| The durable 4-4-0 had nation-wide appeal through most of the 19th-century, earning it the name “American.” The Pennsylvania Railroad perfected its design, creating the D16 class as the most modern American-style locomotives ever built. No. 1223 pulled passenger trains on Maryland, Delaware, and New Jersey lines for 45 years. The locomotive was retired in 1950 and later borrowed by the Strasburg Rail Road beginning in 1960. It would once again return to steam service in 1965. It also pulled daily tourist trains and special excursions on the Strasburg Rail Road from 1965 until 1989. |
