The lightly used terminal became even quieter in the years following World War II, with Grand Central serving 26 intercity passenger trains, down from nearly 40 at its busiest. Passenger trains were dropped and service was curtailed, and by 1956 the Chicago Great Western, which as late as 1940 had run six trains per day in and out of Grand Central ceased operating passenger service into Chicago. As a result, by 1963 only ten intercity trains remained, of which six were operated by the Baltimore and Ohio. The number of passengers that used the remaining service shrank proportionately: by 1969, the year the station closed, the station only served an average of 210 passengers per day.
