"Dan, I bought mine new in 89 and was not happy with the gearing."
I never owned one, but a friend was considering selling his as he did not like the way it ran. I thought about it as it is historically interesting, but after testing it on my layout, I decided that a 100 smph switcher was not appealing, even historically, for any price he would find acceptable. So, I don't have one.
I can't imagine why they made it that way; the old 700E Hudson was well geared, and was a contemporary. And a better switcher, if it came to that. Did Lionel in the 80's change the B6 gearing? The 80's 785 Hudson will run at calm speeds; I have one.
