Fence type corrections and additions

New fence at 1 Sherlock Road

Fixed an obvious typo in opening_hours

Based on aerials, platforms 10 and 11 at Paddington extend at least as far as Bishop's Bridge

181A Huntingdon Road is now a pile of rubble. Not sure about the substation though.

Tree 0579 is gone, but there's a new (un-numbered) one next to 0580. Also some grass around them.

Path has been removed (new turf has been laid in its place)

Tree number 0579 is gone, which is how the service road reaches JJ Thomson Ave

The sign at the end of J J Thomson Avenue that used to say "West Cambridge Site" now says "Cambridge West", so I think the site's been renamed. It has a Web site too.

A small patch of woodland

The patch of the River Skirfare around Litton is definitely intermittent. Other parts probably are too but would need to be checked.

Improvements to the lower section of Crystal Beck and the nearby footpath. Gates added, path and beck disentangled, some notes added.

Crystal Beck is dry at the moment below the pool, so tagged as intermittent. Also tweaked alignment to more closely match aerials.

Tidied up the tagging of some stepping stones

Surface tagging of Crystal Beck footbridge

The loop in front of the Queens Arms is continuous

Fixed a stupid mistake that I made

access=yes implies all modes of transport; no evidence that New Bridge is different from the rest of the road

7'6" width limit is plated "Except for access" at the Buckden end

Another missing tracktype
