The full version of the Benefits Case Analysis for the Yonge Subway extension to Richmond Hill is now available online. I will comment on it at greater length when I have the time to do so.
Notable in this report is the acknowledgement of the effect of this extension on the existing subway system and especially Bloor-Yonge Station. There are conflicting remerks in the BCA regarding the degree to which improved service on GO Transit to Richmond Hill can divert riding from the subway line. A major issue here is that the implementation of very frequent all-day “Express Rail” GO service to Richmond Hill is not contemplated in the Metrolinx plan until 2031, long after a subway extension would open.
Detailed work on a number of related proposals will continue, and Metrolinx expects that a full evaluation will be available in late 2010.
