The ever-changing nature of expected fleet allocations at Arriva has been difficulty for us to keep up with, and usually as soon as we put something in print, the opposite happens. There were plans to allocated the 7 ex-London "ENR" class to Kent depots, the plan then changed, but two have found their way to Northfleet regardless.
4154 was captured (sadly not with full destination display) on the 491 at Gravesend Bus Hub on 23rd April, departing to Riverview Park. Those with a keen eye for fine details may notice that in comparison to stablemate 4150 (posted here on 1st April:
