GO Transit: Construction Projects (Metrolinx, various)

My uneducated guess for the 4 stub tracks TK10E, TK10W, TK13E, and TK13W is for VIA departures; and potentially other express train departures depending on the platform length. VIA arrivals can unload relatively quickly and then pull forward and back into the stub tracks as they prep and wait for loading as departures.

Thanks. Will update it and repost later.

Metrolinx hasn't mentioned it but they have gone to significant effort to ensure it is an option for bidding based on discussion with short-listed bidders. Commuter rail electric locomotives are quite cheap and most existing GO rolling stock is usable for several more decades.

Seems like false economy to spend billions on electrification and hobble the system with slow-accelerating locos. I'm sure GO's existing cars could be used elsewhere in the network or even sold on as there are other operators in North America that use very similar cars.

For example we could sell some to Alberta's potential Calgary-Baniff service.

Well according to the IBC, Electric Locos if bought will be used for extra rush hour trips on electrified corridors (This is from 2019)

While the plans could've easily changed since then, I feel like this is the most sensible option for rolling stock reuse. Make most of your investments into EMUs, and then get a couple Electric Locomotives for additional trains you need during rush hour, and use them in conjunction with the older bilevel coaches.

The tender included (or did before it got broken up) minimum performance characteristics. If it's a custom build, and given the lack of North American EMUs for most vendors it probably will be, they'll not go much beyond the contract requirements.

The fastest trains in the world are electric. They don't have to carry the extra weight of fuel, that would slow them down.

His point is about electric locomotives vs electric multiple units (EMUs). An electric locomotive is limited by the fact it doesn't distribute the power across wheels throughout the whole train, so while it will accelerate faster than a diesel locomotive its performance and energy efficiency doesn't compare well against an EMU.

Metrolinx is expecting Electric Locomotives (hauling existing GO cars) to be the preference of the winning bidder (6-car 1EL, and 12-car 2EL), rather than EMU.

Or, at least they're not ruling it out when planning yards, platforms, noise profiles, etc.

What are you basing this on? Like you said, you need to design for the worst-case design vehicle, which in terms of weight, length and noise would be a locomotive-hauled train. That doesn't mean they necessarily expect locomotives to be used on the short-distance local services. Electric locos make sense for the longer-distance express services such as to Barrie or Oshawa.

On this note, while I've been commuting recently I have been tracking the speeds of trains with my phone, and I noticed that although the EMU bilevels (NS VIRM) are faster from 0 to 100 km/h, the electric locomotive-hauled single-levels (2x Bombardier Traxx + 9x coaches) are actually faster from 100 to 140, probably due to their higher power output (10800 hp vs 6404 hp)

Just a quick construction update at Milliken GO. Formings are progressing for the north side of the underpass, aswell pavers are going in between the bike path and the sidewalk. There was much larger pavers on site aswell, I assume for the bike path but it could be for something else.

Why do they need to be high floor? Also how many stations does VIA currently serve that are high floor?

VIA serves 3 high floor stations currently. High floor means easier and faster boarding for all, and as someone who cares about the elderly and differently-abled this is important for me!
