TMCC Upgrade Kits.

Lionel TMCC upgrades for engines that originally did not come with Command Control. Electric Railroad upgrade kits from ERR by 3rd Rail. Call or email if you are not sure what you will need for your upgrade. Your engine may run with an AC Transformer but that does not mean you need an AC Commander. It depends on the type of motor that is in the engine. We can upgrade your locomotive if you are unable to perform the upgrade. Kits are in stock.
