Stand-ins of a different type are inevitable on the X21 considering all of the B5TLs form part of the allocation so only takes one to be missing, looks worse with all the 16 plates of similar spec now being sent to Washington depot which only really leaves the ex Lothian B9s and OmniDekka's left to allocate, 6331 is another (maybe 6332/3 if they return to CLS in future?).
Much the same story with the also apparent unreliable Xlines X20 Citaros, looking on bustimes.org, only 5330 was missing from service yesterday (which hasn't been out since March 23rd).
I think the sudden obsession stems from some posters on this forum spending far too much time monitoring BusTimes for any anomalies in services, then posting as fact as if they've witnessed it with their own eyes.
