There is a $4M study being drafted right now, looking at electrification of the GO Transit System, in Toronto Ontario.
Last week, they released a draft for comment.
With respect to the growth of service, in my part of town, they had this to say:
“On the Lakeshore East line, the number of trains arriving into Union Station in the 3?hour AM peak is
assumed to increase from 12 to 17 by 2021. Within the peak hour (0730?0830) there will be 9 trains
arriving into Union Station, representing a 6 to 7?minute headway. There will also be a significant
increase in the off?peak service, with an expansion from 1 to 2 trains per hour in each direction.”
