@jeremiak The Q-Line, an inter-city light rail line, was recently launched. That helps connect the Downtown #Detroit area to the northern areas of Midtown and New Center.
That is a free service and I take that often.
We also have an elevated, "People Mover" automated train that loops around the core downtown area. Unfortunately, though, the People Mover fare system is perplexingly not integrated into the other Detroit-based transit options - relying on coins and tokens.
