This is Brandt, a conductor on the Great Smoky Mountain Railroad. Brandt has been with the railroad for over 24 years - he spent four years working in the repair yard before moving over to the shops and taking a role on the train.
If you take a look at the movie the Fugitive, you’ll see Brandt in the background after the crash scene. The Great Smoky Mountain Railroad was responsible for staging the scene; they crashed three different types of train to get the rollover action they were in looking for. (Brandt says Harrison Ford was delightful).
