Chicago, Milwaukee, St. Paul & Pacific " For Water Service Only " tank car and The Milwaukee Road " Diesel Fuel " tank car. Both with metal sprung trucks and magnetic operating couplers.

As the C.M.St.P & P. laid tracks west, fast growing towns along the right of way were found to have inadequate water and fuel supplies. To meet the demand, The Milwaukee Road developed these cars as portable water and fuel storage facilities.

This year's fourth in a series of limited edition Milwaukee Road cars is manufactured by Lionel and will include their Centennial markings on the end of each car.
