Harrow right through meSlip away from London as dusk nears and head westwards towards Metro-land. Ride the train towards Uxbridge and you’ll see how once more the Underground offers some of its most tranquil sensations when it has shaken free of its titular lair. The line rises high above street level, poking its nose over rooftops and chimneys and the tallest of trees. Step off at West Harrow and you’ll find views worth lingering on the platform for.

Westward? Oh!The station building itself can’t really hold a candle to these provincial panoramas. It selflessly defers to its surroundings, helpfully distracting you from its less than notable design – only to try and redeem itself by co-opting the sunset into a kind of backcloth against which to display its tiny wares, like a thimble salesman setting up pitch in front of Westminster Abbey.

Look behind youI suppose there are worse examples of less used and even lesser loved out-of-town stations. But there aren’t many better examples of ones that make up for their deficiencies on the ground with such breathtaking sideshows in the sky.

I am not a number, I am a free man!

The sun always shines on Charles HoldenA bit of luck with the clouds, plus a bit of derring-do with the traffic, led to this picture. Granted, the station is strutting rather shamelessly in the light. All its finery is on display. But what’s not to love? West Kensington spends its life squeezed among buildings squatter in size and inferior in style, a plucky player in the jamboree of architecture that unfurls along the North End Road. Why begrudge it an occasional moment in the sun?

Go, West!Vehicles pummel the tarmac yards from the entrance. It’s possibly one of the least best locations for a generous slab of between-the-wars Charles Holden. You can’t fully appreciate it on your way in or out. You have, like an aesthetically-picky aircraft, to be on the right approach.

And one of these approaches is, to be granted, not especially practical if you’re hastening for a train:

Barbed remarksBarbed wire had to be navigated to take this picture. No, there was no trespassing involved. And there was no loss of dignity either – only a few stitches.

You can see how West Kensington dwells in less than exceptional street-level surroundings. But it’s always nice to come across a bit of the Underground’s lower anatomy exposed for perusal.

That’s a fine set of alcoves, as the draughtsman said to the stationmistress.

Nought but crossesFor the most part, all you get to see of the Thames while on an Underground train is its reincarnation as a cartographically-challenged blue line on a map above the head of the person sitting opposite. And even this wasn’t possible for a short period a few years ago, before wiser heads prevailed and all was soon again for the best in the best of all possible diagrammatically-realised worlds.

It’s even more exciting, therefore, when the actual Underground meets the actual Thames in the open air, which it does only twice, at Kew and here, by Putney Bridge station.

This is the Fulham railway bridge, whose splendour can be sampled either when you’re rattling over it or, and this is the real treat, ambling alongside it. For not only is this a rail crossing, it is also a pedestrian crossing, thereby allowing the spectator a close-up view of London’s two most agreeable forms of transport going about their business atop each other.

That’s not meant to sound voyeuristic, though frankly anybody loitering in a place like this with a camera isn’t exactly an innocent bystander. And yes, I did have to do quite a lot of loitering to get a shot that was free of people using the bridge for walking rather than ogling.

See? Span!It was designed by a former assistant of Isambard Kingdom Brunel, and it shows.

Iron works - as it always doesThe bridge was built between 1887 and 1889 for the London and South Western Railway, and got sympathetically refurbished just over 100 years later. It’s still in pretty good condition, and bears the twin reassurances of intelligent craftmanship and tasteful embellishment.

By defying logic and allowing your brain to process information from an illogical point of view, i.e. suspended above water, bridges inevitably alter your mood. A bridge that doesn’t entertain a continual procession of traffic, with unending, uncompromising noise, leavens this process with beauty.

In a location like this particular Thames crossing, in the silences between the romantic roar of passing trains, notions percolate, fancies take hold and ideas take flight.

Like how the river commands a pace of life unlike anywhere else in London. Like how it has become inseparable from people’s internal imprint of the Underground.

And like how it’s fun to have carriages pass alongside you above eye level: a hedgehog’s view of a train, only safer.
