Unlike more lanes, more trains is far easier to implement, cheaper, and basically takes up no space. The extra trains can be used to swap out during maintaince and repairs. They can also be deployed during abnormal congestion such as concerts or sports events.
If our cities will let robotaxis on their streets, i see no problem with robo trains which are literally attached to rails to guide them and would be far easier to implement emergency safety features like auxiliary brakes.
