After taking over 4 months to publish their final December 2006 timetable, FGW have just released a 7-page PDF file stating all sorts of weird and wonderful alterations to their train times booklets...

The ones which stick out to me:

"Delete Fishguard Harbour boat symbol on arrivals line"
"Incorrect page inserted. Monday to Friday times shown rather than Sundays from 1 April 2007"
"Camborne misspelt in station bank"
"Sun until 28 Jan 2007, 1245 Gunnislake to Plymouth add GW to operator" (What they forgot they were operating it?)
"Sun 2308x and 2354x at Exton move one column to the right"
"Add note CE to read The Cathedrals Express"
"Sun from 1 April 2007 add 1st class symbol to all departures from London Paddington at 45 minutes past the hour"
"Saturdays 1551 Trowbridge to Westbury. Delete this train"

How can they make so many mistakes, and not realise them until after the booklets are published?

A few points that actually matter to our section though...
"Mondays to Fridays 1917 Trowbridge to Westbury starts from Cheltenham Spa"
"Mondays to Fridays 0702 Westbury to Trowbridge terminates at Cheltenham Spa"
"Saturdays 0902 Westbury to Trowbridge terminates at Swindon"
They've actually been bothered to show that these trains don't just run between Trowbridge & Westbury anymore...
