I don't understand why people obsess over transit form, at all. The point of transit is functional; 95% of the point of transit is if it can get people places conveniently; how it looks or how much it makes you feel like a big boy when you ride it is worth 5% or less.
I think Edmonton wishes they had our transit: they're currently building a line at-grade through their downtown, and they have all the knowledge of the system they have. Something that I don't think is appreciated enough (and the current lower frequency doesn't help) is that our 7th Ave LRT provides a real benefit in having a frequent, fast and free way to go from one end of the downtown to another. Adding in a couple of flights of stairs on either end would handicap that substantially.
Their system is half the size of ours because they spent a ton of money on the underground portion, couldn't afford the suburban extensions that drive ridership, and were politically handcuffed with the initial system finishing in a tunnel. If you think their system is better than ours, please specify which two legs of LRT you wished we didn't have in exchange for the downtown tunnel.
There are definitely some benefits to having the train at grade. Last time I was in Ottawa I rode the LRT and was able to compare the 'look and feel' to ours. for the most part both systems kind of feel the same, except for downtown of course, where Ottawa's system has three underground stations.
Ottawa pros
-Train doesn't need to stop at lights when going through downtown.
-Stations are warmer in the winter.
Calgary Pros
- I love that you can just walk up to a platform in DT Calgary and hop on, do a couple of stations and hop off, and for me this is a huge pro. You don't need to spend a half hour going up and down multiple flights of stairs and escalators just to get to/from the platforms. Frankly it's quite a pain in the butt.
-You can see the trains coming from quite a distance. I know you can look at signs or use an app, but seeing a train visually coming from a distance is nice.
-Open fresh air above ground in the summer/spring/fall. One thing I've never enjoyed is heading down to the stale air of an underground station on a nice day.
-I like being able to look out the window and see things while travelling on the train.
If Calgary's trains didn't have to stop at traffic lights downtown, I would never advocate for an underground tunnel. It might seem cool off the top, but it's a real inconvenience. Having it at surface is so much quicker and easier for people to use it.
Also as a side note. I don't want to make it seem like I'm picking on Ottawa's system. I've used a good 40-50 LRT/Subway systems around the world with underground stations, but for comparison purposes it's best to use Ottawa or Edmonton, and I haven't used Edmonton's in about 20 years.
