The SmartTrack transit plan Mayor John Tory was elected on, is apparently becoming smaller and cheaper but with the promise of more frequent service.

A Globe and Mail report says staff with the City of Toronto and the regional transit agency Metrolinx have been working on how to integrate SmartTrack with plans to expand GO Transit rail service.

Once details are finalized, Metrolinx staff are expected to recommend adding only four or five new stations along the Kitchener and Stoufville corridors, and light rapid transit, instead of heavy rail, along Eglinton Avenue West to Pearson Airport.

The plan originally called for 3 stations in that stretch, but with LRT, staff are looking at between 6 and 17 stations.

The latest estimate is that the proposed integration of SmartTrack would add between $2-billion and $3.5-billion to the cost of the existing GO plans.
