ZONAL fares are being introduced for travel on London's trains.

From January, it will be easier to travel by rail from Greenwich and Lewisham boroughs because the pricing for single and return journeys will be based on the zones used for the Tube and travelcard tickets.

The new structure will help pave the way for Oyster pay-as-you-go passes to be rolled out across London's train services.

Trains minister Tom Harris said: "This brings seamless travel for London passengers closer.

"The new system will make train fares in different parts of London consistent with each other."

There are currently 97,300 different station-to-station combinations, with their own set of fares.

These will be replaced by just 21 zone-to-zone combinations, with a single, return and cheap day return for each.
