St. Clair Tunnel Company

The camelback in question was originally built as a tank locomotive and was "The World's Largest Locomotive" when built.  They burned a low-gas coal briquette to lessen the smoke hazard in the tunnel.

The first camelback in the OP's first link is a very odd looking one. Thanks for sharing!

Old tunnel just before replacement, note how the standard height boxcars just barely fit.  Definately no room for Hi-cubes, autoracks or doublestacks:

Special train.  9674 was built for GO Transit, note green paint on bell:

"Excalibore" getting ready to start, with another special train of everything that won't fit through the old tunnel:

Completed tunnel as it appears today:

Additional information and photos.  I especially like the comment from the Conductor who was in charge of the special train of oversized TBM machinery:

Thanks for the link.

In 1982, I rode from Chicago to Toronto, through the original tunnel. I do not remember my interaction with the Canadian customs.

In 1997, my wife and I rode from Toronto to Chicago, in Superliner equipment, through the new tunnel. We were asked one question by the customs officer: "You two hitched?"
