I JUST RECEIVED A K-LINE GG1 LOCO NO. 4912 AND ON THE BOX IT STATES THATS IT’S UPGRADEABLE TO LIONEL TRAINMASTER COMMAND. CAN SOMEONE TELL ME HOW TO DO IT?
There are companies and a few shops that will do the upgrade for you. Bring lots of cash.

You might try contacting http://www.traindoctor.com/ . They got all of the K-Line parts when Lionel took over K-Line distribution.
