STREET RAILWAY JOURNAL. 123 room, with branch flues to two 400-hp triple drum B. & W. practical guarantee against shut-downs is obtained. Two boilers. The boilers are 21 ft. wide and 9 ft. high, andcontain 189 water tubes 4 ins. in diameter. The steamdrums are 23 ft. 3^ ins. long and 42 ins. in diameter. Theboiler plant is built for 160 lbs. steam, and the intentionis ultimately to carry very nearly that pressure. At pres-ent the gage is held at 135 lbs. The furnaces used are designed with three separateshort rocker grates for each boiler, each operated from Blake 14-in. x 8-in x 12-in. single boiler feed pumps havebeen installed and piped, so that each or both can eithersupply a large gravity tank or else pump (i) through theprimary heater, (2) through the auxiliary heater, (3)
