the shell (?) of this loco resonates or vibrates when running. Has anyone else had this problem, and has been able to rectify it ? Thx

How old is it? I’m not aware of any recent SD40-2’s from atlas.

There is however a thread that was running today regarding noisy Atlas loco’s

Bruce, Atlas has never made an SD40-2…could you have a GP40-2 or a GP38-2? You need to be very specific on the model. Or is it a Kato SD40-2?

Or maybe the Athearn SD40-2?

Or even BLI etc.

I suggest showing a pic. That with the road number usually tells.

my apologies, it’s Kato.

Bruce, don’t know what to tell you. I have a grand total of 27 Kato SD40-2’s mid production diesels and I have no problems with resonating or any other noise with them.

Time to remove the shell to see if something came loose [:-^]
