Lionel:  6-18589.  C420 Alco.  Lehigh Valley #409. 2000. Cab 1 Equipped.   First, I found this thrown in the corner unresponsive, upon inspection found the program switch wire unattached.  I soldered the wire back to the switch, reprogrammed the loco electronic e-unit to #8, serviced the gearboxes, put new traction tires on it as well as new rollers.  It runs perfect. One truck, and the fuel tank had some surface corrosion on it, I touched up the black and the hand rails as well.  Loco operates on 8-18 volts AC. It was tested on Legacy version 1.6, cab 1 mode with 275 ZW power supply. engine id #1.  Directional lighting works, both remote couplers work good.  smooth throttle, crew talk and tower comms in rail sounds. strong smoke driven fan unit.  The box was shot, but the insert is perfect and i saved the end flap Info. No book,   It's available free on Lionel support, I checked, alternatively I can email you my copy. It's a great Alco, runs well.   Study photos.  Thank you.
