The PRR accessed DET from the Ft. Wayne mainline west of Mansfield, Ohio at Toledo Jct.
The line entered Toledo at Walbridge and ran on the east side of the Maumee River, then crossed the river to the west bank where the PRR Summit St. Stn. was located. The line junctioned with the Ann Arbor for a short distance to Alexis and then had trackage rights over the C&O (x-Pere Marquette) to Carlton where an orphan PRR line diverged and went to Delray, then over the Fort St. Union to that station.
The line had 3 roundtrips passenger, the premier was the "Red Arrow" which was the first PRR train to receive diesels as the Fort St. Stn. Viaduct could not take the weight of a K-4. Before diesels, the train stopped, the K cut off, and a station switcher brought the train to the platform.
The line at Bucyrus was the Columbus / Sandusky Branch that x'd the Toledo line at Carruthers. In later years, the Toledo line was abandoned from Toledo Jct. to Carruthers and traffic went via Bucyrus.
