In the NTSB report it states that “Audio recordings of radio communication show Sanchez and his conductor, as rules require, communicated the indications of signals along the route for most of the trip.”
Further down, it also states that “As is common practice on commuter trains, the conductor was working in the commuter cars, and Sanchez would have been alone in the locomotive cab.”
How is the conductor able to effectively see and be able to call out all the signals while moving around taking tickets and stubs in the cab and other duties?
