it would just under double it (twice the service, but faster travel times requiring less trains), but given the planned extensions to Niagara, Hamilton, and Bowmanville, I think you would be looking at well more than doubling of service. Introducing 15 minute service on all lines would require a HUGE hiring spree.
The Liberal spending spree is the precursor to a huge cancellation by whichever government takes over (either this year or if the Liberal's survive, in a year or two). I can see the almost exact resemblance to the early '90s where they bought votes by expanding GO (Guelph and Barrie) without costing out the subsidy to run an empty train (or to be more cynical they didn't care since it'd be the next group of MPP's that would have to cancel it).
- Liberals promised with no revenue plan and the NDP had to cancel GO Train Service
- NDP promised with no revenue plan and the Conservatives had to cancel a subway (we are only now building a lower-volume LRT)
- Conservatives promised and spent on Sheppard (Toronto is subsidizing the cost of the opex)
- Liberals are promising and ???
GO transit improvements should be incremental. Just like they have been doing on Lakeshore for the last 40 years. Rush-hour trains, then hourly off-peak, then half-hourly. Finally electrify for quarter-hourly or more often. But each of these only when demand warrants the growth.
Here are my guesses at when the lines should be more frequent:
Rush-hour only, no express - 0 to 3.5 million (Richmond Hill. Barrie at top end so maybe express)
Rush hour and express - 3.5 million to 7.5 million (Stouffville, Kitchener)
Hourly all-day - 7.5 million to 10 million (Milton)
Half-hourly all-day - 10 million to 15 million (Lakeshore East)
Half hourly with electrification (which makes it faster) - 15 million to 17.5 million (Lakeshore West)
Quarter-hourly - 17.5M + (NONE YET)
Other threads people are saying LRT's and not subways because there is no demand and then the supporters here (plus the MPP's) want to throw billions at a bunch of projects where there is not enough demand (yet). The Liberals are promising way too much capex for untested demand that will be a drain on public resources if the supply doesn't show up.
