Dublin was a station stop on the Pere Marquette Petoskey Subdivision in Manistee County, about four miles north of the Lake County line. It was next to Florence and the PM appears to have shared a depot between Dublin and Florence.

[PM45} notes that Dublin was so named because the railroad "doubled" (separated their trains in half) for transport up the steep 1.6% grade here.
