In this table the num-ber of square feet of heating surface in tubes from 7 to 15feet long and from 1% to 2i^ inches in diameter are given, alsothe same information for each inch up to a foot In length, andfor the fraction of an inch. In using the table, add togetherthe heating surface for the feet, inches and fraction of an inchfor one tube and multiply by the number of tubes. SEPTEMBER. 1899. AMERICAN ENGINEER AND RAILROAD JOURNAL 293. Ten-Wheel Passenger Locomotive—0. & R, Q. Ry.—With Piston by The Brooks Locomotive Works. TEN-WHEEL PASSENGER LOCOMOTIVES. Denver & Rio Grande. Brooks Locomotive Works, Builders. The accompanying engraving is from a photograph of oneof 10 heavy 10-wheel passenger locomotives recently built bythe Brooks Locomotive Works for the Denver & Rio engines have 21 by 26 in. cylinders, with 10-in. pistonvalves, and the boilers will carry a pressure of 210 pounds persquare inch, which we believe is the highest pressure carriedon single expansion engines in American practice. The weightill working order is 160,000 pounds, 124,000 pounds being onthe driving wheels. The boiler is of the extended wagon top,radial stayed type, with a total heating surface of 2,422 squarefeet. The grate area is square feet, the firebox being109 by 41 inches. The engines have Westinghouse air pumpsand tender brakes and New York driver brakes.
