A demonstration run of the <i>Chesapeake</i> makes a station stop at Perryville on April 30, 1978, the day before it began regular service. This run used Arrow II railcars being ferried to Washington for Washington-Baltimore commuter service; both Arrow II and Arrow III cars were used for regular service.
