Im in the palnning stage of my layout and i have one thing i need some help with i have looked everywhere and cant find this.I need to know how much space does a turntable and roundhouse require.Im going to be using 2 of the walthers cornerstone 3 stall roundhouses and their 90’ turntable.
My main question is what is the distance from the back of the roundhouse to the farside of the turntable?
i plan to have several small engine storage tracks also
According to Walthers, the stall spacing is 10 degrees. A quick on-line search didn’t yield much else in the way of dimensions, so I’d think that you’d need to have the roundhouse on-hand to accurately determine where the front wall will be in relation to the turntable - a not-very-convenient way to find out whether or not you have room for it. [%-)][sigh]
If you draw a full-size circle to represent your turntable, with lines radiating from its centre at ten degree intervals (representing the centreline of the tracks), you can move the roundhouse around until the lines are all centered in the doorways or, if you’re lucky, someone who actually has built and installed this turntable and roundhouse can provide actual measurements. From the looks of things, you’d not be the only one grateful for that information.
I’m planning a roundhouse for the second level of my layout, using the same 90’ turntable with a Korber roundhouse. Unfortunately, I’ll have only 30" of layout depth, so placement of the building will be in a coved corner, with only the front wall fully modelled. Both sidewalls will be severely shortened, so the roundhouse will be more of a scenic feature than a place to store and service locomotives. I’m hoping to squeeze in five stalls, but would prefer more. [;)]

yeah my current plan is for a 30 in wide shelf also
I maybe able to modify a corner to fit it just trying to figure it out before i start building
Count on one of the roundhouse kits taking a footprint of 14X16" (16" across the back, including the little office or bay extension, depending on the model), and you can figure out what two of them would occupy with the changes as the angled bays are added to form a more-curved building. The 90 foot turntable is 13.5" in diameter, including the mounting lip.
A 90’ HO scale turntable and a three stall roundhouse will take up, effectively, 2.5 sq. ft, and that’'s with nothing around them…tight to adjacent tracks and such. If you want some yard space, a side-road, some radial outdoor parking tracks…you would be over 3 ft sq., much closer to 4 sq ft.

Thank you
Kinda looking like i may have build the corner out alittle bit like top train did in order to fit what i want
Hello I have the turntable but my roundhouse is made by Atlas and has 6 stalls. When I get home I will see how much space it takes up. It may help. Here is a pic
Have a nice day Frank
Nice setup
how does the walthers turntable work with atlas roundhouse???
Hello It works fine now. I had to remove the stock floor of the RH to get it to fit right. The spacing does not mach. One front side corner is like 1 3/4 and the other is like 1 1/2 from the TT .The TT works fine I have a old power pack that I use to turn it and I can stop it anywhere I need to. My biggest problem was getting the spacing from the front of the RH to the TT lip right. To far back and the end stalls would not line up to close and the middle would be out. The diameter of the TT and RH are not the same. That’s why the corners are not same distance from the TT. But the way it sets it works. I will measure everything and let you know what they are. At Least it a place to start. And I did put in a wood floor in the RH had to cut to fit each board. The bench in the pic is 5’ 2’’ wide and 9’ 6’’ long. Hope this helps Frank
I am matching the Atlas version of the three-stall roundhouse with the Walthers Indexed turntable, the digital 90’er. The angles don’t really work, so I did a couple of things, and they would work for you, too, if you don’t end up with the same manufacturer for both items.
First, I built an extended apron out from the bay doors. The Atlas version has about 2.5" of plastic ‘concrete’ apron to which their turntable is meant to be butted. I had to extend it by about 3", but with a plaster of Paris apron, and then I painted it. I set the plaster around tracks already in the bays so that the tracks are inlaid, ties covered.
The other trick, and you can do this as you need to with any combo, is to use a small styrene wedge against a tie just at the lip of the apron, but the part of the model of the roundhouse that comes with the kit. The wedge imparts a gentle curve in the direction you need in order for the best alignment between the bridge rails and those ends we are talking about. Attached is an overhead shot of my set-up showing the curvature I had to impart with wedges. The wedges were cut and shaped out of bits of tie I removed during fitting here and there.
You can see that the two outer bay tracks had to be curved away from the center one, but the alignment is very good, the curve not consequential to ingress and egress from the bays.
Here is my overall setup:

This is my Atlas turntable and Atlas roundhouse, as a reference point:
The Atlas turntable is very small, only 9 inches across. The entire arrangement, from the leading edge of the turntable to the back of the roundhouse, is just about 2 feet. The Atlas system indexes at 15 degrees, so that’s also the angular spacing of the roundhouse stalls.
crandle that is a very nice set up you have and thank you for the tip i am going to try to use 2 of the walthers 3 stall roundhouses with the walthers tt so i hope everything will match up good.
Mister Beasley thank you also that measurement will give me a general idea
i like all the set ups yall have shown me
Assuming you mean the 90 foot turntable (not 90 degree), some of the dimensions you need are available from the Walthers website (and the rest from their catalog).
http://www.walthers.com/exec/productinfo/933-2840
You can download instructions and a mounting template from that web page.
Unfortunately, because the Wathers roundhouses are designed for use with both the 90’ and the 130’ turntable, they must be set back a bit from the 90’ turntable – the center point of the turntable relative to the roundhouse is the same regardless of the turntable size, since the stall spacing is fixed.
“Cornerstone” could refer to either of two roundhouse models: 933-2900 (larger) or 933-3041. The latter is probably the better match for the 90’ TT, so assuming that’s the one you mean, the Walthers catalog suggests that you need a total of just under 25 15/16" from the center of the turntable to the outside wall of the roundhouse. The roundhouse is 14" deep.
Combining that with the dimensions from the template indicates a total distance of about 31 15/16" from the far edge of the tuntable mechanism to the back wall of the 933-3041 roundhouse.
Best of luck.

THANK YOU!!!
got what i need now i hadnt looked at the turntable for dcc nor did i think to but thank you you answered mine and im sure several other peoples questions.
Should be able to fit that how i want
