This is how it works in Melbourne (actually, there is now a single company that runs the entire Metropolitan railway). Initially they split it into two companies each running half the city because competition. Because a train line on the east side of the city can compete with a train line on the west side. Now a single company runs both halves. I can't see how this is better than the government just running it.
