The line was opened in two sections: from
Seregno to
Carnate on 24 September 1888, and from Carnate to
Ponte San Pietro on 1 July 1889 with the completion of the
San Michele Bridge across the
Adda River. From Ponte San Pietro to Bergamo the line used the existing track of the
line to Lecco, dating to 1863. The section between Carnate and Bergamo is used by the regional service of the Milan–Bergamo railway. == See also ==
