That photo certainly shows some upgrades to their transportation. The last buses I saw were the small school bus configuration, and most had their windows open which led me to believe the A/C was not working.
This new fleet is certainly an improvement, and should be much more comfortable to travel in- once you get into it. Looks like it might be a tight squeeze when it gets crowded, and unable to carry the amount of passengers the small buses could carry. Still an upgrade, and the color code system should reduce confusion on the destination.
