Although sharing a common model designation, four different carbody variants existed with a total of only 59 locomotives produced.

Former Alcoa H-16-66 #721001 is privately owned, and since 12 November 2012 has been located adjacent to the Canadian Pacific Railway rail yard at Nelson, British Columbia.

It is displayed alongside CPR C-liner 4104, which has also been repainted in the tuscan and grey colour scheme.

The "Baby Train Master" and C-liner have been placed on static display beside the restored historic Nelson CPR station.

Plans are for the locomotive to be moved and displayed in time for the start of the museum's year-long 60th anniversary celebration beginning Oct. 14, 2021.
