Creating minecart terminal stations are simple, but building minecart substations are more challenging. When a minecart is stopped either by running out of velocity or through a powered redstone brake, how can the cart be restarted?
There are obvious solutions to this such as set a solid block behind the cart and power the powered redstone rail, but this doesn't work if the cart is in the middle of a track. You can also put the minecart on a slope with a powered redstone brake and apply power, but this requires the cart to sit on a slope – which is awkward for a player to get into and out of.
So on a flat surface in the middle of a track, how do you get a minecart moving again?

Use two pistons, one on either side of the track, when you press the button to start the cart, one piston pushes a block into the track behind your cart, then trigger the powered track. Then the first piston retracts and the second one triggers, pushing the track back into place. Let me know if you need further explanation.
