Hey everyone I am builinding a mine cart system that splits off into a T. At the entrance of the mine I have made a switch that you can switch on or off so the T on my system will switch to left or right. Now the only way out is to go back to the entrance so the minecarts have to turn back out the same way they came in. Now if no one has hit the switch while someone is down there they can come back no problem. But lets say I hit the switch went down and then someone else hit the switch and when down to the other way and then I wanted to come back up? I have been trying to figure this out by using detector rails so whenever you come back you automatically go back to the entrance. Anyone know a sure fire way of doing this?

I can link a detector rail to turn off a redstone tourch and get it to turn the correct direction coming from one side but if the swtich is already sending a current to disable the tourch is there any way I can use another detector rail to turn the tourch back on while the other current is still active?

Certainly easy enough to do, a simple switch will work. I think if you look of "T-Flop" style switch it will work for what you need.

You could also make use of jumping carts. You can drop onto other tracks. Just have the "In" carts dropping onto your "Up" track, which goes and drops back onto the main track. No redstone switches required at all.
