The Marylander was a Baltimore and Ohio Railroad (B&O) afternoon passenger train between New York City and Washington, D.C., operated by the B&O in partnership with the Reading Railroad and the Central Railroad of New Jersey between Jersey City, New Jersey, and Washington, D.C.. Other intermediate cities served were Philadelphia, Pennsylvania, Wilmington, Delaware, and Baltimore, Maryland. The Marylander‍ '​s origin can be traced back to the late 1890s, when the B&O began its famed Royal Blue Line service between New York and Washington. Operating as #524 northbound and #525 southbound, the trains were called the New York Express and the Washington Express, respectively, in the 1910s and 1920s. The Marylander and its predecessors offered a high level of passenger amenities, such as parlor cars with private drawing rooms, full dining car service, deluxe lounge cars, and onboard radio and telephone service. The Marylander made history in 1948 when it was the first moving train to offer onboard television reception.
