I sat in the bar on the mezzanine level, looking down at the jostling throng. There were crowds of people, rivers of humanity, rushing streams and babbling brooks of concerns: work, life, holiday, family, health. The people flowed back and forth across the concourse, each intent on their own business.

And it seemed to me as I sat in the bar, nursing my beer, that amongst the swirling crowds, that sea of people, just a few of them stood out. Across space and time, I saw a handful of people crossing this station concourse.

A man – two men – in morning suits appeared as from the pages of history. It was 1957. Britain was only slowly recovering from the austerity of rationing. There was a greyness, a grim and drab feel to the station. These two young men were rushing, desperate to catch their train to Dorking. For it was a special day for them both. One was a Best Man; the other, the Groom. They had been in what seemed like an endless queue, and somehow, they had convinced the staff of the railway company to let them jump the queue and get on. Now, at least, they were almost on the platform and on their way.

I took a pull at my pint, and when I looked down again, the scene had changed. Soldiers streamed across the station. Orderly ranks, serried columns. Rifles, rucsacs, the harsh shouts of sergeants. These men were entraining for Dover, bound for Flanders field. The hopes and fears of a generation of young men are hidden on a thousand faces. Here is a young subaltern, pink of voice and cheek, bravely concealing his worry, doing his best, biting his lip. His men may have to depend on him being strong.

Back in the present, I see a young lady, a refugee from war, crossing the station carrying everything she owns in one immense suitcase. Three young children accompany her, silent, scared, intimidated by the noise and crowds. Their mother knows only a few words of the language; she holds little or no currency. But she and her kids are in a better place by far than where they were before. .

Here is a youth in his eary twenties, visiting the big city for the first time. perhaps. He’s crossed by tube from one of the great northern terminii, and must now make his way to a small town in Kent, for a job interview. Days before, a mighty storm leveled trees all aross the south of England. He will soon travel by bus through all that chaos of fallen branches and broken limbs, from a town whose very name has been rendered a lie by the storm.

The scene changes again and I see a man carrying a small grip crossing the station. The crowds have all disappeared and the grey light of early morning can be seen in the glass roof. He has come up from the underground to find it pouring with rain. He pauses for a moment to take in the scene. Rain cascades from the gutters. The tarmac gleams wet in the reflected street lights. He crosses the forecourt, taking in the calm of early morning. The rain, the sound of the rain, calming his nerves, as he makes his way to the airport train and the other side of the world.
