I often hear people say things like, “Light rail might make sense in Europe, but it doesn’t make sense here because our city isn’t dense enough.” To which I respond, “Light rail doesn’t make sense in Europe either.”
In fact, based on the numbers in the post on moderate-capacity transit, we can derive the following Antiplanner’s Law of Rail Transit:
By the time a city is dense enough to justify rail transit, it is too dense for light-rail transit.
