Per Atlas' Website, this Engine has EOB. 

Trust me.  That's the first run.  No cruise control whatsoever.

Now, the odd thing. I seem to remember the center wheel sets on each axle could be blind, or possibly flanged.  Might have been a set in the box for changing them out either way. Are all 6 axles flanged by chance?

Walmart_Tom made an interesting point about wheel sets being in gauge as well.  That could be the issue.  Maybe it's in-gauge for Atlas track but is having a problem other manufacture's track?

Fred,

That is what I thought based on the date.

Dave,

In general terms, early TMCC before Lionel added Cruise Control always slowed down on curves because having solid axles and having wheels with Traction Tires, the inside wheel and outside wheel are going the same rotational speed.  Like the squealing you hear when 1:1 trains go around curves, the engine will slow down because depending on whether the inside wheels or outside wheels have the most traction, they are trying to overcome the slowness (out side wheels) or fastness (of the inside wheels) and without the Cruise Control, the motor will be under more stress and will slow down.  Cruise Control counts the steps (or the motor amperage for ERR Cruise Commander) and adjusts the power to the motor to keep it at a constant speed.

For 1:1 trains, the squeal you hear is one of the wheels "slipping" on the rail as the other maintains traction.

So for the upgrade, look at the boards in the engine and snap a picture.  Then post it here and we can tell you what you will need for the upgrade.
