Career Fini

Most recent 244 prime mover: The second CPR 4016 FA-1 was created in 1966 from components re-cycled from RS-10 8557 and FA-1 4014. [info per Patrick C. Doran's CPR book]. 4016 – 2 retired by the mid 1970's.

Preservation: Research to date shows that not one CPR FA-1, FB-1, RS-10, RS-18 are preserved . Ex CPR 4090 in Cranbrook is a FA-2 with FB-2 #4469; and stateside four RS-18u (the chopped nosed kind) are (were?) in service at operating museums. And VIA's sole RS-10s 8558 lasted only a few years, retired 1981. As of December 2025, are all OSR's MLW's sidelined? And GIO#1859 in service?
