Southern Pacific Railroad (SP) 2355 is one of 10 heavy 4-6-0 'Ten Wheel' steam locomotives built by Baldwin Locomotive Works in 1912, designated the T-31 class. 2355 was retired from service in 1957 and was converted to a static display at Pioneer Park in Mesa, Arizona.[5]
The locomotive was fenced off for safety concerns in the 1990s.[6] Since 2008, efforts have been underway to relocate 2355 within Pioneer Park and perform cosmetic restoration.[7] Restoring the locomotive to a running state from its current condition is deemed to be cost-prohibitive.
Southern Pacific 2355 still sits where it was left in Pioneer Park. It was not relocated. The locomotive and tender have undergone a complete cosmetic restoration. Asbestos material and lead-based paint have been removed. Its paint was stripped completely using an environmentally-friendly blasting material. Polyurethane paint was applied and the train's electronics have been updated. Informational, interactive signage has been installed along with a completely new lighting arrangement. Cab control restorations continue. There also plans to mount plaques listing all the donors and persons helping with the train's restoration.
