Gunrunner John, I'll take "I Screwed It Up Royally" for $150.00. That's about what Lionel charges.
I am headed to the basement to bring the Allegheny #1604 to the kitchen table to work on it. Wish me luck. I am checking the gears and drive train to see what would cause the drag/ jerking/ binding between speed step 22 and 110.
I started another thread for the Lionel 6-82768 C&O Allegheny #1604. I had no luck getting it to work properly, but posted three videos of the engine and its problem.
Thanks again.
Sincerely, John Rowlen
