North Station was originally opened in 1893 to replace four older stations in the same area used by the Boston & Maine and the Fitchburg Railroads (B&M had previously absorbed the Eastern and Boston & Lowell railroads, and later absorbed the Fitchburg as well). In 1928 the station headhouse was demolished to make way for the Boston Garden sports arena. The current North Station opened in 1995 with the completion of the Fleet Center (now TD Garden), built 9 inches north of the old Boston Garden. The current station has twelve tracks, but only the first ten are currently useable; the last two were never connected to the approach tracks. Besides the MBTA, Amtrak’s Downeaster to Portland, Maine also terminates at North Station.
