Here's the proof, and comparison to other services:



Because of the very thin service, any cancellation is serious.

This train has run 89 times in the last six months, in which there have been 130 weekdays.  28 of those days it was cancelled because of planned engineering, 2 because it was Christmas / Boxing Day.   So 100 "should" have run. 11% cancellation rate - a very high percentage for a weekday.

Like the old platform 1 at Westbury, it would look much better with a railway line next to it.

On what was just a plain old platform we now have this lot ...

It's in "Oh no - not AGAIN" territory ...  known as being a risky train. I will look at putting some numbers on it some time.

Oh dear, that post was so predictable Chris, I was expecting it 

Cancelled as the guard for those services is booked to arrive at Westbury on the 1C77 10:35 Paddington to Exeter St Davids service which is currently being diverted via Swindon. Not the first time that problems or delays with 1C77 see the Swindon services cancelled.

For the record, the points failure at Westbury yesterday caused the cancellation of the 2M28 15:15 Swindon to Westbury and 2M21 16:23 Westbury to Swindon services. The unit stayed in the bay platform at Swindon and became the 17:35 departure to Westbury.

To really answer that you would need to know how often that service runs on a Sunday's via the B&H^▸ (Berks and Hants - railway line from Reading to Taunton via Westbury)

Only 2 trains in GWR^▸ (Great Western Railway) area cancelled through lack of crew ... guess where

Cancellations to services between Reading and Newbury
Due to a points failure between Reading and Newbury some lines are blocked.
Train services running to and from these stations will be cancelled, delayed or diverted between Reading and Taunton. Some stations between Reading and Taunton will not be served. Disruption is expected until 13:15 29/04.

A few diverted trains resulting.
