Haven’t heard anything good or bad...although the price is a bit dear.
There is an MTH one on the same auction site for less than half of the Lionel’s price. I think that’s what I paid fo mine.
Look under “ MTH Operating Rotary Beacon 30-9033”
I’m not trying to sway you towards either brand, I’m just epically cheap. A lower price will always pique my interest.
