You know what really helps looking at other “upcoming” dense cities. Then build from their faults, like there is no difference when you do something and it turns out to be wrong… like there are are more uses cases to have a rainbow line or upgrade tracks/switches. The more people you can move the more profit for your city and business. It’s all about how quickly can you get money to move from hand to another. Make it accessible for all, as an example certain parts of north and south sides have elevated boarding, super helpful and safe for cyclists and transit users. But having it only one side really says you’re desperate to save pennies over human safety/lives.
