Bachmann DCC 70t Shell Rattling?

[martin_lumber]

Hello All-

I have 2 new Bachmann 70t's, and each one was bought from a different store. One of them runs nice, and makes no noise. The 2nd one makes a Athearn-type noise. I took the shell off, and it makes no noise. I found out that if the shell is at a certain point on the chassis, it doesn't make the noise. Is this rattling? How can I fix it? No matter how tight the shell is, or how loose it is, it still makes the noise. Maybe the Bachmann department has some advise.

i've had some sucess by taping the inside shell with masking tape...
