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. All kits come with installation instructions. Please let us know the 6-number of the engine that is on the box. If that is not available then we need the Cab Number and a description of the locomotive. This information is needed so we can send you the correct parts.
