I recently wrote about how the Rushcliffe Villager 2 bus route has now been discontinued. The RV2 is not the only Rushcliffe-based bus that has received some major changes; the Rushcliffe Villager 1 has been shortened, in that it now travels directly into Bingham after the villages rather than around the housing estate. In addition, in Radcliffe on Trent, there were a small handful of stops that the bus went past but now doesn't; the result is that these stops are no longer serviced.
The Cotgrave Connection and Keyworth Connection are the other two. Unlike RV1 and 2, they haven't received any sort of cut; rather, both routes have been equipped with new buses and have been renamed to The Cotgrave and The Keyworth, respectively. Both routes now appear to have the same class of bus as Indigo does but rather than the buses being indigo, they are aqua (The Cotgrave) and pink (The Keyworth).
The Rushcliffe Mainline is also supposed to be receiving new buses; both the RM and the RV1/2 routes inherited the buses from the now-defunct Rushcliffe Greens line. I'd be surprised if RV1 receives any new buses, however; I expect any used from RV2 will be transferred to it.
