Above board turnout motor for Tillig advanced track

Above board turnout motor for Tillig advanced track

Postby Rich B » Sat Aug 31, 2013 6:26 am

I want to place a point in a location which is unsuitable for a below baseboard motor, eg Tortoise or Tillig 86112. The Tillig mechanisms 83531/2 don't look suitable for EW2s (the points I'm using in that area), and I'm not aware of any latching or stall point drives that are. Can anyone suggest something? I'd rather an electrically driven point than hand thrown as I like to have a control panel that I can move around according the the requirements of exhibition or home use.

Thanks

Rich

Yes, Tillig 83531/2 are not suitable for EW2 and EW3 switches.
They need a big force to move and hold the point.
For example, some Russian modellers told me that Hoffman's switching machines sometimes can not hold the point in place.

Some Russian modellers use polarized relays instead switching machines. Look here:

You can use a tortoise motor at a remote location. Sleave some piano wire through a tube and bend up an "L" at one end for the point throw bar. Run the tube/wire over to the point motor and bend the other end to fit the tortoise. You can bend a little zig-zag into the wire at one end to put some spring into it if needed.

Great idea Mark, that'll sort the issue out. Thanks!

Yesterday we received the first new handmade switches for our new TT layout. The new switches use flexible points, ie. to switch them you need a motor driven mechanizm. I decided to use in the future only servos for such jobs. In my H0 logging railroad i tested those servos, that time in simplified way - I just removed from the motors the electronics, and controlled the motors with simple DC power.
On the new layout we plan lot of switches, so I was looking for a more efficient way. Today the servos are very cheap ( for our puprposes the cheapest ones are more than good enough).
How to control so many switches? I found a solution with the Octopus III.
This device for reasonable price can control up to 8 servos with lot of features what are unknown from the model railway industry. You can control the speed and the angle of the servo mechanizm.
For the control you can use any common devices like pushbuttons, toggle switches, relay contacts or external control signals +5V.
The device delivers also signals for 2 position indicators. You can also combine the diverse control methods.
For computer controlled layout you can attach an extra DCC decoder, or you can use the GPI signals to throw the points.

Here are the common informations for the control mechanizm:

And here are my first TTe handmade switches:

Servo control is getting simpler for model railway applications, with off the shelf decoders which also accept push-button control. I'm a member of MERG, who offer kits for controlling four servos via switch or PC for £6.30, and a simple kit controlling a singe servo with a potentiometer for £1.86- this one is actually simple to make at home as it's little more than a 555 timer, resistors and capacitors.

I do not use DCC yet ( too many old stuff) but I made many years ago a computer controlled layout based on description in the MR, with conventional parts ( the first version was controlled by a ZX Spectrum - because of easy graphics on screen). Anyway I probably will use those IO cards ( i should have over 128 ports), but this is a future music. What is funny on the Octopus is the control of the servos.
I use also simple servo controllers, based on one CMOS logic device and the potentiometer. For many switches it is too complicated to adjust each turnout individually.

That's pretty cool! I've bookmarked their website.

I had to replace the video, because the controller on the video differs from the original.

Here is the new link.
