Berkshire Improvements—Mixed-Pressure Turbines andEngine-Type Generator at East Street Station,Pittsfield mote com nil for operating oil circuit-breakers in a new transformer station adjacent to the generating plant. The plant is located about 1 mile outside the businesscenter of Pittsfield and adjacent to the operating headquar-ters and principal carhotise and repair shop of the System. Coal is delivered by gravity to a storage yard of 8000-ton A/AY JOURNAL 1171 capacity paralleling the main line of the Boston & AlbanyRailroad. The station is 144 ft. long over all and 104 , and in addition to the four generating units men-tioned above contains six 380-hp boilers hand-fired andequipped with Reagan grates, Westinghouse-LeBlanc con-densers for service with the mixed-pressure turbines and
