The most effective thing you can include in your comments is a personal story of how having two people on your crew prevented an accident from happening. It is not necessary to include all the details like train numbers or dates; just an overview of the incident and how having the second crew member made a difference. Examples of how the second crew member cleared a blocked crossing for an emergency vehicle or dealt with emergency responders during a derailment would also be very beneficial.
No one can make a stronger case for two-person crews than those who work - or have worked - on the front lines operating trains every day.
