Bus 190 was in service yesterday and bus 169 is in service today, surely they'd use a 7900 instead of an Eclipse 2 to save the batteries, or is there a reason behind this?
They took quite a few MCVs off the 30 yesterday and replaced them with 7900s, presumably to give them a run out unless anyone knows different.
I don't presume to know the exact reason, but I know the 7900s aren't favored vehicles - you can see that by how few of the 50 are out on any day. Two of the three original buses on the 12 have been changed already today.
