Here's my new Lionel Legacy Southern Pacific F7s, I bought them in an AA set with the powered A unit and nonpowered A unit. I bought them from Wholesaletrains.com for a great price. I'm really pleased with them so far, the sounds and details are awesome.
Here's a video of them: https://www.youtube.com/watch?...amp;feature=youtu.be
Feel free to share pictures or videos of your F units.
