WOW! At least that is what I said after unboxing this beauty! This is a very nice, slightly reduced in size K-4 PRR Steam engine. It has fantastic detail, for it ALL to be molded in only. Two guys occupy the cab. It is well detailed, and has a proper throttle handle, in addition to a flickering firebox. It has builder's plates added to the engine and the rear of the tender. Operates with Bluetooth, Legacy, Conventional, and TMCC. It has an added brass colored bell, a brass whistle, and 2 simulated brass pop off valves on the top of the boiler. Boiler shape is proper for a Pennsy. The engine has a nice headlight, and illuminated number boards up front on the side of the headlamp, with a pair of cast in marker lights. (one color I think) The front scale coupler is fixed, and not interchangeable. Paint, and "fit and finish" are top shelf all the way.
This engine also has Lionel Voice Command, and Odyssey II, and is a Lionel Lion Chief Plus 2.0. So one could say this engine is about universally controlled by almost any Lionel Remote Control System.
Since I'm living in a less than 10" by 10" room, could not test sounds or smoke output YET. I am hoping tomorrow to fit some fasttrack partly under the bed, and on the carpet outside the bed. I'll see if that works, and add an edit to state how the sounds and smoke are.
You can barely see my NOS yellow Belly C&O Hudson behind the K-4. Here are just a couple of pictures:
Sorry, my picture of the backhead didn't upload properly.
