To be honest, I only paid attention to the routes and timing that affected me. I know the routes that were eliminated didn't come back, but there were some different routes were added over time. I don't know if they replaced the routes that were eliminated or if they were completely new. I do know of one completely new route in my area, but can't speak to those further out. Frequency did return. Before the pandemic most of the routes I took were back to every 10 minutes during rush hour, but spaced out more during off times. I'm not sure if that's how they were before the cuts, though. I went from taking the bus at rush hour to get to and from work before the cuts to being retired and taking the bus at different times.
