    Is there any way you can use cables (model aircraft etc) to transfer the movement from remotely positioned machines?

    Well, I've been looking at that. Not sure if I have room inside the control panel, under the table top. Been thinking along those lines... Thanks for the suggestion.

    In line with Toot'ns thinking, there could be a way to make this work, despite the frame work. What I am thinking works on a "push/pull" wire like an old style "Choke" in a car. You could install "Push/Pull" switches in the facade of your bench work or a separate panel for them and run heavy weight wires through the frame work to where your gates and or turnouts are located. You'd need to fabricate a linkage system from the actuating wire to the cross bar for the gates and or turnouts.

    Come to think about it, you don't need to have your slow motion machines directly beneath what it is you want to use them for - they too can be located away from the gates or the turnouts and use them in the same manner as the "Push/Pull" manual choke method.

    The advantage of the cables and tubes used in aircraft etc is that they use nylon tubes, which have less resistance against the wire than a choke or bicycle metal tube. Actually I think even bikes use them now. Pretty sure you would also find the cranks etc that you may need in the aircraft sections of hobby shops, or online. The main trick is to keep any curves as less as possible in the runs.

    I did the crossing video. I used a new video editor so it took a day or two to lean how to use it. Notice how slow the gates go up and down. Their a little out of sink. I'll fix that in a day or two. Enjoy the video. A fast moving freight. I added a sound track I recorded while having my car's oil changed in Rockland county, NY.

    George,

    Darn, great little video mate and that was some train! As for the gates, the object of the video, I thought they went up and down nicely, not too slow at all. They look great and glad you got them working - excellent work!

    Then there are also "liquid levers" where one could use a syringe on either end with a plastic tube between to do a push/pull hydraulic arrangement. The nice thing about that arrangement is that one actuator could control multiple (in this case two) rams, one for each gate.

    Horseman,

    That's an interesting idea and goes to show there are many ways of "skinning a horse"

    Thanks, all! When I have time, I'll look into the various possibilities. Meantime, everyone have a Happy Holiday Season and a Happy, Healthy and Prosperous New Year!

    trailrider,

    You too mate and I did hear back from Suzie. A bit more to connecting up servo's than I remembered. In addition to the servo's you'd also need a "Signalist SC2" which the servo's are connected to and that, in turn, is connected to the power source. The SC2 can handle 4 turnouts per unit and cost around $45 each give or take. In so far as sped control is concerned, the SC2 is programmable for the speed of the servo by changing CV numbers in it.

    While it is a good, solid and reliable option, the over all cost maybe prohibitive when compared to conventional methods.

    At the end of the day, this is pretty much mute as you have your gates working very well.
