Megan Bennett writes: “In 1827, the Baltimore and Ohio (B&O) Railroad became the first common carrier railway in the US, revolutionizing commercial travel. Its creation cemented Baltimore as the ‘birthplace of American railroading,’ says Anna Kresmer, archivist at the B&O Railroad Museum (BORM), located in the city’s historic Mount Clare Station and Roundhouse building. Kresmer analyzes and catalogs materials, supports exhibit development, and oversees BORM’s research library, home to more than 5,000 titles. Locomotives aside, BORM’s collection—including its archives, library, and small objects—measures approximately 7,200 linear feet. Most items are from the 1820s to early 1970s.”
