With Reading Railroad T1 No. 2101, the Chessie System ran several excursions during the late 1970s. From the GSVP show "The 2101 Story" https://rfd.video/2101Story | Steam Giants

1980 was the year we saw the revival of former C&O 4-8-4 number 614 as she returned to steam and powered the Chessie Safety Express excursions. The revival of the 614 was because Reading 2101 was damaged in a roundhouse fire in 1979. From the GSVP show "C&O 614 Revival" https://rfd.video/614Revival | Steam Giants

Reading Railroad 4-8-4 T-1 #2101 is fairly fresh from running the "American Freedom Train" in the east and now performs on the "Chessie Steam Special", celebrating 150 years of the Baltimore & Ohio Railroad. From the GSVP show "The 2101 Story" https://rfd.video/2101Story | Steam Giants
