Chesapeake and Ohio No. 490 is the sole survivor of the L-1 class 4-6-4 "Hudson" type steam locomotives. It was built by Alco's Richmond works in 1926 as an F-19 class 4-6-2 "Pacific" type to be used to pull the Chesapeake and Ohio's secondary passenger trains. It was eventually rebuilt in 1947 to become a streamlined 4-6-4 for the C&O's Chessie streamliner. After the Chessie was cancelled, No. 490 remained in secondary passenger service, until it was retired in 1953. It spent several years in storage in Huntington, West Virginia, until 1968, when it was donated to the B&O Railroad Museum in Baltimore, Maryland. It remains on static display at the museum, as of 2022.
