Last week we worked on a 47 car derailment in the St.Clair Tunnel between Sarnia Ont & Port Huron Michigan. It was one of the toughest jobs in years. Many heavy cars and a 200 ton DPU locomotive had to be dragged through the ballast stone and clear of the 6,000 foot tunnel.

I have no idea. After a few dozen wrecks you don't care, just there to clear them up. The last thing it would be in that tunnel is poor rail... Its heavy rail, concrete ties in new condition and very well maintained. Could have been any number of things.

Just like a wrecker outfit, but instead of cars and trucks, its trains. The railroads call, we go.

You have to assume that when a derailment occurs outside that the energy is dissipated by the cars going every which way. My impression is inside the tunnel, they expend that energy by smashing each other into wreckage? Looks like a lot of twisted iron to dig/yank out of there?

Which end did you go in through, Canadian or US?
I'm not afraid of hard work; I can lay down beside it anytime and take a nap.

We worked from the Sarnia side, and Yep with no place to go, some of those cars were mangled beyond recognition. It took 9 big cats and a track derrick to pull the locomotive out, we dragged it nearly 3,000 feet in balla. It had minimal damage and at four million bucks, they sure did not want to cut it up in the tunnel. One of the biggest wrecks for all around difficulty and size I have ever worked. It was a pure brute force job. We used cable as big as 3" and 150 ton shackles to get heavy enough rigging to hold together.Everything had to come out by straight pulling power.

Hi, Tim T.
Thanks for all the shared material. Great stuff.

I have worked in railway tunnels several times in the past. With heaps of diesel engines in there, often under full load, ventilation is quite the issue and being around 3,000 feet in would make it all the more so, especially with multiple trips and even more so for the people staying in there between pulls. Would it be a 'rude' question to ask how they coped with that?

Just my 0.02.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
