Well-done videography, Gary. Seeing those neat-looking Berks reminds me of K-Line's contribution, and how they made New England road names, e.g., B&M, B&A, as well. Were your Berks upgraded or are they original K-Line TMCC/Railsounds and smoke? They look and sound as good as it gets.
If I remember right, Lionel and K-Line were using the same Korean contractor for diecast models in early 2000s? And then Lionel acquired K-Line's tooling and products after a lawsuit circa 2005 or so, making Lionel by K-Line for a while.
