Rail Car 101
Objective
• Upon the completion of this module, participants
will be able to describe rail transport of
hazardous materials, focusing on denatured fuel
ethanol.
General Railroad Statistics
•
•
•
•
•
Hundreds of operating railroads in the U.S.
Tens of millions of railcar shipments each year
Over a hundred thousand miles of track in U.S.
Over a million railcars in service
Over a hundred thousand employees
Railroad Statistics for Hazmat
• Over a million loads of hazardous materials are
shipped via rail
• Ethanol is over a quarter of total number of
hazmat shipments
• About three-quarters of the transportation of
ethanol is conducted via rail
• Ethanol is over one percent of all railroad
shipments

Brakes
• Hand
– Holds the car in place
– Prevents the tank car from moving and possibly
causing further damage at incident site or harm to
a responder
• Air
– If there is an incident, potential for a rapid release
of air causing the hose and fittings to strike a
responder
