CAT does not serve Hanover, rabbittransit does. You'd have to take rabbittransit route 16 or 20N or 22N to York and then transfer to either rabbittransit route 83S or Greyhound to get to Baltimore, then take the Baltimore Light Rail to BWI. It's about a 4 hour ride.
I dont know, yet you can refer to the Cat website and you can be further helped there. Thanks for asking.
