Caption: CN 433-21 is a brand new Plasser MPMV (Multi-Purpose Maintenance Vehicle), or Crew Crane Transporter (CCT), and is being mainline tested near Charny, Quebec back in December 1988. This machine concept was introduced when CN accelerated the downsizing/consolidation of section forces and utilized multi-function machines to offset the reduction in manpower. One phase of the project was known as TFM (Track Force Mechanization) and involved the development of manned camps at several remote locations in northern Ontario in the pilot project.
