Well I have ventured away from the tycos, and explored the outside world of scale modeling, rivet counting, identical prototype paint schemes and unit numbers, and have found myself coming full circle enjoying tyco trains and reliving my childhood, with my children. So, now I remember some of the problems I had, such as the smell of the hot motors. What am I doing wrong, well, other than getting trains out of the boxes and running them. Is it the brushes on the motors going bad? Help!!!

Hi Foster, and welcome back.  I too bounce between the scale stuff and the just-for-fun stuff., but proto-modeling has gotten very boring for me of late.
That odor is generally from oil and dirt on the brushes and commutator. A little is okay and will burn off, but too much and it stinks and begins to result in sluggish performance. That's especially true for the Powertorques, since they are high speed, low torque motors and gummy brushes can stop them dead. You can soak the brushes in 90% alcohol, and clean the commutator with a Q-tip if need be. Just go sparingly on the oil if you reapply it to the bearing on the brush side of the motor, cause it will sling back onto the armature and you'll be back in the same boat. Be sure to remove any old grease from the gearing as well, since it turns to hard wax.
If you have Tyco engines with 5 pole motors, they are much more robust, but it doesn't hurt to give them the same treatment if they've been in storage for years. With a little tuneup time you should be good to go.
Hope this helps.
