Just incredible!  Wow your layout and attention to detail are awesome!

UPDATE - I did what Johnathan recommended and now the loco works great again.

Thanks everyone for your input!

Thanks Johnathan!

I'm guessing that the steel rails are the cheaper of the two?

I've got the cleaner and oil ordered.  Should be here on Monday.

I'll post an update after I'm done.

Here's a couple of videos that I uploaded to help show what my loco is (and is not) doing. LOL

Maybe there's some crud down in the retailer flangeway, raising up an engine wheel enough to break contact.

No flangeway, as this is an oval setup.  (I hope my terms are correct.)

The problems occur in the same locations, no matter which direction the train is running (clockwise or counter-clockwise) or if it's running forward or backward.

I was wondering if there may be some corrosion on the drive wheels and how to clean them?

Still no luck.  I've cleaned and filed everything as stated in this thread. LOL

Thanks again Jonathan.
It doesn't run on the floor but it is on some felt sheets to look like snow.  I can't attach a small JPG so I can't show you the setup.
I'll check that tonight.

Thank you for the information!
I forgot to mention that I did clean the drive wheels when I cleaned the tracks.  I did clean them both again this morning and filed down that bump on the bottom of the locomotive.
It does run better now but there are a couple of spots where it stalls and if I put lightly down on the loco it starts to move forward again.

Hi,
First time post on this forum!
I am a new Bachmann Train owner, so forgive me if some of my terminology isn't accurate.  
I purchased the Bachmann Trains - Jingle Bell Express Ready To Run Electric Train Set - HO Scale in November 2019.  It ran great last year.  Last week we set it up again and now it stutters (at higher speeds) and stalls at lower speeds - in 2 locations on the track.  I have cleaned the rails with 70% IPA.  All of the rail/track connectors are good.  I can run just the engine (no cars) and the above problems happen as well as when I have the other cars connected.  The odd thing is one of the places that the engine stalls/stutters is the section of track next to the terminal/rerailer so I wouldn't think that it was a voltage drop - and it stalls right in the middle of that section.
