I will correct you where necessary
A lot of people seem to be under estimating the scope of work and money that would be needed to electrify the network. We're talking about entire tracks being ripped up. Electric trains need concrete ties to ride on. Not the wooden ties currently being used..
No, you can use wooden ties. Where did you hear this?

Frieght trains wold not be able to share the same tracks with electric GO tains.
100% of the electrification will be done on Metrolinx owned track, where freight does not typically go. When it does need to use these tracks, on the rare occasion, freight can use the line without issue. The overhead wires will accommodate this, as per the December 5th, 2014 Metrolinx meeting.
Union station would need to be rebuilt to accommodate electric trains.
I don't think the politicians are very serious about electrifying the network, because they're currently rebuilding Union station without planning for future electric trains.
Where did you hear this? Union was upgraded with electrification in mind.
They're purchasing new bi-level cab cars for the existing diesel trains. The provincial government is spending a lot of money updating the infrastructure for diesel trains.
Its still needed after electrification. Electrification will only work in certain areas, a lot of the fringe stations in the network will still be serviced by diesel for decades to come. Do you think the bi-levels we currently have will last forever? Some of them are over 40 years old.
Honestly, in my opinion I don't understand why everyone is in a hurry to electrify the system. I think the existing diesel system can still be vastly improved upon.
No it cannot, as we are seeing larger increase in development in the inner GTA. This is best serviced by fast accelerating EMU electric trains. The BiLevels were designed for high occupancy in peak periods because they shared track with freight; there are only certain times you could slot in trains to operate. Now that Metrolinx owns the lines, and the inner GTA is seeing huge growth, EMU trains are needed to properly service it.
Can a diesel train do this?
The advantages are immediately obvious.
In the end, electrification of the GO network will be a breeze compared to any other options, like tunnelling and building a subway.
The first phase of the Kitchener Line will probably start in 2018 and complete in 2020, about the same time the Eglinton LRT will be done, which started in 2010!!!
