I had a opportunity to update a Lionel Flyer S Gauge Polar Express set by installing LED's in all the passenger cars and I modified the Baggage Car to look more like a XMAS Baggage car. I also installed LED's for the Marker lights on the Observation car and it gives it a different look. On the video you will also notice that the engine is a Lionel Flyer SD60 painted in "Honoring our Veterans" like NS did on their engine. See the video on YouTube https://youtu.be/p_scEMf7E1w
