Ed -

I just got one, haven't got it permanently installed yet. I've tested it and it works fine, but haven't programmed any stops or anything yet. The mechanism seems like it'll be OK. The motor is under the track on the table and drives a gear on one end of the table which meshes on a circular rack outside of the turntable outer rail. On the other end is just a wheel to carry the weight, so there aren't two gears to try to keep in synch. It seems to be a well thought out design.

It's not, strictly speaking, an N&W prototype turntable; N&W's maximum turntable length was 115'. But the extra 15 feet means if any visitor brings over a UP Big Boy you can handle it. Also, most N&W tables were either tapered girders (deeper at the center and shallower at the rail) or through truss bridges, and this one is a flat bottomed girder.

But it's like anything else - if anyone comes to visit my railroad and objects, its too darn bad. It's what I've got, and I like it.

BTW - an A was 122 feet long, and overhung the N&W tables on both ends. The wheelbase was less than 115 feet, so it worked OK. Lamberts Point only had a 100 foot table, and had a loop track through a roundhouse stall so engines with wheelbases longer than 100 feet could be turned. The loop track got a lot of use . . .

Hi folks

At a sale at my favorite hobby shop in Duluth this weekend I saw the Walthers "Cornerstone" 130' turntable. Having lost my Diamond Scale Constuction TT a while back, I looked itthis one up in the Walthers catalog and it seemed to fit the bill.

Big enough for an "A" and looking at photos in a few NW books seemed to match pretty well.

Any comments from anyone who has it? Mechanism OK? More or less true to NW practice?

Thanks as always.
