In the late 1980s, the Indiana Hi-Rail operated the former Illinois Central line from Newton, Illinois to Evansville, Indiana.
This railroad had a most interesting collection of mostly Alco built diesels from several different railroads.
Included was a pair of 2400 HP RSD15s which came from Peabody Coal Company but were originally built for the Santa Fe in 1959. Because of their long low noses, railfans referred to them as “alligators”.
Also on the roster was a C420 built for the Delaware & Hudson, a 1800 HP RS11 from the Seaboard Air Line, and ex-L&N C420s #1315 and #1332 (ex-Monon #515) and S4 switcher ex-Santa Fe #1519.
“Chasing” a train on this railroad was a misnomer as one would drive ahead to the next photo location and wait and wait while the train negotiated the notoriously decrepit track inherited from the IC. Today both the IHR and this line are long gone.
