A brand new Track Evaluation Train at the Canadian Pacific Railway’s Toronto (Agincourt) Yard on April 18th. The three cars behind the locomotive are an accommodations car (CP94), the generator car (CP93), and the Track Evaluation Car (CP92) (TEC) which gives the train its name, the TEC Train. The third car has a big rear window for observing the track, and all kinds of laser measurement and evaluation equipment. The goal, is to find track problems before they become problems so crews can be sent out to fix them. The constant laser measuring of the railway performed by these trains means there are reference points in time to compare the track, looking for shifts that might signal a problem brewing.
