I have seen the comments aimed at me. Unlike anyone else who posts on here, I live on the route. I posted an analysis a while ago, which echoes what Transdev have said. I said that outside the peak times and beyond the ring road, there was little trade. The previous MD wanted it and threw resources at it. He left and so did they. Currently it has some of the oldest buses in the fleet. They slowed the route in terms of timings. The peak times have the same timings as the late evening services, so the buses just sit around at timing points to lose time. They ditched the limited stop service, which slowed it further.
As to Connexions, yes it would be inconvenient if there were no evening buses, as it would mean that a £2.50 bus journey becomes a £35 taxi, if you are not using the car, but at least the taxi does the journey in half the time. However, East Keswick Parish Council have been vocal in the recent past about the inadequacies of the service, and the impossibility of enjoying a night out in Wetherby. As a result a recent trial saw a last 99 from Wetherby operate via Linton, East Keswick and Rigton Bank and then went back to Starbeck via the A58, so that Council would not just accept a 98 service, as it would leave East Keswick isolated. Linton is a 20 minute walk, a large part of it in the dark, as there are no street lights in Linton, and no pavements either for a large part of the route from either Wetherby or Collingham.
I have previously mentioned a shuttle service for Linton and East Keswick to the 36 at Harewood, but that was when Transdev were operating both routes. Whether a rival operator would be so keen to hand over trade to another operator is unclear. I suspect that the shuttle would be back to Wetherby and may have to be funded by Metro. Connexions would probably be the only candidate. They ran a Solo as a shuttle into Wetherby from Linton, when Linton Bridge was closed for a long period, a few years ago.
People mention the 7, but that only operates once per hour, for most of the day, is even slower than the 99 and goes nowhere near Collingham, Linton, East Keswick, Rigton, Bardsey or Scarcroft.
