1995 October 26 Line reopened for rush-hour revenue service, after several delays. Rush-hour service was originally to resume August 28, and full-time service September 18.The new trains were an immediate hit with passengers, who were fed up with breakdowns and either roasting or freezing in the old trains. At first, the only apparent problems were with the end doors on some cars not closing properly. Bombardier technicians rode shotgun on some trips, to fix any problems. Full service resumed December 1, after completion of fencing along the line.
