Oh come visit Annapolis, yes it is a flyer but great time of year and FWIW, Star Hobby is 2 minutes west of the Bay Bridge
Regarding 1:1 trains, the Maryland and Delaware RR runs occasional trains on their three sections of track, not very often, but perhaps a trip to one of their yards or parking areas to see really vintage locomotives (RS-3) would be worth it

And NS runs it “famous” rock train down the Delmarva on a regular schedule, there was an article on it a few years (?) ago in Trains mag
Have a good time
