For the second time in three months, with more coming, DDOT is announcing new schedules that appear to improve service on some routes without cutting anything anywhere, including 24 hour service on three more routes, three new direct or express routes [[not sure what the difference is between "direct" and "express" routes) and what DDOT calls significant headway improvements on the Michigan Avenue line.

I'm afraid there's not much detail available yet, but what there is, is here: http://detroitmi.gov/Portals/0/docs/...ce-changes.pdf
