Moving anything by crane is horribly expensive. Transed doesn't have a crane in their fleet that I've seen. Any time they've had to do anything that was a large lift they had a contracted crane come in. For example unloading the rail milling machine.

Valley Line Milling Machine

Caught this being unloaded and assembled near the Valley Line OMF this afternoon. This is a milling machine the profile the track. Hopefully I can get a shot of it in action another time. - AWS_4802.jpg

Myshak paying for their naming rights on that new Metro Ballpark from just TransEd crane work alone 😂

Also, love the website. It's so up my alley looking at all the rail pics... lol

I assume they have a mobile crane they use to remove cars from the track in the event they get stuck. This could be put into service to take cars over to the maintenance yard.

That's never been a thing. They have a diesel powered powered Trackmobile for moving cars, and even then that is likely a last resort. The first choice would be use another LRV to tow a dead LRV. You don't bring out the Trackmobile until you need to move LRV's with no catenary power available. Testing was done last summer to ensure an LRV would be able to tow a disable car cup the steepest grades.
Metrolinx moved a few cars to an completed section of one of their lines under construction by truck. I believe they used a trailer and just winched the cars on and off. Pretty standard practice, no cranes needed. The same could be done here, after all, that's how the cars were moved from the freight car they were delivered on to CN's Bissell yard, to the Gerry Wright facility, and even then to the Boonie Doon and Mill Woods Town Centre when the cars were put on display.

While it is viable if the needed arises for testing, it's really not viable for day to day operations when there's already a functioning bus route.

With the amount of random stuff that keeps popping up that they are fixing it makes me have doubts the line is even capable of running. As @EdwardEdm mentioned - why is the power off to the OMF leads? Why is the power off in Millwoods? There hasn't been any work along the line in either location that I've noticed.

All of Mill Wood's (south of Whitemud) is energized again. Although the Grey Nuns Station, SB platform, has no lights inside the shelters at night. Either they've been turned off, or, something's broken. Still not energized for at Gerry Wright OMF so no trains able to come onto the mainline without being towed.

Based on this article (train vibrations), I wonder if springs could be added to the piers to buffer the vibration of the trains, something like next door to Winspear: https://www.cbc.ca/news/canada/edmonton/edmonton-city-council-transed-valley-line-lrt-1.6549116

From that article:
Korany says the vibration of trains running on the tracks will also be a factor in determining what fixes are needed.

"You have vibration, you have curved railing, certainly trains running back and forth on the line all day long for 365 days a year for how many years," Korany said.

"If you have micro cracks that we currently don't see on those other piers, compounded with the effect of vibrations from the train movement, that could be exacerbated."


How on earth is this so complex? I mean, the entire point of the piers was to support train tracks. That's why they were built. Mind boggling.
 
Maybe they can learn something from this 25+m pit they've excavated around existing Skytrain columns (and station in the background) in Burnaby.

So power is off in Millwoods again this afternoon - Western Pacific trucks parked on both tracks at MWTC, one with a big spool of cable. Signal post across the from the firehall has a pile of wires hanging out the access hole at the base of the pole with another Western Pacific truck there. Why are we still pulling wires for the signaling system almost a month after the thing was supposed to be open?

What else isn't done that they are hiding behind the pier issue - seems to be a repeat of their constant blaming the concrete in the river for delays.
 
I saw a bunch of work done on one of the piers east of 75 Street at the CN rail crossing. Also, the tarps and scaffolding are down north of Davies Station.
