>>>I have always thought about a turntable and wanted to know the pros and cons and difficulty involved with installation of a turntable. THis is a 24" Atlas #6910. The store where I inquired about the Atlas said he was not sure exactly the difficulty and how exactly track ( scaletrax ) would work.<<
I've had the Atlas turntable installed at least 10 years now. Ain't nothing prototypical on my layout so it works for me...I installed it against a wall so the footprint is small.
Other then replacing the flimsy rubber band drive twice and having the storage tracks maintain the DCS signal, its been problem free.
Today, to avoid signal problems I only keep TMCC/Legacy engines around the table and yes, having a storage track directly opposite a entry track, (there are 2 entry points ) I can run the Legacy Big Boy right over the 24" table and into its own spot on the other side.
