Lionel's new Steam-Chuffing Diesel Engine feature is ... interesting

I hope mine isn't like that!

That’s not a chuff, that’s a knock in the Diesel engine ……clearly the knock has damaged that cylinder so bad, it’s developed a miss, ….hence the wobble ….you’ll be fine till you hear the death squeak,…..😁

I would say check the traction tires for high spots. Sometimes they need to be reseated. I’ve also had engines wobble on those rollers but no so much on the track.

sounds like an old Alco

Agree. Most of the time traction tires have a flat/low spot because the engine sat on the wheels in a Styrofoam container.

Put your chin on the bench and see if the wheels are rising  up and going down on the rollers. If it's quiet and doesn't wobble as bad on the track. I'd lube it and run the tires in.

They can flat spot again sitting on the rails in the yard. That's why my engines all get shelved on the flanges when not in use.

Sounds like a typical GE idling.

Rod, note that the engine was not moving, so it has nothing to do with the traction tires.

It's on test rollers.

You are lucky it's a Lionel. If it was a Weaver steam engine, it would have catapulted itself off the track by now.

Lionel never fails to amaze me with their advancements in technology. They've brought real life diesel engine failures to O scale!

It does not sound like any steamer that I have heard; more like a large four-cycle Diesel idling to me.

Ah, I didn’t notice that! I stand corrected.
