Depending on your definition, this actually is not peak performance.
Subways are.
Obviously, the tunnels are absurdly expensive, but nothing moves as many people as quickly around a city as a subway.
They're also extremely reliable, meaning people are even more likely to actually use them, and their above-ground footprint is essentially zero.
Agreed, trams look good, but they aren't able to move as many people as a train because of the limitation of the positioning of the doors. This means that for the same traffic you need more carts, and bigger, more expensive stations.
In cities where the density isn't that high, digging a subway isn't ideal, and you'd probably be better off with a tram, but for high density cities, subways are peak.
Generally speaking, the digging has to be done once, so I think it's a good investment for a lot of cities.
Trams are, as you've noticed, a different usecase - subways are for getting you from A to B quickly, and trams are for getting you to the subway stop/straight to your destination on a shorter trip. One prioritises speed and throughput, the other - access and ease of use. Both should be used together to form a good transportation network, with buses and trains going to more remote/less dense areas.
Agreed 100%.
This is all a very abstract discussion. In Munich we have all - light suburban rail, a subway, a tram system and a bus system.
It's not either or, but a very specific discussion which system is best for a specific use case given the existing city where you put things in.
We have parts where the trams sharing space with buses or even cars, that's where the tram network is just kind of a higher capacity bus.
Other parts has dedicated spaces for the tram rails, they are connected to traffic signs so trams are nearly as fast as the subway.
Currently the city seems to build more trams as the subway network is at a capacity limit - and they can't increase it without huge investments.
There's a new subway line planned, as well as construction for a second light rail tunnel crossing the city underway - but those are hugely expensive, long term projects.
Sometimes they build a tram first, because it's a lot cheaper to plan and implement and then replace it by aubway 15 years later.
And yes whe also have a tram line which uses a corridor of a former train line, so it looks like the picture. Whenever I go there I love that place, trams and buses available but no through traffic by cars (You can still go there by cars, but no through traffic as the whole area is a cul de sac)
