That's another 2 vehicle types which have just gone out the Arriva fleet in the past week or so, the Optare Solo and Temsa Avenue.

Must say, can't say I'll miss either tbh. 

The Optare Solo (non SR) has really gone out, under the radar, since they were everywhere at one point.

I kind of hope a Temsa Avenue gets preserved, even if it is a warning to future generations.
