Northern Arrow was one of the named passenger trains of the Pennsylvania Railroad,[1] starting at Cincinnati, Ohio and ending at Mackinaw City, Michigan.

[2] Carrying the number #519 northbound and #520 southbound, it used the Grand Rapids and Indiana Railroad, a leased subsidiary of the Pennsylvania system.

The train was frequented by northbound travelers to popular Northern Michigan resort destinations north of Grand Rapids, Michigan, such as Petoskey, Bay View (only northbound trains stopped there; it was the stop after Petoskey), Mackinaw City and Mackinac Island.

[4] The Northern Arrow ran express from Grand Rapids to Cadillac (albeit, available for flagstops and Reed City).

The PRR ran a local counterpart from Grand Rapids to Mackinaw City (later cut back to Petoskey)[5] which served the bypassed stations.
