2235, 2240, 41, 51, 55, 57, 60, etc. Less than 10-15 in the fleet total.
While the SuperLo are delivering slowly, expect the goal target for next retirement batch will be the 2005 model (2267 to 86). 2268 and 76 have retired and sold!
They haven't start 2500 series yet, most likely next year. The 81xx series isn't there yet, another couple years.
