Encouraging that there are signs that after enough de-scoping, MX may actually be able to break out of their analysis paralysis.
Reece suggests raising the tracks at Pearson to enable the BEMUs to replace UP Express. Why not raise the platforms? Isn't that what MX has been protecting for?

Well thank God! The use of battery trains are going to save GO a fortune in electrification costs and years of construction time. It's good to now that ML finally decided to listen to me.
How they also plan to implement the battery train recharging system is also superior. It is always better to have 10km here and 10km there of catenary than having every station have a overhead recharge. As frequency increases and they eventually move over , at least for the RER portion, to BEMU and more level boarding, the less time the trains will dwell at each station. By the time the train stops and lifts it's catenary to recharge, the train is already set to move on. There is actually little time for the train to recharge at each station in a meaningful way. Conversely, having, for example, a 10km catenary system on the Lakeshore East and then Lakeshore West means it cannot only recharge during that time but is also not draining the battery for that total 20km. Ideally there should only be one recharging station on each line and that is at terminus stations.

The platforms for the UPX are all 48" above the top of rail - also known as high-level platforms. GO platforms are considerably lower, only about 5" to 10" above the top of rail.
They are too high for BiLevels, but are the right height to have level boarding for most other rolling stock used in North America.

They should be more worried about the platform length than the platform height.
Though surely it's moot with the whole thing slated for redevelopment - they can build what they want when the Skywalk get's knocked down.

Correct me if I'm wrong but when the elevated portions of the UPX went up, didn't they install the place for the catenary to be easily put up? If that is so then a BEMU would be very easy to start up as it could recharge during the elevated section and at Pearson. This would negate having to put up a separate recharging at Union and greatly reduce the amount of charging time needed at Pearson which would allow higher frequencies.
