Don, You know, now that I think about it, you _may_ be able to
accomplish this by using an isolated outside rail track section. I would have
to see the track layout to know. Do you have a photo or a diagram? -Mike From:

Of don448@aol.com Thanks Mike. I came to the
awful conclusion that those were my options. I feel good that my analysis
was backed up by knowledgeable club members. Thanks for the
response. Don -----Original Message----- Don, I understand the issue. The answer is more track between
switches, or shorter trains. What you are looking for is a delayed
switching action (waiting until the last car clears). Unfortunately, it
doesn’t work that way without electronics. -Mike From: ttat-members-owner@aoot.com [mailto:ttat-members-owner@aoot.com]
On Behalf Of don448@aol.com Scott, Thanks for the reply. I have to
study it further, but if what I think you are saying, the two switches are
activating simultaneously! My system is working that way. That is
my problem. The tail end of the train is not yet over the second swtch
when the first switch activates it. The system works great as wired if I
have a short train and the final car clears the second switch before the first
switch activates. My problem is with a longer train, then the end of the
train is still on the switch when it activates. I think my wiring is
correct. I'm just trying to get it to do something it can't. I was
hoping for some jumper wire fix that would prevent the switch from activating
while there was still a car going through it. When the train starts into the
switch, it is in the correct position, its just that the position is changed by
the train going through the first switch causing derailment. Don -----Original Message----- When I have done this I used it in a figure 8 set up. What
you want to happen is for the train entering from one loop to change both
switches at the same time and then go to the other loop. The as it
comes back around tot he first switch it auto flips to be correct as it enters
and switches the other to be the out bound on the other loop. Sounds like
it should work. Now for how. When wired together, as a train enters one switch it needs to turn
the second as well and then as it goes over the second there should be no
switching. Thus no derailment. If the outbound train on the second
switch is turning the first switch under the train that is the bad result you
mention. There are only two wires need to do this interconnect. these
wires need to either connect the same posts on each switch or cross
the posts. What you need is the second switch outbound track
let's say the straight leg, to be connected to the first switch inside
track, the curved leg. One post is connected to each of the insulated
rails on the switch. So as a train comes into the first switch curved
track it sets the second switch to straight. AS the switch goes out the
2nd switch nothing should happen to the switch and the train goes into the
outside loop from the straight side. Then as the train comes around on
the outside loop to the first switch it flips and also flips the second switch
to the inside loop. It should be a matter of connecting the control posts
together. the ground, third post is not needed, or can be connected
together. This should run automatic and not need a switch controller. For what it is worth. Scott On Fri, 03 Dec 2010 11:07:17 -0500 don448@aol.com writes:
