Is it just me, or does it seems that there are more 2 car units on the line? It's bad enough at am/pm rush hours with mixed cyclist/commuter/longhaul travellers jostling for space on the 3 car units, but 2 car units......who came up with that idea?
I think it's related to this, since the only 2-car Turbos are165s:
I wonder why the 166s were sent to Severn Beach anyway? In the pre-cascadean era the North Downs Line used to have 166s to Gatwick and 165s* to Redhill. There's no difference in gearing (it's Chilterns 165s that are lower geared), but the interiors of 166s suit the airport run better (more luggage space, more seats for groups). Then earlier this year it was all 166s, until this month when we've had 165s on all the services I've seen.
*PS: these were always 3-car 165s then.
