GO Transit Electrification | Metrolinx

I don't think battery-only trains are a good idea especially in such a huge commuter/RER network like GO. Batteries don't work as well or last as long in colder climates and as the batteries drain so does their performance on such things as de/acceleration. Battery-only trains also weigh a ton which offsets much of their advantage in terms of de/acceleration over DMUs and there is the big added cost of having to replace them all when they reach their end of lifecycle. Perhaps battery-only in 20 or 30 years when the technology is far more advanced but not now.

This is why I have always supported a battery-cantenary system. They allow the batteries to be recharged when on route. This is done by having overhead connections and recharging at just the stations themselves as well as regenerative braking. This allows the trains to always be fully charged so they are always operating at peak efficiency. They also require far fewer batteries greatly reducing the weight of the train and when replacement is eventually needed you are having to replace far fewer batteries. There is also no downtime required to recharge and time is money. This is very similar to many battery buses in Europe where the buses recharge only at key transit stops/stations so the buses are always fully charged allowing for top efficiency and being able to ply far longer routes than battery-only buses like what the TTC has.

All this at the same time you get all the advantages of battery-only..................less infrastructure to build and maintain, allowing for easy expansion of electrification without the time and cost of putting more catenary lines up, electric supply not being at the mercy of Mother Nature, and no visual pollution.

And also many of the issues of batteries, should be kept to an absolute minimum
 
What's more at the stations, they don't even need wires or even actual catenary poles on the trains themselves. Seoul is already using WPT.............wireless power transfer. It of course it already has widespread usage in electric buses. Basically you just need the infrastructure of a lamppost so when the train arrives/departs it is recharging without wires. Basically you could have an entire network of electric trains without having to put up a single wire. This also makes the entire system completely secure from the Mother Nature could throw at it.

Such a system has all the independent energy security of a DMU without the high cost of infrastructure and operations of catenary nor the weight and multitude of batteries to replace and none of batteries reduce efficiency when the battery charge starts to decline.
 
More specific timing for encore than what we see in the past. January 22 IO market update posted.

January 2022 Market Update

The January 2022 Market Update affirms Ontario’s historic commitment to modernizing the province’s public assets, including hospitals, highways, public transit, children’s treatment centres, courthouses and correctional facilities.

contract execution by end of q2.
They could announce the winner anytime before then though.

Its amazing how many projects start this year, its felt that things like OnCorr are forever away, and seeing shovels hitting the ground so soon feels really euphoric actually.

Not popping the champagne until I see money flow out the door.
 
Kindly refrain from using the "r" word. It is offensive and unnecessary.
Ok thats ** hydrogen is only marginally better than batteries.
also since when is cost a factor for caltrain? isnt their hsr project like 80 billion at this point?
since when is canenary "expensive"?

They're shaping the narrative to benefit the predetermined outcome. I bet there was lobbying going on behind closed doors

Caltrans is not the Caltrain.

Caltrans is the California Department of Transportation which operates three Amtrak routes in California

Caltrain is commuter rail from SF to San Jose
 
okay thats a rabbit hole brings up so much more questions

The state DOT manages amtrak? i thought amtrak was federally managed?
