It's normal to the Lionel model and it's prototypical. I have the Burlington Northern version (1933081) and it does it. Here's a video of an actual SD40-2 making the noise. It's most pronounced around the 2:07 mark. Still annoying.

Yep, mine had a bad front coupler right out of the box. I had to obtain an RA and send it to Lionel.
