These are kits for Upgrading Lionel and other manufacturers trains that say COMMAND AND RAILSOUNDS UPGRADEABLE on the box. The kits from Lionel are no longer available. We have what you need to install the boards in your engine. Please let us know the 6-number of the engine that is on the box. If you do not have that number, the cab number and a description can help identify the engine. We only sell the kits when we install them.
