You are so right, Arnold! RailKing locomotives have always provided great value for the $$. Very well-made and dependable performers.
Even better is that for some models, MTH continued to add some nice details during the product lifecycle (smoke units added to certain diesel models, for example) without dramatic price increases, making them an even better value than the earlier versions, at least IMO.
This thread is making me re-think my recent decision to start selling off a good portion of my collection!
