Paradise was the site of a former station on the Catonsville Short Line railroad, one of several stations that included the main depot in Catonsville and stops at Bloomsbury, Kenwood, St. Charles seminary, and the terminus at St. Agnes. The Catonsville Short Line Rail Road Company was officially incorporated on February 25, 1882, and operations began on November 10, 1884. The railroad ran about 3.6 miles from St. Agnes Station, on the Baltimore and Potomac Railroad, to Catonsville, passing near Loudon Park Cemetery, through the property of Dr. Liebig and the Tinsley's Paradise estate, continuing west through the Spring Grove Asylum, under Bloomsbury Lane, and reaching Frederick Road near its junction with Mellor Avenue. It hauled lumber for new home construction, and large quantities of coal were delivered to St. Charles College and Spring Grove State Hospital. In 1897, the new Catonsville trolley line drew away much of the railroad's passenger traffic, leading to the discontinuation of passenger service in 1898, though the BBP continued freight service on a flexible schedule. The Short Line was sold to the newly formed Caton and Loudon Railway in October 1945. After the last load of coal was delivered to Spring Grove State Hospital in December 1970, trips over the Caton and Loudon became very sporadic, and the last carload to Catonsville came in April 1972. In June 1972, Hurricane Agnes destroyed much of the track, leaving the railroad unsalvageable, after which it fell into disrepair and became overgrown. Present-day Paradise Ave was originally called Spring Grove Avenue because it led to one of the three entrances to Spring Grove hospital, which became known as the Paradise entrance, and the Paradise Gatehouse still stands today.
