The two 3,500-hp steeple compound Unaflow steam engines powering the S.S. Badger represent one of the last types of reciprocating marine steam engines. Built by the Skinner Engine Company, most Unaflow engines are single expansion. These feature tandem high- and low-pressure cylinders separated by a common head. The Badger's four Foster-Wheeler Type D marine boilers, which supply 470-psig steam to the engines, are among the last coal-fired marine boilers built.

This is one of three nearly identical pumping stations that drained the Haarlemmermeer (Haarlem Lake), 1849- 52, then continued to maintain the polder's water table for more than 80 years. The Haarlemmermeer area covers 45,000 acres (about 70 square miles) in a triangular region between the cities of Amsterdam, Haarlem, and Leiden.
