GO Transit Electrification | Metrolinx

However there may be issues with 25kv infrastructure that TTC hasn't had to deal with. Ideally I would want someone who had that expertise.

It's more the AC versus DC than the voltage that makes it quite a bit different. It's an overnight read, but the pdf publication at http://www.ocs4rail.com/downloads/ is pretty eye opening...

Edit to add: Section 9.4 really gets into the voodoo that makes AC so different.

Regardless considering their performance on the line 1 extension I wouldnt dare chance them on such a large project

Someone asked if they could plant trees on the roof of the train shed, AMA replied with this.

This document from IO says the "GO Expansion: OnCorr" will reach financial close in 2021.

^Some new upcoming open houses related to new TPAP's on the ML website on the engage page

^ Where do you see the text about the open houses? It says the recent activity (including the page you linked to) was added 3 years 10 months ago.

^Sorry. I made a double error - a) mispointing the link and b) assuming the page that I did see matched a flyer that was going around this week.

I have only a crappy screen shot of one side of the flyer. It doesn't give dates or times, but the list of projects is interesting - and matches the page I was trying to point to. (For some reason, the UT editor forces a change in the url when I try to copy it, I'm baffled)

The thing that I noticed was the mention of the Scarborough Junction and Stouffville line Grade Separations. Hadn't seen these before.

^ Thanks. It says "starting" but is that the actual date of the open house? There's no time or location listed. There is also no contact email.

I'm excited to hear the complaints about catenary, although the tradeoff of quieter trains could shush the NIMBYs

The NIMBYs were calling for quiet electric trains all along with these various GO infrastructure projects, so it’ll be hilarious if they start to backpedal on this in any way.

Battery offers the de/acceleration and quiet and smooth ride but without the much higher initial infrastructure costs, construction disruption, and maintenance of catenary. Added to this, battery doesn't have the horrible visual pollution of catenary wires.

See our streetcar network for an idea of just how much visual pollution overhead wires cause.

I mean come on...

This line was one of the first to get electrified here, but the catenary you see in this is about 40-50 years old. A quiet suburban street in between Ascot Vale and Newmarket stations

The unfathomable visual pollution of the car parks, suburban blight, weeds catenary in Melb's outer western suburbs!

The catenary overpowers everything else in greener areas!1!

etc.

The Hor-ror, the hor-ror!!!

Is that wood - not sure what the exact term would be but let's call it a sacrificial beam?
