I've been looking over the timetables published for this line over the Easter period.
I note that for the period 2nd April - 6th April all services passing through Reading West to Reading have this segment of the journey timed at 13 minutes. This is usually only 4-5 minutes and indeed the services running from Reading through Reading West over this period are still of that order.
Even the replacement bus service on Sunday 7th is timed at 10 minutes.
Does anyone know of any funky routing or other reason for this ?
With this being an hourly service too I'm tempted to drive.
