Delays for Easter rail travellers in southern England
Easter rail travellers in southern England face delays due to scheduled engineering work on the lines.
First Great Western and Southern rail operators both have replacement buses on some routes.
Chiltern has advised customers to check its website before travelling during the bank holiday weekend due to revised services.
But rail operators say the number of replacement buses has dropped 34% compared with Easter 2011.
On 7 and 8 April, two of the four lines between Slough in Berkshire and Didcot Parkway in Oxfordshire will have engineering works.
Trains on the Aylesbury Vale Parkway to London Marylebone line between Great Missenden in Buckinghamshire and the capital will be halted from 6 April to 9 April.
Other minor service alterations will take place on lines operated by rail companies in the region.
The Association of Train Operating Companies chief executive Michael Roberts said: "A significant amount of time and effort goes into making sure that disruption for passengers is kept to an absolute minimum on the small number of routes affected by improvement works."
