An LRV went past me while I was bicycling through Waterloo Park today. I’m not sure it was going at full speed but it was moving at a reasonable clip. Impressively quiet!

That's 507, per reports in the FB group.

I'm hoping that as they wear-in that 'the aliens are going to kill you in the pitch black darkness' shriek they made during the initial low speed powered testing will disappear forever...

Nope, that’s standard variable frequency drive nosies.... common on all modern LRV’s, roller coaster drive wheels, my Prius, and the machines I design

There is a whole subset of Japanese train fan that track the train noises based on the type of inverter. VVVF, IGBT, etc... I love it!

Lots of them, unified into a continuous shriek. Edit: Or a controller whine the likes of which I've never heard before. Haven't heard it from Toronto's Flexity Outlooks though, which is why I've been hoping it would go away once our vehicles wore-in.

I hear the motor controller noises, plus a touch of flange-to-rail contact noise through the curves (which should go away once the lubricators are activated).
You probably don't notice it on the TTC's FLEXITY Outlooks, because they're very rarely crawling along this slowly! They generally are moving through the low-speed phase very quickly as they accelerate.

LOL!!
As per the radio, 507 is holding in the OMSF and waiting to go out on the main line.
#1 SB run just started. “All timers in position! You may proceed at maximum authorized speed! Train on the move!”
That was FAST! They are at Willis Way already, having made all stops.
They are testing/timing all the crossings.

Do I understand from the timing of your messages that they got from the OMSF to Willis Way in 4 minutes? That seems almost unbelievably fast, even for an almost-straight, road-pre-empting LRT route. |
