I picked up this combination from them a while back. They also have videos on the website showing the engine and passenger cars.
I had been eyeing this engine for some time from the original time it was shown in the Lionel Catalog it looked pretty sharp in the blue with gold trim. I really liked the Blue in the catalog photos was a bit disappointed with the color when it arrived that it did not look at nice as the catalog images. But I still love the set overall the colors still look great. The passenger cars match the dark blue on the roof of the engine and side # boards. It is a great looking set one of the better color schemes in trains and the LionChief App on the phone is fun to run the train. Good smoke output, nice sounds very nice slow chuffing sounds. Here are some quick photos sorry could not get more in focus.
