Bachmann 2-8-0 #83604, brand new, makes "hiss" sound. Is that normal?

Hello gang,

I just bought a(BEAUTIFUL) 2-8-0 with belt drive and it makes a "hiss" kind of sound. I was wondering if that is normal? NOT a squeak or squeal, a hiss? It is my first new engine in a while so I am not sure what they are supposed to sound like.

Thanks

The Hiss may be Cylinder Blowdown. Try the fuction 4 button, that should turn it off.

Mc is right- if you are sound equipt...R U? If not, and the hiss is only while it is rolling, yeah, something is rubbing, try to narrow it down, and while you are at it, carefully oil all the places and parts that you see in motion, valve gear, the bottom where the axles are covered with the plastic plate, but don't take anything apart unless you know what your doing.... it doesn't smell like  somethings burning when you hear the noise do you? Might have to go back.... good luck.

Just a guess...mine out of the box had a dry bushing on the small,lower shaft with the worm gear....made a racket and left brass shavings around inside.....It got a free trip back to the seller for replacement as it had out of round wheels and other issues.

Could also be a wheel wiper (power pickup underneath that rubs the wheel backs at the rim) If the wheel back is machined rough or the wiper is bent wrong making it dig into the wheel it could have a "hiss" sorta.

Some good/some junk.
