I received an SD-45DCC "BeeLine" for Christmas.  I am running it on my DC layout.  I ran it to check it out and it makes a lot of noise. The noise is a low pitched whirring/rumbling sound and you can feel the vibrations through the table. Don't think this is supposed to be.  My son and I installed the dummy plug in the decoder thinking it might help eliminate the noise but it did not.  My Atlas loco is many times quieter than this one.

Any advice appreciated. I might have to send it back if nothing stops this unusual noise.
