Tesoro’s New Enhanced DOT 120 Rail Cars
Exceed New Federal Crude Oil Tank Car Standards
May 18, 2015
Tesoro is upgrading its crude oil rail car fleet with the addition of 210 enhanced tank cars that
exceed new safe transport standards issued by USDOT.
These new rail cars have many of the same safety features as the new DOT 117 standard announced
May 1 but offer additional safety features (outlined below). Manufacturer UTLX essentially modified
the design of the DOT 120 pressure car to make it compatible with existing crude oil loading and
unloading facilities.
Tesoro has consistently chosen rail cars that are among the safest and most robust available at
the time the order was placed. Ever y time we’ve added to our fleet, it’s been with cars that offer
additional safety enhancements. This latest set of cars reaffirms our commitment to continually
improve our fleet and lead the industr y in the safe transport of crude oil via rail.
