Opening of the First Rail Line

This line, now part of the Finnish Main Line, was built to the broad 1,524 mm gauge used in Imperial Russia. The opening marked the beginning of the Finnish railway network. The supplied passage dates the opening to January 31, 1862; the legacy row and event scope instead state March 17, 1862. Because the scope admits a specific opening date only where retrieved passages state it, and no supplied passage supports March 17, the passage date is retained and the conflicting March 17 date is recorded as an explicit discrepancy rather than silently discarded.
