The Baltimore & Ohio Train Museum, previously known as the Baltimore & Ohio Transportation Museum when it first opened its doors on July 4, 1953, is a museum in Baltimore, Maryland, dedicated to displaying vintage railroad equipment. Described as “one of the most significant collections of railroad relics in the world,” it houses the largest collection of 19th-century locomotives in the United States, as well as the world’s largest collection of steam locomotives.

The museum is housed in the former Mount Clare Station and adjacent roundhouse of the Baltimore and Ohio Railroad, which is part of the B&O’s enormous Mount Clare Shops site, which was established in 1829 and is the oldest railroad manufacturing complex in the United States.

    What Our Customers Are Saying

    Live in Maryland and need new windows? Dunsmore Exteriors is the company you need to go with. We worked directly with Scott for all pricing and scheduling, then a crew came out and did the install. After it was all said and done you couldn't even tell that there had been workers in and around our house, except for our gorgeous new windows. A++++ rating for Dunsmore Exteriors!

    Scott and the crew at DE are the best! Legit the best! Scott walked us through the entire roof and even dropped off shingle samples for us to look at on a Sunday afternoon. If you need a new roof you need to use Dunsmore Exteriors!

    From start to finish Dunsmore Exteriors exceeded our expectations. Scott was on our roof the very first day and took detailed pictures showing exactly where our issues were. He helped us navigate the claim with our insurance company, and a few weeks later we ended up with a gorgeous new roof! Thank you so much Dunsmore Exteriors!!

    What can I say? Dunsmore Exteriors went above and beyond! Our roof looks great and was handled completely professionally and efficiently. We had no idea we could have a new roof this easily. My wife and I are ecstatic!

    We needed new gutters but we kept putting it off because there was always some other project that needed to be done first. Until we started noticing damage from our gutters not draining properly. Along comes Scott to our rescue! He showed us the problems, explained how they would fix it, and before our next thunderstorm our gutters were right as rain! Thanks Dunsmore Exteriors!

    Scott and Dunsmore Exteriors did an excellent job on our roof. Scott showed us shingle colors and explained the warranties that went along with each option. In the end we felt confident that we made the best choice for our home and now we have a gorgeous roof.
