Equipment Information

Milwaukee Electric 12 is a portable substation constructed in that interurban line’s Cold Spring Shops. Electric railways used substations to step down commercial high-voltage alternating current (AC) to the 600-volt direct current (DC) transmitted via the trolley wire. Portable substations like number 12 could be used when a fixed substation failed or was down for maintenance.
