THE amount of on-train Wi-Fi data passengers can enjoy on Chiltern trains from Oxford to London has increased.

The rail firm said it had upped the allowance ahead of the opening of the line between Oxford and Oxford Parkway to provide an 'added incentive' for customers to use its services.

On December 12 Chiltern trains will run from Oxford station to London Marylebone twice an hour.

The data allowance per passenger has been increased from 75MB to 125MB on long-distance trains between Birmingham, Oxford and London.
