A good Berkshire history Ted and thanks for all your hard work. Just a few thoughts to add regarding Lionel's reissued K-Line Lima A1 demonstrator. Lionel released this model with an incorrect tender and has yet to correct the error (when I called their attention to this they basically ignored me). The tender it comes with is what I believe K-line originally released it with years ago. It appears to be a B&A passenger tender of sorts. The tender Lionel uses with its NYC L-2A Mohawk would have been a closer match to what the Lima A1 actually had so why wasn't that taken into consideration? Maybe I am being overly picky about things but when Lionel charges $1,200.00+ for a scale steam locomotive it should be accurate.
I do have the MTH Southern 2790 and the P&LE 9401 in my collection. Both are beautifully executed models and good runners with excellent sound effects. I especially like the Southern 2790 in its green and silver paint scheme even though it never existed in real life. Thanks again and Happy New Year.
