The early P2K models have become swap meet material at times,and after long term storage,"Freeze" up or just don't run! 
In some cases a clean out of the drive trucks of factory supplied grease will be the cure.
Some of the early P2K's may have axle gear cracks,that render the model immobile.
Time to troubleshoot the problem,it's not a total lost cause.
1.Pull off the bodyshell and set it in a safe place along with any parts removed to get the shell off.
2.Put the model on a test track and apply power,if it seems to turn the drive a little bit then stalls,
most likely the trucks need to checked,remove the worm gear from both trucks,place the worm gears and drive shafts in a safe place!
2a. Apply power again to see if the motor runs freely now.
2b. Try to move the model with a finger,look at the gear on the truck,if it barely moves,that will need to be serviced
The model should move freely with the worm gears removed.
If you have worked on Athearn drives in the past,Most P2K drives are considered to an Athearn "clone"
3. Remove one of the trucks from the frame,then remove the bottom plate of the truck,you should be able to then remove
the geared wheelsets from the truck to inspect.
Have a container handy to place the parts in.
4. Inspect the axle gears for "hairline" cracks,you might need to use an "opti-visor" to see the fracture
5. Dismantle the rest of the truck,remove any grease and let the parts soak in a container of 70% alcohol overnight,
Have an old toothbrush handy for cleaning the rest of the old grease off.
