This rulemaking would add minimum requirements for the size of different train crew staffs depending on the type of operation.  The minimum crew staffing requirements would reflect for the safety risks posed to railroad employees, the general public, and the environment and would account for differences in costs.  This rulemaking would also establish minimum requirements for the roles and responsibilities of the second train crew member on a moving train, and promote safe and effective teamwork.  Additionally, this rulemaking would permit a railroad to submit information to FRA and seek approval if it wants to continue an existing operation with a one-person train crew or start up an operation with less than two crew members.
