This car was built for the Union Pacific in 1962 by the St. Louis Car Company, and delivered as baggage car 6334.  As passenger service wound down, the car was converted in 1973 to a tool car for use in snow plow service for the railroad.  The car was renumbered at that time to 904304.  In 1981, the car was assigned to the Heritage Fleet and dedicated to the Steam Program based in Cheyenne, WY.

The car was named the Art Lockman in 1992 after the long time Union Pacific employee of 43 years.  In 2003, the car returned to its original number of 6334.

The Art Lockman has been upgraded continually over the years to better serve the crew and locomotives while on the road.  The most recent updates were made between the end of the 2019 trips and 2021.  Most noticable changes were the removal of underside storage tanks and the addition of 3 large storage cabinets and a Microphor tank.  Today the car has storage for grease, oil, and solvents in addition to a generator, tools and work space to support most operations while on the road with the steam locomotives.


Our HO scale model is still in development, but the photo above shows the completed bottom, trucks, sides dors and other parts.  The photo of the 44 parts that make up the bottom is below.  As with our previous Lynn Nystrom car, the side doors will slide to any position, and the roof is held in position with magnets.  When released, the car will have an optional full length interior, something not even available with brass cars previously produced.

Best estimate is late summer 2023 when this car will be ready for sale.  Pricing has not been determined yet, but will be a little more than the Lynn Nystrom.  Deposits will be accepted for a limited number of fully assembled cars hopefully by the end of March.  If you are interested in this car and are not already on our waiting list, please send an email to info@railfanmodels.com.

We will add more photos as the car gets closer to production.  The model has many user friendly features and accurately depicts the prototype car.  Many of these include:

  • All four side doors can slide to any position
  • The roof is held in place by magnets, so it can easily be removed and then snaps back into place
  • Stainless Steel grab irons
  • Etched metal coupler cut levers
  • Head-end power connectors
  • Complete underside details with all electrical cables, conduits, and air lines
  • Correct cross-section of center sill
  • All cross members have pass-through cut-outs per the prototype car – something no other models have except ours!
  • Trucks with the correct wheelbase, entire frame, and separate span bolster
  • Metal wheelsets with vented brake rotors on the end axles
  • Complete brake beams with calipers on end axles
