Named for the many-lettered initials of the participating railroads, it used the following systems from west to east: Major yards on the line included: The freight trains along the middle section of the route were known as Alpha Jets.
For a time during the 1970s, the RDG also symbolled its high-priority connection run from Philadelphia to Rutherford, PA as an Alpha Jet.
Three major sources of traffic for these trains were: In the 1960s and early 1970s, the Alphabet Route partners promoted Alpha Jet service as an alternative to the TOFC service offered by the Pennsylvania Railroad (and then the Penn Central, after the Pennsylvania-New York Central merger in 1968) between Philadelphia and Chicago.
Although this did not seem competitive, much of the 11-hour difference was due to departures and arrivals around midnight for the Pennsylvania service, whereas many shippers did not send and receive shipments during the night and thus could accept a mid-evening departure and a mid-morning arrival, as the Alpha Jet service could provide.
Alpha Jet service was de-emphasized in the late 1970s and eventually ended by the early 1980s as the WM was fully integrated into the Chessie System (B&O and C&O), later to become CSX, which was and remains a major competitor of the N&W, later Norfolk Southern.
