I have an MTH PRR K-4 that has worked fine for a long time but after sitting in a box for the last year untouched it now won't run. The wheels are locked up and the motor sounds like its trying to go but wont move. What could this be and how could I fix it? I was supposed to run it tonight at the town Christmas gathering since my friend and I set up and run the Christmas train display for one of the local businesses.

Mostly like the battery is dead.... try a new battery or try charging it on the track for as long as you can......
You can't turn the wheels by hand, that's normal, but you should be able to turn the fly-wheel on the motor.
that;s my guess, dead battery
Also lube the center rail roller pins, the pin that goes roght through the roller. At this late date use what ever you have... 3 in 1 ..WD 40 use sparingly
Try oiling the axle bearings.
Check the grease in the gearbox. It can congeal when a locomotive is stored.
