Walthers TT and Atlas Round house

Picky, picky.

Rich

I don’t know why Walthers calls it a Modern Roundhouse. A.T.S.F. San Bernadino Ca. Roundhouse very closely resembles the Walthers in 1941 pic.:

Take Care! [:D]

I agree with you, Frank. That Walthers Modern Roundhouse would be appropriate to house the Big Boy.

Rich

Rich,

I was also reading that the Walthers turntable 130’ bridge track was 18-7/8 inch’s in length and it would hold a Big Boy…yeah all the wheels, but part of the pilot and tender will overhang, especially on the Rivarossi Big Boy. [:D]

Take Care!

Frank

Well, as far as steam is concerned, 1941 was pretty-much modern. [swg]

Thats what they had to do with the full size Big Boys. (Cheyenne, Wy 126ft TT)

Help! I’m being attacked by both ends. NAW! Just kidding.

Take Care! [:D]

What is the longest train that will fit into the Walthers round house without the extension ?

Cannot resist the urge to correct. You mean locomotive, not train.

When I first got into the hobby about 10 1/2 years ago, I told the owner of my LHS that I wanted to buy a “C&NW train” like the one that I had as a kid. “Oh”, he said, “you mean a locomotive”.

Well, excuuuuse me. LOL

Anyhow, if we are talking HO scale, the stall in the Walthers modern roundhouse measures 17 1/2 inches from front to back.

Rich

OOOOOPS !!! My very bad

Of course i meant locomotive . When I posted that message I was writing excatly what my other half asked me to. So it was her amature mistake…lol

ok so back to the issue at hand… 17 1/2 inches so thats fairly long to handle most steamers anyway, I was thinking of saving myself the cost of getting an extension for my Round house and if I did own a big boy I could just have him sitting on a storage track in the maintenence yard.

So was I right in seeing in an earlier post that even a Walthers 130’ TT the tender wheels on the Big Boy will overhang ?

Does this post any operating problems while on the TT ? If so can they be corrected ?

BTW thanks for all the replies… Keep them coming…

The Big Boy, and all of its wheels, will fit on the 130’ turntable. But the couplers will extend over the lip, so resist the temptation to place workers on the lip. I once decapitated one poor soul.

Rich

Good idea!

I hope there was a Union workplace investigation into that accident!!![:D]

Can I place stall tracks at every point around the TT ?

Is there an area which is a no track zone ?

Tomcat,

Yes to both questions. The turntable has two…no track zones.

Should not put track there.

Take Care!

Frank

Yeah! It’s better than to have this happen. [:-^]

The Walthers “modern” roundhouse comes with the stall extensions (1 per roundhouse kit + 1 per additional stall addon kit). I clearer terms: for every 3 stalls you buy, you get to have one lengthened stall (2 short, 1 long). My roundhouse has 9 stalls (had to negotiate and addtional 1ft of space from the property manager, who asked for the additional 3 stalls to begin with) so I will have 3 extended stalls and 6 short stalls.

Frank,

That is better than the opposite happening which puts the locomotive in the pit and the TT out of service for several hours.

Yes you can still put tracks there, they can be display only tracks, but you will have to use the 0-5-0 switcher (your hand) to move trains (edit: locomotives or MOW equipment before someone corrects my use of trains) to and from these tracks.

BMMECNYC,

Glad you got the property manager straightened out on that issue. [swg] [swg]

Take Care! [:D]

I’m using SCARM to layout my new layout and will have to fit my Walther’s 90’ turntable, storage tracks and possible roundhouse into the space available. I’l be setting the tracks at 15 deg angles and use the Atlas roundhouse to minimize the space required. I understand I may have to trim part of the apron.

However for planning purposes, how far back from the edge (or if you prefer center) of the turntable is the front of the Atlas roundhouse set so that the tracks line up in the middle of the door openings?

Incidentally, I’ve built the Walthers 90’ from a kit. I know there are many who have problems. Admittedly I haven’t test it installed, but I have run it on a table. I’ve been using and plan to use a variable voltage. One needs to go very slow when trying to align with the tracks but I want to go considerably faster when making big movements. Unfortunately for the cheap power pack I tested, the current drawn by the Walther’s motor is so low that with the power pack even set at the lowest voltage, its either on at full speed or off.

The main problem with the kit is the molding of the bogey wheels on which the bridge rests at either end. The way they are molded in 2 halves, the centers are sgnificantly off. I spent a couple of hours filing down the wheels to get them round. My test was to run the motor and look for hesitations and keep filing bogey wheels until there aren’t any. Also some tabs on the large geared wheel caused the driver pulley on the motor to skip until I filed them into the tooth pattern.

I’ve recorded video but I haven’t put it together as I was waiting until I installed it.

Put the assembled roundhouse on a sheet of paper and use a straightedge to extend the track centerlines to where they meet in the middle. Where they cross should be the center of the turntable.
