That's alot of smoke!

This is sad. To see an unpatched C&NW unit on fire. Very sad, yet so strange.

I suspect that your smoker had been holding at the signal and building some excess fuel in the exhaust manifold. Then when notching the throttle up to clear the diamonds the excess fuel burns out. In another 30 - 45 seconds that same engine could have a clear stack. Note that there is not a trailing cloud of smoke - which would indicate a continuing problem.

It's not on fire. That is an waaaay rich air to fuel ratio either with a turbo problem or excess carbon fuel in the manifold. Once that turbo spools to full boost, all that will be cleared out.

That looks like an EMD unit to me, so I'm guessing a turbo problem of some sort.

A few years ago a turbocharger let loose here in Lombard, sending pieces out through the stack. Nobody was hurt, but windows were damaged on a number of cars parked at a local "watering hole."

Saw the 8701 come throught here today, Always a great sight to see an unpatched loco some thru! Also, How on earth can you tell its a C&NW unit? Its too covered in smoke to see.

[Glen Ellyn]

When did you see 8701, and was it leading?

Oh my Carl. Ok. Once at my job I was given a truck that had a turbo problem. It turns out that the turbo blew. Allong with that the stupid driver drove the truck across the country and back, so by the time it got to me it had the following problems. Little pices from the turbine were in the following the exhause, air to air system, and air cleaner. Tons of oil was found in the air cleaner and exhaust. The customer wanted to know why he saw "blue exhaust from the stack 24/7. Oh and I found the turbine wheel all the way in the muffler, it had put holes in the flex pipe and turbo pipe. Man that truck was a nightmare!!!!!

Look at the trace I posted- headed to Global III. It's the third unit out- SD70ACe leading

[miniwyo]

Yep third unit back, SD70 leading. How do you find those traces, and how do you tell what unit is positioned where?

1st question- secret
2nd question- seen by another 'fan
