I don't think that they'll ever totally replace the Flyers until the Silver Lie is all set -- they wouldn't want to fully convert the service to the new TT's, then have to pull a bunch back out a few months later. Although....
Commuters might actually like that. Sure, the Neoplans ride better, they have AC, and they're a lot cleaner, but, the lack of seats is probably going to annoy commuters in the long run. So far, I've taken 5 rush hour trips on Neoplans on the 71, and I've only gotten a seat once, and that was boarding at Harvard (I almost always get a seat on the Flyers, even at rush hour). Even late night runs are SRO now. Losing 13 seats per bus really hurts. At first I was eager to ride the new ones, but now I'd much rather see a Flyer coming down Mt. Auburn in the morning -- at least then I can sit down and read the paper. And, despite losing all those seats, there doesn't appear to be substantially more standing room in the buses. Its still a struggle to get to the front to exit (which you have to do on the outbound), which is compounded by the fact that there are stairs to negotiate (after all, if you sat, most of the seats are way in the back), plus an extra 10-15 standees that would have been sitting on the old Flyers.
Sadly, whateveer ability these buses have to offer nicer amenities (AC, ride quality, ASA), will probably be a net loss in the eyes of average commuters due to how poorly they handle crowds.
But they are taking over. This morning, my Flyer was behind 4116 on the 73 inbound, and 4117 and 4110 were o/b on the 71 and 73, respectively. There were at least 4 visible outside the Watertown carhouse Sunday night, but I coukdn't see numbers in the darkness. There were two in the busway area, one in front of the building, and one outback missing some rooftop components.
Wondering if I'll see the Western Route double-tracking finished before I retire...
