Hello all,

I've run into a problem with my layout I didn't anticipate using software to design it. I have a "tree" of K track 2262/2263 turnouts that ends up in such a way that two of the motors are facing each other...so there is not room for both. Is it possible to modify these to mount the motor on the opposite side? I am looking at under board mounting, but I am not sure if this will really solve the issue or not. Does anyone have any suggestions on how to deal with this? These turnouts exist in an area of the layout that is not easy to reach, so I need to keep them electric. These are the newest 2262/2263 with the "slim" motors, I have moved the older ones with the big motors elsewhere...

The highlighted sections in the attached image are where the motors collide.

Possibly, but not sure how much "downstream" effect that will have on the track replacement. Which ones support this? 2272/2273? Any others?

I may have been wrong about mounting it under the table...it might fit. Does anyone know how far the 7548 protrudes from the side of the turnout?

Hi Brandon,all,



The Märklin under base board mounting kit (7548) will only allow to 1" thickness.However you could replace the flimsy throw wire with music wire.

I think I found a solution to my problem, maybe this will help someone else. I mount one of the turnout motors upside down. I didn't think it would work, but after test fitting it, it seems ok. Since my layout "base" is 2" of extruded foam on 1/2" plywood, I have the ability to carve into the foam to allow the switch motor to sit mostly flush. I realize the motors won't be quiet parallel to the turnouts, but I don't think it's any worse than the derivation when wires get tucked under the motor running a temporary layout. What do you think? (sorry for the crummy iPhone photo, it's taken on a bit of an angle so it doesn't look flat, plus the lens distortion)

I do not think that overlapping the motors will work. It will not work reliably.
Avoid the underfloor mounting if at all possible - they are horribly unreliable.

Mounting the motors upside down works well. So well in fact that I dis that with all mine in visible areas. Even if access from below is restricted. See http://layout.mixmox.com/1/Switch_motor_thread for a solution in that case...

Are these two clashing turnouts critical for the planned traffic, i.e. will trains be coming from below or above in your track diagram? If coming from above, what about simply leaving one unmotorised?

Hi Brandon,

Check this link out. This is what I am going to use for my C track turnouts.
