"Delivery of the 53 buses shall begin approximately at the beginning of May 2012." Wow, they're serious about replacing the 1600s quite a bit sooner (12 years) than they had replaced the 1500s (14 years). Didn't see this coming. At this rate, we can even expect the 1800s to be replaced next year.
And I hope you're right that 2700s is a typo -- it doesn't really make any sense (and the 2700s are one of my favorite fleets!). Let us know what you hear!
