    • FMC 5077 50ft Box Cars
      This is FMC’s entry into the Plate B IPD (Incentive Per Diem) box car era. The design was intended to be the “most universal”, interchangeable on most common railroad clearances. The cars were available with and without end-of-car cushioning and offered several door configurations. Over 4,300 cars were produced from 1975-1979 by FMC’s Portland, Oregon plant. The cars were delivered in numerous colourful shortline paint schemes and the nationwide carpool fleet of Railbox. Many secondhand cars were later seen in Class 1 railroads and large leasing company fleets under additional shortline reporting marks.
    • FMC 5327
    • FMC 5347 50ft Box Cars (Athearn) Trovestar
      It was the mid-1970s, and the incentive per diem box car boom was beginning. New, brightly painted box cars seemed to appear overnight. Many were lettered for various short lines. FMC (Food Machinery Corporation) built many of these cars. The 50’ outside post, non-terminating end box car, became the foundation for new per diem cars built in the 1970s. The 50’ FMC cars also varied in door configuration and style to suit each customer.
    • 56′ Thrall All-Door Boxcar
    • 53′ Evans
      This 53′ boxcar was manufactured in the 1960s and ’70s by Evans Company and was used primarily to haul produce, wood and paper products, and canned goods. This railcar is an insulated RBL (Railcar, Passenger Service, Insulated) featuring a 16-foot opening and double plug doors.
    • NSC 50′ Plug Door Box Car
      Steel boxcars became the de facto standard for railcar service sometime in the late 1950s. Every major railcar manufacturer had their own version. Plug-door cars held a better seal for air coming in and out of the car interior and operated much the same way a modern minivan side door works. A common feature for plug-door cars such as the offering from NSC was an insulated interior to further protect the contents from the elements. From 1975 to 1980 National Steel Car built over one-thousand 50’6” single-plug door box cars. This being the post-roof walk era, these cars have a simple aluminium roof. Model 5277 had an interior capacity of 5,277 c.f. and model 5177 had a capacity of 5,177 c.f. Most of the 100-ton cars went to Canadian railroads primarily for paper service. Two hundred 70-ton cars went into food service for the Grand Trunk Western.
