In 1889, business partners Gustav T. Hetschel and Henry Frost established a general store and post office near the Annapolis and Baltimore Short Line Railroad. The new rail service connected Maryland's economic and political centers and encouraged real estate speculation along its route. Frost served as postmaster and ran the store, while he and Hetschel also laid out the residential enclave of Erleigh Heights on the Severn a little over a mile away, where Jumpers Hole Road meets the Severn River, now Carrollton Manor. Baltimoreans bought summer-home lots there and reached the community by way of Frost's store, which stocked needed supplies and also served informally as a rail station and ticket office. The stop was one of thirty between Camden Station in Baltimore and Bladen Street in Annapolis, and its name changed to Earleigh Heights in 1892. Combined post offices and general stores were common along railroads in emerging towns, but only a few survive in Anne Arundel County. This building, a rare and highly intact example of Second Empire style in the county, has a two-story tower, a decoratively shingled mansard roof on the main building and tower, arched dormer windows, and economical German-style wood siding typical of the late 1880s. A store operated here until 1943, when the building became a residence. Anne Arundel County acquired it in 1988 for use as a ranger station for the Baltimore and Annapolis Trail, the thirteen-mile paved hiker-biker trail that follows the railroad route, and a full restoration was completed in 2020 so it could continue serving as a ranger station and railroad museum. The railroad itself opened direct passenger service between Annapolis and Baltimore on May 9, 1897, transformed development along its route, supported freight service for farmers, shifted from steam to electricity in 1908 as the Maryland Electric Railways Company, merged in 1921 into the Washington, Baltimore, and Annapolis Railway as the WB&A's North Short Line, reemerged after the WB&A bankruptcy in 1935 as the Baltimore and Annapolis Railroad, ended passenger service in 1950, and saw its last B&A freight train in May 1992.
