Bachmann 2-6-2?

[Danimal]

Did Bachmann ever make a 2-6-2 in large scale using the same tender as the 4-6-0? 
A local restaurant is having issues with their ceiling train jumping the track.  I'm trying to identify the engine to see if maybe there are known issues with it running on tight radius track or something else.  The restaurant was busy at the time so I couldn't really do anything. 
This engine is black with copper colored boiler in UP livery.

Apparently it is a Buddy L. Railway Express Die Cast Engine.  It shares a lot of parts with a Bachmann 4-6-0.  Did Bachmann build this for Buddy L?  Any known issues with the Buddy L. engines?  Especially that would cause tracking issues in curves?

I think I will start by assuming the pilot is a similar sliding design as the old 4-6-0s.  So I will see if the wire or screw or something is causing binding.  Might just need some grease.  I doubt it will be that simple though.

Dear Dan,
These "Buddy L" items were unauthorized knockoffs. Even the name Buddy L was
taken from high-quality metal models made many years ago.
I have no idea if our parts will fit their trains.
Thanks!
