January 30, 2018, was sunny (but cold) in New York City until mid-afternoon, when a snow squall moved in and created a micro blizzard. Within minutes, heavy snow fell and a strong wind blew the flakes horizontally. Amid this sudden snowscape, Metro-North Railroad train 870 passed through Harlem in New York City as it makes its way from Poughkeepsie to Grand Central Terminal, just a few miles ahead. Its locomotive, MNCR P32AC-DM 230, wears a coating of snow kicked up and stuck to its face, typical of the rear of a train in these conditions.
Meanwhile, an outbound train, number 843 (Grand Central Terminal to Poughkeepsie), powered by MNCR P32AC-DM 218 has emerged from the subterranean line out of GCT and is approaching its first stop at Harlem-125th Street Station. This train has not yet been in the elements more than a half-mile or so, but the front of 218 will surely gather more snow and ice as the train heads north.
