The last four steam engines the McCloud River Railroad purchased in 1925 were oil-fired and made by ALCO. The numbers 20 and 21 from 1924 already had the wheel arrangement 2-6-2 and came from Baldwin. Then numbers 22 and 23 with the same wheel arrangement came from ALCO. The numbers 24 and 25, which were again delivered in the same year, had two inches larger coupling wheels and larger cylinders to compensate.
They were in service with logging operations until the mid-1950s, when steam operations ended at the McCloud. The number 25 was reactivated in 1962 for special trips. After operating on its original route with some interruptions until 2001, it joined the Oregon Coast Scenic Railroad in 2011 and is still in service today.
