A human performance study was conducted at the John A.Volpe National Transportation Systems Center (Volpe Center) using a locomotive research simulator-the Cab Technology Integration Laboratory (CTIL)-that wasacquired by the Federal Railroad Administration (FRA). The primary objective of the studywas to conducta hands-on simulator training exercise and system demonstration. A moving map experiment was chosen for the study because FRA is interested indetermining the human performance and safety implications of this technology following prior FRA research on preview information in cab displays (Einhorn, Sheridan & Multer, 2005). However, because surrogate (novice) engineers were used for the experiment instead of experienced locomotive engineers, the resultshave limited applicability. Lessons learned and general best practices for designing and running future CTIL experiments are discussedin this report. Possibilities for future research regarding operator use of moving map displays are also considered
