Soon the Washington-to-Atlanta routing expanded via the West Point Route from Atlanta to Montgomery and the Louisville and Nashville Railroad from Montgomery to New Orleans, via Mobile. The route was then extended to New York (Jersey City before 1910) along the Pennsylvania Railroad's northeastern trunk line, now Northeast Corridor, via a connection in Washington with the "Congressional Limited". Scheduled time for the New York-to-New Orleans run was advertised as a "40-hour, unprecedented" trip. Because of the popularity of this service, the "Vestibule" became a solid train of walk-through cars between New York and New Orleans. It also carried the first dining cars to operate between those two cities.
