Communter Rail between NOLA and Baton Rouge

I think it is a great idea if and only if they go ahead with the airport that has been discussed between BR and NO. If the do the airport then the train would be excellent and would more than pay for itself. Would you drive your car to the airport and spend the gas money, wear and tear, parking and walking from the parking to the gate or ride the train? They could have a train that leaves every 15 minutes going each way and then have one direct line that runs from NO to BR and back twice daily.
