Hi all. I am using the 24 inch AtlasO turntable as a guide, and I am trying to figure out the roundhouse stall angles.

Here is my dillema. The AtlasO roundhouse seems to be too close to the turntable to look like my prototype, so buying it would do me no good. On my prototype you can fit one and one half GP9 diesels coupled together between the pit edge and the stall doorway. I need about a foot and a half of track between the edge of the turntable and the stall doorway.

Using the 24 inch TT, what stall angle do I need to be able to push the turntable further away from the Roundhouse? 10 or 7.5 degree maybe?

Hope this helps , its the track configurations for various numbers of tracks and angles. The dimension you want is "A". If I'm reading the second sheet correctly that is the distance from the center of the turntable pit to the doors of the roundhouse. I hope this helps. The smaller the turntable the larger the distance between the edge of the TT pit and the RH doors

That was helpful, thank you. Was this an old ad or something current?

Looks like if I want the distance to be about right I need 10 degree stall spacing. I drew out a full size plan and it seems to be about right. I thought there may be an O scale roundhouse kit out there with 10 degree stalls. I apppreciate the help!

There used to be a company out of Indiana called the Monon Shops that made a Roundhouse kit and other structures. My Uncle built the roundhouse and added Grandt Line windows. His Indiana Eastern Railroad was featured in O Scale News two or three issues ago. I built several of their kits 25 years ago. They were excellent kits for the time. I don't know if Monon Shops is still around or not. If they are I suspect I'll see them in Indy on Friday.
This spacing was prototype for the B&O and other railroads. It's the best chart I've seen on roundhouse track spacing and dimensions
