Hmmm, I think this is the first time I've seen a train station with a water station. the Delaware, Lackawanna & Western Railroad station at Norwich, New York, circa 1900

Standing near the tracks is the railroad 'watch tower' for what was once the 'Delaware, Lackawanna, and Western Railroad.'

Once upon a time, there were "levermen." Their job was to manually switch which railroad tracks a train was using. They would work these levers from above the tracks in the "watch tower," which would also let them keep an eye on the traffic (when tracks would cross the road).

Unfortunately, in the 1930s levermen started to be replaced - Technology allowed the companies to switch tracks by remote control (from a traffic center that could 'remotely control' multiple towers). By the 1980s almost every watch tower in America was obsolete, and most of the watch towers have been torn down after sitting empty for decades.
