Comments on: Dark smoke erupts from MLW M630 CP 4566, which could be due to a sudden throttle advance or engine restart. Apparently the diesel engines of the other units are running better/cleaner. In other images taken at same place same day, CP 4566 did not have visible smoke. The engines are at the east end of CP Quebec Street Yard just east of the namesake overpass, leading an eastbound train. The trailing unit has been modified by addition of numerous car body air filters; its appearance matches M636 CP 4716 in this timeframe.
