I'm not an engineer, but the drawing of the crossing at Erb/Caroline looks different.

could someone post this drawing again? or point to it?

Huron spur is now connected to the track over the bridge rather than the detour.

   

That is the track aligning machine on the curve.

The functional design plans are here: http://rapidtransit.regionofwaterloo.ca/en/projectinformation/functionaldesignplans.asp

Here is a drawing of the intersection

The solid black lines might(?) be "PROPOSED FLAT CURB FOR LRT GUIDWAY (sic)" in this Schedule 15-2 Appendix G: http://rapidtransit.regionofwaterloo.ca/en/projectinformation/resources/AppendixGGen.ConditionDraw.RFPV3Set.pdf

Track through Erb/Caroline (shared line) currently placed is ballasted + deck plates. What do you want clarification on?

RE: King Street Underpass at the Transit HUB - KevinL - 08-23-2016

If i can address what I think is timc's concern - the trackage through the intersection will be of two types. The straight track (LRT northbound, freight, upper in image) will be ballasted with concrete plates. The curved track (LRT southbound, lower in image) will be embedded.

RE: King Street Underpass at the Transit HUB - timc - 08-23-2016

I guess I just don't understand how to read drawings. I avoid the uptown area for the most part, so I didn't know it was already done. Thanks!

RE: King Street Underpass at the Transit HUB - Canard - 08-23-2016

I don't think the drawings specifically differentiate between embedded and ballasted track. But we know this will be the case (Kevin's post above) based on observations.

All trains are now moving over the new King Street grade separation. I just watched a VIA train go over. Now they can remove the bypass track, dig it out and reopen King Street when they are done. The bypass track has been disconnected. The freight in the picture above, only had access to the Park Street spur before.

That freight train goes past my house, I watched him reverse direction several times before finally continuing on.  I wonder if that was related.

Exciting times.  I do hope this means the Via trains will be able to keep a bit more speed on, given right now, they lose a lot of time through Kitchener.

What time was that?  Afternoon?

RE: King Street Underpass at the Transit HUB - danbrotherston - 09-04-2016

Yes. Probably around 2 PM.

Ahhh ... we were sitting in a car on Victoria waiting to cross the tracks about that time.  It took a while for the crossing to open!

Heh, yeah, there were a lot of cars backed up by the time they did.  

Worth noting, and I doubt many people know this, if a railway crossing has no arms, it is effectively a stop sign.  If there is no train imminently coming, it is legal to proceed after stopping.  Of course, given that people seem to be a poor judge of how fast a train might be moving, perhaps it is just as well that people believe they must wait.
