Good Evening,

Today I received in the mail a brand new MTH Premier ES44AC and its making a clinking noise.  I originally did not hear it due to the engine sounds / crew talk, but when I turned all the sounds off the clicking was obvious.  I did not touch / move the locomotive while it was idle.  

Any advice?  Is this normal?  I apologize for this question, this is my first MTH engine.

Thank you for your time-

Turn the locomotive upside down and thoroughly look at all the wheels, gearing, etc. on the underside.  Something may be rubbing against the gears/wheels or truck side frames.   A traction tire may be off the wheel. Power up and run the locomotive upside down where you can look at the powered trucks.  What do you see?

Thank you guys so much for your input, the engine is under warranty so I don't want to mess with anything right now, but I appreciate everyone's help.

I did check everyone's concerns, the sounds were off, the traction tires are intact, no obvious signs of rubbing, center rollers appear normal.  I will do some more homework and yet back to you guys.  Thanks again-

One other thing you could try is power down your layout.  Lift the loco ever so slightly by hand to reduce the drag from the traction tires and pull it down the track. If you still hear the clicking you know its the rollers.

Then you could do the same with one end completely off the rails and isolate which roller it is.

 

There isn't necessarily visual evidence of a defect that causes a roller to click. I received a a newly released caboose that has a clicking roller as well. I'm not sure if theres a flatspot on the inside of the roller or what, the roller looks fine.

Either way its merely a nuisance and nothing else.

I've found a drop of electrically conductive oil like Bachmans EZ Lube or Atlas' Conduct-A-Lube reduces the noise and it fades with run time.

Other than that, replacing the roller assembly is the obvious remedy, provided the replacement dosen't click

Thanks! Have some of that and will try it tonight. Will try that Jeff.
