I had heard that was an option, but didn't recall hearing it was a done deal. With spares that is only about 7-9 sets of equipment though, I am assuming, with less seating capacity?

Is there any word on when they expect delivery and completion of the order? With older equipment that is now in service needing overhauls over the next couple of years, that still won't leave much "new" capacity to increase train size or service levels very much.
