Dan,
Except for some minor modifications, that's pretty much the same interlocking tower they sold as a kit 10+ years ago.
If you are wanting a kit, American Model Builders (AMB) has a very nice wood laser interlocking tower:
They also offer larger versions of interlocking towers and yard offices, as well as an kit for including armstrong levers inside your tower:
I enjoy the AMB kits because I can position the windows open, shut, or anywhere in between.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
I've built several of these and they turn out very well.

For $9. more you can get a few more buildings and a speeder!

Both are in stock and on sale.
Have Fun! Ed
Looks like it's only pre-assembled. They have larger signal towers in the cornerstone line of kits which go together fairly easy. I think they have 3 types of towers.

Does anyone know if the new Walthers #810 Trackside Signal Tower is available as a kit? I think it is sold under the Trainline line.
Thanks!
