stem and the outside bearing radial truck with floating yokespring guide and universal flexible spring supports. 190 AMERICAN ENGINEER.

Assuming that the locomotivewill deliver a tractive effort of 14,660 lbs. at 50 miles per hour,as shown in the above talile, this would be equivalent to an in-dicated horse power of 1,950. At a rate of steam consumptionof 21.6 lbs. per indicated horse power per hour, a conservativeaverage figure for a superheater engine, even when not workedto its capacity, and including steam used in cylinders and airpumps and losses through safety valves, this would mean a wa-ter evaporation of 42,206 lbs., or 11.4 lbs. per sq. ft. of heatingsurface per hour. Except with a poor grade of coal, the boilersliould be able to maintain this rate of evaporation at 175 lbs.boiler pressure without the least difficulty.
