I have a long section of rail that I'd like to serve with a single minecart. If I left the minecart on the other end of the railway, I'd like to push a button to have it sent over to the station I am at.
Thus far I've been able to accomplish this with redstone and repeaters, but I've noticed that repeaters only work one-way; I've looked at some online documentation and have found a schematic for two-way repeaters, but it requires quite a bit of real estate and my railway is elevated high off the ground so I'd like to keep land (and resource) usage to a minimum.
Is there something I'm missing about repeaters? Is there a small schematic for making them bidirectional?
