Paul Ferreira and Andrea Horwath have said that they will electrify the Air Rail Link as it is built, not years afterward, as the Liberals have said they will do and as is currently the plan.
In a press release last week, Ferreira said,
In this election voters have a clear choice between dirty diesel or clean electric trains. The McGuinty Liberals will ram diesel trains through our neighbourhoods…. Under our plan, electric trains will be on track for 2015.
In an article in the Toronto Sun, Horwath said the same thing: if she were premier, she would electrify the trains:
the NDP are proposing speeding the electrification process up — at greater expense — and move quicker on converting GO Transit’s busy Lakeshore and Georgetown corridors to electric trains.
The Liberal government has said that they will install diesel trains before 2015, Metrolinx has said that they will eventually electrify the line, though not for several years after, and only if there is funding.
