(8 hours ago)Storx wrote The 35/X21/X22 are piss easy routes hence they've got a chunk of the battered Enviro 400's doing them without issue. The vast majority of the route is just pottering round Bedlington.

They're pretty much on the 777/X16 daily without issue anyway with the Pulsars on the 1/2 which probably says what's actually better.

I mean, the 35 doesn't go through Bedlington and the other two are barely there for more than 5 mins! I'd also point out that, compared to the previous pattern of the X21/22 interworking, the vehicles on there now either get 15 mins sit at Ashington each trip (on an X22) or a breather on a 35 between each X21. There's also no A189 blast on the X21 anymore.

I'd not read too much into the allocation of Pulsars/Streetlites, they're seen as single decks and allocated as such. That said, my understanding is that the Pulsar is viewed as a more capable vehicle, and the allocation of the Kelso X16s backs that up.
