Green Line LRT | ?m | ?s | Calgary Transit

[InfrastructureEnthusiast]

When a crash like this occurs how long is service on the line sudpended for? I assume the rails would be damaged during a crash of this nature.

I guess with all the practice they've had, recoveries are fairly quick now. Service was back in a few hours.

Its not really the rails I'm worried about though, its only a matter of time before one of the collisions is bad enough to be classed a mass casualty incident..

Wildly irresponsible design that puts social engineering above safety.

If I think about the SE segment there are 5 at-grade train versus vehicle on road interactions... and those are all perpendicular interactions where they should be controlled by the arms, bells and whistles.

(1) 40th Street SE, just west of Shepard Station, there will be many more crossing on any south extensions.

Could be up to three at Douglas Glen... This alignment confuses me, are they not using the right of way? At this point I'm only counting 29th Street (2).

On the Green Line website, the line looks to go to along 114th Ave to 24th Street which would cross four parking lot entrances.

Through the entrance into the ECCO at Quary Park (3).

Shepard Road just before South Hill (4).

Highfield Boulevard SE just before Highfield (5).

I think they're going under Ogden Road just after Lynwood/Millican but maybe not and I'm not sure how it is crossing 26th Ave at that station. The station is perched up on the hill so I assume they'll be going over 26th Ave.

How often is there an accident on the Valley Line? Can the city install crossing arms? I can't imagine it's too onerous to install them after the fact.

Douglas Glen will likely be 3. There's one on 107 Ave SE, one at 29 St SE, and then there's the bus only access that connects 27 St and 114 Ave which will be reconfigured as part of the bus loop changes but I think will remain open?

Ogden road is an overhead crossing though not under.

The Ctrain even has crossing arms for people. Not sure why they can't on the Valley line.

We managed to keep one of the busiest rapid transit lines for a city under 2 million in the Western Hemisphere running at full capacity while completely rebuilding a station for like 80% of the construction period.

With the Valley Line’s extremely low ridership, it shouldn’t be a problem installing crossing arms. Would only be a positive addition.

It's too bad. I really wish they'd build an overpass for the LRT crossing at Highfield Blvd. There's already one there for freight:

So, the green line website is wrong on the high-level station layout?

I really wish they'd build an overpass for the LRT crossing at Highfield Blvd.

In the 60% station design you can see the crossing arms depicted. So, it will unfortunately be at grade.

I'm sure they could, and they likely will. But you know what they say about trying to make something idiot proof...

I'd really like to see a cost estimate on how much it would take to make the SE route fully separated.

No other changes, keep the trains and stations the same, just how much getting rid of those 5 crossings would add to the project.

The current 5 crossings wouldn't be too hard to deal with...it's all the future crossings as you move further south that would probably require going fully elevated the whole way. I think it still might have been worth it though

I never noticed the conflicts with some spur lines here - it looks like at least one of them is still in service (near the top centre of this photo you can see 4 train cars on the east side of the building that's just south of the bunch of school buses parked - it's called Hood Plastics on google maps). Does it stay elevated from Blackfoot Tr until just before Highfield Station?
