Arriva are probably going to simply get rid of all the oldest Pulsar's first, but they should really try and do it in a more thought out way than that.

When they got rid of the Optare Solo's, they also got rid of the oldest first (08 plate), which meant some really reliable vehicles like 2812 and 2837 went, whereas some newer (59 plate) but much less reliable vehicles stayed, like 2855. I would rather they had a look across all Pulsars, and if there is some newer ones, say 61 plate, which are causing a lot of bother, they could withdraw them instead, and keep the most reliable older ones. It shouldn't just be about age, they should take into account reliability too. Like 1497 at Ashington 61 plate, seems ok on the local stuff but breaks down on the express work, if there is an older reliable one, keep that instead.
