I think I can I think I can (AKA Locomotive thread)

^Good to know, thank you! We might be doing a road trip up that way so that would be a great stop.

My oldest son (five) is a train fanatic. Does anyone have any suggestions as far as being able to show him around one? Should I just call up a yard? Is that a thing?

We've been to TravelTown to see all the "steamers" and will be going to the "Polar Express" deal at the Grand Canyon in a couple months.

I dont know what travel town is, but there is an.....●●●AWESOME!!!!!●●●...train museum in sacramento. Ive been there 3 or 4 times. It never gets old to me.

I thought this was kinda cool. I'd love to work on a Steam locomotive.

^ c27?

CAT 3512. Oldie but a goodie.

It was rebuilt at some point in the 80's and one of the guys working on it left a pipe wrench in the oil pan on accident. I'm sure you can put two and two together once they started going through some rough seas lol..

I recall that, at least on small marine diesels, there's a steel plate that will close off the intake. Not sure if that works on 10,000hp

I've seen something like that on some of the older Caterpillar 6 cylinder motors on a few crab boats, they use em for hydraulic pumps and electricity..

However all the mains I've seen on crab boats don't have them for some reason. The boat I'm on has a massive V12 with two turbochargers. The air filters are literally mounted to the compressor housing on the turbo. When they are spooled up you can feel the suction even a few feet away from the filters. My god it sounds great though.

[Exodus_2pt0]

There is an electric pump that feeds oil to the turbo, auto runs for 20 minutes after shutdown.

I'm not positive if it is fed also by the mechanical oil pump or not. Although the turbo also had a gear driven setup with a centrifugal clutch for low rpm operation. I imagine if the seals go it will have no problem siphoning from the lines or sucking in oil splashing around in the crankcase.

Also, the turbo lube breaker has a cover to keep it from accidentally being shut off.

I'm going with running. One of my bosses jumped from a locomotive once because he said it sounded like the turbo was going to come through the bulkhead.

[LateFan]

If you're assuming the engine is toast anyway, could you throw a switch that cuts off oil pressure? (then run)

[Exodus_2pt0]

You'd think they would build something into the air room, but nope. There's some photos in here of the air filter setup and the turbo inlet.

Ours are 3600, I think your typical freight engine is around 4-4500iirc. Still though, even on our little guys there's 16 cylinders, each with the displacement of your typical small block V8.

If I'm ever working on an engine that runs away, I'm bailing. Simple as that, I'll call the fire department and wait a few hundred yards away.

When guys tell you stories of pistons launching out of the block, through the wall of the locomotive, and landing some distance away.... well, Yea fuck that. It's bad enough having to walk directly next to the things during a load test at 900RPM and 26psi of boost. Talk about listening for any abnormal sounds. Luckily ear plugs cancel out the white noise and allow you to hear the things that matter.

[Exodus_2pt0]

Yup, bulletproof engine with a blown turbo providing fresh oil to the intake, and a 300 gallon oil capacity equals a fun time.

[jeffnhiscars]

Semi-serious question - could you throw big towels or blankets in the intake and smother it? Or do they get sucked into the turbo and make an even bigger mess? Or is it too dangerous to even get that close?

Never thought of it but next time I'm near a runaway diesel I'll grab the bong and comforter and let you know how it goes :p

I don't think it's hard to calculate the intake air velocity. I'm thinking Stargate for a bigger engine

Anyone ?

[LateFan]

Is this what you guys are talking about? Just keeps going.

[LateFan]

Sucks!
