Yes. Entire subway systems (including NYCs) were driven by MG sets
at one point. The original NYC subway power plant was DC, with giant
reciprocating steam engines, and operated into the 1950s. One of the
20' long pistons can be seen in the Smithsonian. When the steam
engines were replaced, MG sets replaced them, to produce the 600VDC
used by the subway system. I assume they've upgraded since the 1950s.
But do we really care?
