A business trip to Sarnia, ONT provided some post-work railfanning.
At the time of my visit, CN had a tunnel under the St. Clair River,
which connected Sarnia, ONT with Port Huron, MI. However, the
tunnel was old and could not accommodate the high (exceeding Plate C)
freight cars, so a car ferry was used for the high cars. The car
ferry operation was quite busy and ran pretty much non-stop the entire
time of my visit. They were just starting construction on a new
larger tunnel next to the existing bore, so I included some piks of the
stopped and took some pictures of the EMD London, ONT locomotive plant
and few shots are included of it as well.
