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?

I'm not necessarily sure that it is the most space-effective solution, but it's probably the method for making it look the nicest, and it's certainly the easiest: Run two wires; one each way.
Edit: As a side note; if the stations are too far away from one another, what you are planning won't work in any case; and building a rail in that fashion requires a lot of boosters. (Depending on your need for speed a rail traversable by unoccupied or freight carts requires 5-10 times as many booster tracks as one for PAX transport.)
Unless this is an automated freight line a more practical and resource-friendly approach is probably to have a couple of extra minecarts in a chest at each station.
