To our supporters: Dynamic Rail Preservation Inc. has relocated locomotives 231 and 6976 to the Nevada State Railroad Museum in Boulder City, NV! After eight years of being in storage, they are getting much needed work done.


The work on addressing leaks in the engine's cooling system is now complete, thanks to the generosity of Matt Monson (of Dieselmotive Co.) who loaned tools and donated supplies. New fuel and oil filters were installed, and the next step toward operation is to acquire locomotive unitized starting batteries. This is where we need your help!

We need to raise $6801 for a set of unitized batteries (delivery included!). Once the locomotive is fired up, it will run some test trips, and by that time, we'll resample the lube oil to determine whether we'll need to change out the oil. You can contribute to a new set of batteries by donating at the link below:

July 6, 2019 - Cab floor rejuvenation

As is to be expected with any rust project, restoring the battery boxes has now devolved into taking the heaters, cab flooring and other components apart. This will address corrosion, clean-up, welding new steel, and installation of new piping and flooring.

DYRX 644 was renumbered to DYRX 6976, to honor its heritage as a Maersk-Sealand promotional locomotive.

March 14, 2019 - Electrical checkup

While DYRX 644 still needs starting batteries, we were able to check up on its electrical system using aircraft-grade batteries capable of supplying 64V. The headlight, in-cab instruments including speedometer and alerter, and the gyralight are all functional!

Temporary 64V supply; unitized batteries it had last time we fired it up was transferred to
other rail equipment by previous owner before the locomotive went into storage.

January 6, 2019 - Moving from Ogden to Boulder City

At the first of the year, the locomotives relocated from Ogden, Utah to Boulder City, Nevada. Union Pacific towed them on a manifest train to Arden Yard in Las Vegas, where a local train spotted them up by Railroad Pass for the museum to pick up. DynaRail board members donated toward the costs of preparation work, including fuel removal, shipment on Union Pacific Railroad, and associated related costs.

Both locomotives were required to be drained before movement.
Thousands of gallons removed; costs donated by DynaRail board members.

Wheeler CAT was a big help in accommodating portable air for brake inspection.
