Although the net difference in elevation between Laramieand Evanston not as great as on either of the above namc-<, the grades are long and numerous. Westboundthe schedules vary from to miles an hour IxtweenLaramie and Rawlins, from 35 to miles an hour from. The Firebox Side Sheets and Cro«n Sheet and Combustion Chamber Are All in One Piece, the Throat Sheet Being Welded in as Shown by the Light Line the front barrel course, increasing to 96 in. at the combus-tion chamber course. The firebox measures 126 in. by 96in. at the grate and includes a combustion chamber thelength of which is such as to provide for tubes 22 ft. of the notable features in the design of the boiler is thelocation of the steam dome on the conical course at a pointabove the center of oscillation of the water in the provides a uniform steam space under all conditionsof grade, considerably removed from the zone of violentbuliition over the crown sheet. The firebox is fed by aDuplex stoker and the boiler is fitted with a 48-unit super-heater. The boiler shell courses are of ^4--. 13/16-in. and J,s-in. 381 382 RAILWAY MECHANICAL ENGINEER Vol. 96, No. 7
