In the 1960s, the Ma and Pa Railroad continued to solicit business along its line for its remaining Whiteford–York segment, almost entirely in Pennsylvania. In 1964, it added a siding long near Red Lion to serve a new cigar box factory. In 1971, the Maryland and Pennsylvania Railroad was acquired by Emons Industries. hauling slate from a quarry at Delta, and furniture from a factory in Red Lion, the Ma and Pa's Pennsylvania Division continued in operation until June 14, 1978, when the line was further reduced to the York–Red Lion section. The Red Lion freight station was closed on November 1, 1980; when the Pennsylvania town's furniture manufacturer shuttered its doors in 1984, the Red Lion section of the railroad was also abandoned.
