CTA trains every five to 10 minutes all day and better Metra service at midday, nights and weekends. One app for fares and transfers across services. Buses that can bypass traffic. This is the vision for the future of transit set to be outlined Wednesday by Regional Transportation Authority Chairman Kirk Dillard at a lunch for the city’s business and political elite. Overseeing the efforts would be a stronger RTA that would coordinate fares, service and construction projects among city and suburban bus and train agencies, he said.
