| CSX Heritage Fleet |

Hello All,
Since CSX got on the band wagon and has been painting their heritage, I figured why not start a thread for those that have caught them out and about. Sadly I am to far north to be able to get any pictures of them. The closest CSX main to me in Sandpatch grade and that's over an hour away from home. But that's neither here nor there. I know some don't like how CSX painted their engines but each railroad is different. Anways, if anyone has pictures of them please post them for us to see since we have threads for other railroads that have heritage units.

| Bowser DC-71 motor |

Hello all -
I recently picked up a 25+ year old Bowser 2-8-0 kit. It has the DC-71 open frame motor.
The kit has gone together well so far, but upon opening the motor I noticed lots of "magnetic dust" on the magnet. I cleaned as much off as I could by vacuuming and compressed air. Upon bench testing the motor detached from the chassis, it is overloading my Tech II power pack almost instantly when I get above 1/4 throttle. When it overloads, the motor is very hot (more than just warm - but not to the point of smoking). I know these motors are current hogs, but I think this pack should be able to handle it. I cleaned the commutator and brushes, and the armature spins freely. The armature does not look damaged at all from a mechanical standpoint. I tried replacing the magnet with neodymium magnets, but the result is the same. The motor otherwise starts fine and runs smoothly at low speed.
Anything else to check here before I call this motor dead? I may fiddle with the spring strength on the brushes, but the only other thing I can think of is that the armature has a short somewhere in the windings.
Thoughts? I contacted Bowser, but if I have to replace the motor I will probably upgrade to a can motor to reduce current draw.
