Operating Accessories are just so cool. I intend some day to have a nice "scale" layout. But while attending train shows and watching the layouts (and other attendees reactions) I gotta say the "moving parts" of the layout always grab the attention. So while walking around a show this year I saw this for sale and the next thing I knew the wallet was out. Interestingly while carrying it back to the car (just this, no box included) I got "thumbs-up", a couple of "cools" and smiles from other attendees.
I have mostly Scale Steam Locomotives, so was going to have a coaling tower on the layout, but this just "called me." Apparently my "Inner Child" is much stronger than my "Adult Willpower" to stick to scale recreation. Would having a Scale Trains running through a Plasticville Village make me a bad person? (Sorry I digressed.)
Anyhow what is your favorite Operating Accessory? Post a picture or better yet a video of it "in action" if you want. Love to see what you have.
BTW my definition includes; EZ-Streets / Super Streets, Amusement Park Rides, and scratch built moving parts of layouts, Etc.
