I saw on the inter webs a few misconceptions that I think need to be corrected so that folks don't pass on an engine they like.
First these engines run in Legacy Command mode requiring a Legacy system, or Base 1L and Cab1L, or a TMCC system (TMCC functionality only). You do not need a smart device or a Bluetooth app. Same as any other Legacy engine.
or
They operate in Bluetooth control. All you need is the engine and Bluetooth App free from Lionel currently available for iDevices, coming soon for Android. Nothing else. You get command control for the cost of the engine. Features are limited to the Apps capabilities but they are pretty decent. You do not need a Legacy Base or command base. Engine and App. Simple.
or
They operate Lionel Universal LC remote. Using the LC Universal remote will operate the newer Legacy Bluetooth engines. Again limited to the capabilities of the remote. No other equipment is needed.
or
Conventional transformer control.
Obviously a layout and power source would be handy too.
While some of this may seem obvious believe it or not I've seen a few inter web posts saying you require Bluetooth to operate these engines.
