How can I find out how full a dispenser is?

I'm making a roller coaster with minecarts. If I press a button, a minecart will come out a Dispenser (all underground) up onto the rails.

But after a while (when the Dispenser is almost empty), I want that the Dispenser will fill up again. For example, I press the button, a minecart comes out, then automatically a Minecart will be added to the Dispenser. Then it'll never get empty.

Is it possible to do that? It sounds at bit complicated but maybe it's possible...or not? I'm not sure...
