Going to move this to a more relevant thread....

Battery technologies just kinda grew helter skelter, and we are seeing more and more of the impact as time progresses, along with the economics of geopolitics.
That same energy system can go to green hydrogen production - no real need for the natural gas option if properly configured / installed / operated.
Reliability of battery systems could well be - again I have no numbers.
This is what a proper trial is meant to prove out.
But unfortunately - to be a bit nasty - there have been several widely reported difficulties with various manufacturers' battery systems in cars and suvs lately, as the technology ages into more massive production and matures.
True - this is cars and suvs, where they are trying to reduce costs and margins to an extreme, but still.....
Good discussion, but I am open to having it move elsewhere than the VIA thread if anyone wishes to suggest where.
Thx.

In any other city, the Trillium Corridor would be twin tracked and electrified and we wouldn't be having this discussion. The best solution to any moderate frequency urban or suburban rail corridor is electrification. Battery or fuel cells are at best a compromise solution. Full electrification has the lowest operating cost, the least disruption (no refuelling time, lower maintenance) and the highest reliability (fewer components and no novel technology).
Second to the above is battery-electric. And that's largely because there's no need to buildout a whole storage and distribution infrastructure, as you would have to for hydrogen. Installing charging gantries at the terminii is relatively easy. Hooking them up to the grid is not an issue.
Hydrogen fuel cells have a very specific application which really doesn't apply to the Trillium Line. Hydrogen fuel cells are great for long, low frequency routes where batteries can't provide enough range and the cost of electrification is not justified because of low frequency. If you want to run a train 95 km through the countryside, a few times a day, hydrogen fuel cells might make sense. A 24 km suburban rail line running 5-6 trains per hour in each direction? Full electrification or battery with charging at the terminii is more sensible.
