This is great news.
Maybe now Lionel can finally get around to producing an Amtrak Genesis P42 instead of that nonsense they did a few years ago with the release of an Amtrak RTR set...
But then again (for those in the now, gladly correct me if I'm wrong), didn't Lionel inherit all of the K-Line tooling and instead of producing the K-Line product - some of which was better quality product (trains and operating accessories) than Lionel, just shuttered those items away into history... and high prices on auction sites when they show up.
Lionel briefly made a few K-Line 21" passenger cars, Milwaukee RD, Texas Special among others. The USRA Mikado, Pacific, 0-8-0, PRR B6 and A5 maybe the K4 are all K-Line tooling. They also own a lot of the Weaver tooling. Pretty sure their made in the USA cars are ex Weaver plus the 60' head end cars.
