Oyster PAYG extensions this January

The new fares leaflet is on tube station leaflet racks everywhere, though not yet online. It confirms the new National Rail route sections where Oyster PAYG will be valid from January, though they're not quite as expected:

• Grays to Upminster and Barking on c2c. This covers all their London stations, with the exception of their few trains to Liverpool Street where Forest Gate and Maryland still aren't covered.
• West Ruislip to Marylebone on Chiltern, covering all their London stations.
• Greenford to Ealing Broadway on First Great Western, but not at intermediate stations. This is a surprise, but since both already have PAYG for their tube services, no expenditure was necessary.
• All intermediate stations between Walthamstow Central/Tottenham Hale/Seven Sisters (i.e. the Victoria Line) and Stratford/Liverpool Street on 'one'. 6 of the 9 added stations are in almost-tubeless LB Hackney. The promised expansion to Chingford hasn't happened.
• Kentish Town to West Hampstead Thameslink on First Capital Connect. This actually happened last month for the launch of London Overground.

The brochure also confirms that both Southern and London Midland will be accepting Oyster PAYG between Watford Junction and Euston/Clapham Junction.
