My Aunt mentioned this today during our visit, and it looks like a blast:

The Western Maryland Scenic Railroad round trip excursion is an exciting mix of mountain scenery and rich transportation history. It’s an entertaining and educational experience riders of all ages and interests with interpretive history and lively Main Street Districts at both ends of the trip!

The three and a half hour round trip includes 90 minutes in historic Frost burg and for $48 bucks you get a meal too. There is no menu page, it looks like menu might change, so I picked a day at random and this is what they're serving:

The following menu is available on the Western Maryland Scenic Railroad. If you purchase train tickets that include a meal, you will be asked to select your preference of one of the meals below:

• Roast Beef and Gravy on Texas Toast served with Mashed Potatoes and Summer Blend Vegetables.
• Turkey Club with Chips served with sides of Carrot and Celery Sticks and Macaroni Salad.
• Macaroni and Cheese served with a cup of fruit.
• Vegetable Lasagna served with a Salad
• Hot Dog on a bun served with chips and a cup of fruit.
• Peanut Butter & Jelly Sandwich served with applesauce and a cup of fruit.

Not exactly gourmet, but most likely tasty. After returning to Cumberland at 3pm, there is certainly a ton of history to see, and a good number of attractions and a few places to eat.

Now I just have to set a date, and get my tickets!
