After more than half a century of technological development some solution for this problem is certainly viable.
But it's important to analyze how necessary regular trains are nowadays, when they are necessary, the costs, the demand, what are the political pressures... because there are many other good solutions for city mobility being completely ignored.
Smart traffic light control to prevent traffic congestion, a service similar to Uber Pool using minivans and other small vehicles to replace shitty buses, over-the-street fast buses, gyroscopic single rail trains, smaller modern aicraft... are some possible solutions.
