Under normal circumstances, extra 40' buses out of North have been used for Waukegan School services or Ravinia. I'm not surprised some of those are still on hold.
South Holland means those are holding space.
They need new coaches, but also now's a good time to fix the operations and scheduling to accommodate (or generate) new riders.
The railcars are a step (maybe 15 years too late), but Metra still needs to get out of the 1960's with service.
