Has anyone else noticed that when either the Central Line and/or the
National Express service is down between Liverpool Street and Stratford, the
TfL Journey Planner seems to refuse to admit to the existence of the No 25
despite it being the official recommended alternative route (rail
replacement buses don't seem to ever be laid on)? I've been recommended all
manner of bizarre alternate routes around the houses, particularly via
Walthamstow Central/Queens Road, even when the 25 offers a direct,
interchangeless journey.

Is this a standard TfL strategy or something exceptional for east London?
