Amtrak No. 231 is an EMD F40PHR built in 1977.
History[]
The locomotive ran passenger service throughout the western United States until its retirement in 2001. The locomotive was a regular unit pulling Amtrak's Desert Winds trains between Los Angeles, Las Vegas, and Salt Lake City.
Upon retirement, it was sold to DLMX and repainted in a Daylight paint scheme. Dynamic Rail Preservation later acquired the locomotive along with Amtrak No. 644 and by 2024, the locomotive was fully restored to its original Amtrak livery. Currently, it needs new traction motors due to vandalism damage while stored in Oregon. In July 2025, both the 231 and 644 were donated to the Illinois Railway Museum, and arrived there later that month.
On August 15, 2025, 231 moved under its own power for the first time since 2002 thanks to its traction motors being restored.
