I'll go out on a limb here and suggest that retrofitting our LFLRVs with autonomous tech might not be too difficult once the autonomous technology is available on the market. As long as the LRVs are fly-by-wire, it should be pretty straightforward to connect an autonomous driving system to the controls of the LRV.

The more difficult parts might actually the upgrades that would be needed elsewhere in the network. For example, all the network switches would need to be electronic, as they'll be no drivers available to manually move the switch. This won't be an issue on the Crosstown, but it will be an issue on the legacy streetcar network.

Electronic communications between Transit Control and the LRVs would need to be improved as well, as failed communications system would be catastrophic under autonomous operations. I'd image that some combination of cellular networks (4G, 5G, etc...) and mesh networking (essentially the streetcars wirelessly relaying messages between each other) would be sufficiently reliable. These solutions are proposed for use in autonomous automobiles as well.

It's exciting to think about the service improvements that would be delivered by autonomy. Operating costs would be significantly lower, which means we can afford to run additional trams. And without having to manage people, you'd no longer have to deal with layovers to switch drivers.
It occurs to me that the 407 Transitway would be a very good environment for demonstrating low floor automation (among other things I rather strongly suspect that whatever the GTAA comes up with will be a single mixed busway/LRT corridor between Humber College and Renforth).

Why? The 407 Transitway is planned to be fully grade separated, there is absolutely no advantage to using low floor tech for any rail conversion for that corridor. How about we don't pull the same mistake as Ottawa and make a fully grade separated low floor line.

The 407 transitway is a 2050 or later project. A lot about transportation tech will change between now and then.

I wonder how many of the east end Traction Power Substations are complete and ready to operate. From past ML notices
TPSS 9 - Don Valley
TPSS 10- Victoria Park
TPSS 11 - Warden
TPSS 12 - Birchmount

I am sure there is redundancy and interconnectivity so maybe only one is needed to begin testing

- Paul
Just curious: At which underground stations are TPSSs 1-8 located?

So with the instillation of overhead wires from Brentcliff to Kennedy and potential train testing by the end of the month, my 2 questions are:
1. How are they going to get the test train over there? As for as I know they've only brought trains a few stations away from Mount Dennis.
2. If they instead transport a train to the east end just for testing, where will they keep it? Maybe at Kennedy or Science Centre so its inside?

Kennedy is nowhere near complete enough to "safely" store a train inside. Yes it is a cavern but I don't think it is powered yet nor do I think Metrolinx wants vehicles parked in a construction site for any length of time
