One line, four names: the Grand Trunk succession whole

1873 TO NOVEMBER 2026

The line's ownership reads as a ladder, and every rung is dated. Peninsular Railway (to the consolidation of 15 August 1873); Chicago and Lake Huron Railroad (1873–1879); the Grand Trunk's purchase and the Chicago and Grand Trunk Railway, which incorporated the entire Port Huron–Chicago line in 1880 — the archival record shows the property transferred to the system's Michigan and Indiana railway companies on 13 March 1880, in the same reorganization season; the Grand Trunk Western Railway of 1900, under which the Grand Trunk united the Chicago and Grand Trunk and all its Michigan, Illinois and Indiana lines in one American subsidiary (restyled Grand Trunk Western Railroad), with the Canadian parent's own collapse and absorption into Canadian National in 1923 carrying the American lines with it; and the modern form, in which the GTW has stood since a 1971 corporate restructuring under CN's Grand Trunk Corporation, its routes administered as part of CN's Michigan Division. The track through Granger has therefore been, without ever moving, a Peninsular local line, a Grand Trunk international main line, and a Canadian National transcontinental freight artery — the same diagonal the Peninsular's graders cut across Harris Prairie in 1871.

Its operating form in the heavy years is fixed by the federal record. The Interstate Commerce Commission's report on the derailment at South Bend of 28 April 1932 describes this line as the South Bend Subdivision of the Chicago Division, extending between Battle Creek, Mich., and Griffith, Ind., a distance of 140.56 miles, and states of the track at the accident site — the same construction that ran through Granger — "this is a double-track line": two main tracks, worked by timetable and train order, carrying the Chicago–Toronto passenger fleet and the freight of the system. The subdivision's boundaries have shifted across the timetables (the 1984 employee timetable works the South Bend Subdivision under the Battle Creek dispatcher, Elsdon to Battle Creek), but the identity has not: it is CN's South Bend Subdivision today, a freight-only main line whose through trains pass the village site without stopping, as they have since the passenger era closed. One South Bend-side change belongs here at boundary size: in 1949 the Grand Trunk Western shifted its through South Bend route onto joint trackage with the New York Central, stubbing the old main line east of downtown into an industrial spur — a South Bend rearrangement that left the Granger alignment, east of the city, exactly where the Peninsular put it.
