New Atlas Turntable

Area pictured with an OT105, Diamond Scale 26 1/2" TT and Korber 304, (4) stall house, (304, 3 stall kit, with one additional stall, 304A).  Approximate 5' wide by 7' back of house to wall.  Additional detail, wood, was added. House floor is not part of the Korber kit(s).  

Atlas O Turntable and Roundhouse area

I don't see it in that space.

I played around with the idea of having a turntable and roundhouse using my track planning software, and I realized just how much space you need. With a 24" turntable, I came up with 4x6 as the minimum for both. If you don't use a roundhouse if you could get maybe 30" wide, you could have the turntable feel ladder tracks on the other side, plus use the turntable to turn the engine's direction. 

Unfortunately....I do not think it will work. Maybe consider the space for just an enginehouse. Jim (Bridgeboss) just sent out an ad for his new modular 2 or 3 bay enginehouse. This is based on a more modern design. In 24" you could do some nice scenery and detailing in that area with an enginehouse. 

My old layout my turntable and roundhouse took up a 5' x 8' area. They require a lot of space.

These are oh so ver6 helpful! I really appreciate you all taking the time to think and share about this question! 🤓👍👍👍👍👍

where did you see ad for the Bridgeboss engine house? it does not seem to be on his website. also anyone know their phone number ?

Probably not what you were thinking of, but the best I could come up with is a 18" 5-Stop Transfer Table from Ross Custom Switches. It has a footprint of 19.75"x22". 

I received an email from him a day or two ago ..

Here is a pic of the email....

I built a 30" turntable in a 32" X 82" area. The key was using curved track (054) leading into the engine house.

I'm planning a new shelf layout that will have a TT and RH scene as the focal point.  I have limited space so this is a challenge, but I was able to come up with a compact design using the Atlas TT and a Korber 320 RH.  Pictured below is a true to scale picture for my plan.  The TT RH peninsula will be 31" wide by 63" long.   I hope this helps.

Curved track...hmmm that sounds promising! 😲

A transfer table might offer some useful options too. 
Great ideas! Thanks!!

This picture shows the curves off the turntable a little better. 

That makes it look very possible using the curved track. Straight engine shed instead of the standard roundhouse. How did you calculate the curve you needed?

The whisker track spacing for the Atlas TT is 15 deg.  If you run your tracks into a straight engine shed the curves will be multiples of 15 (0, 15, 30).   The engine terminal peninsula in the track plan I showed could be as narrow as 26" using that concept and allow for at least 5 storage tracks.  

I considered that concept, but I really wanted the RH look.  The Korber RH is narrower stall spacing (10 deg I believe) than the Atlas RH (15 deg) so even with this concept I need 5 deg curves so bend the outer whisker tracks into the RH.  Its a compromise I was willing to make to get a more compact scene.

Great thoughts. Thanks!
