#TheJourney: ITV News follows the constant flow of refugees to the Greece-Macedonia border

The huge numbers of refugees willing to spend weeks crossing land and sea to reach Europe are showing no sign of letting up.

This week ITV News is following the vast tide of people sweeping out of the Middle East and across Europe.

Correspondent Martin Geissler reports from Gevgelija on the Greece-Macedonia border, a crossing point where more than 10,000 refugees have passed in just 24 hours:

We rolled up to the Greek-Macedonian border just before nine in the morning. Already there was a queue of buses stretching as far as the eye could see.

There's a temptation in these circumstances to start filming at the beginning and work your way along the line, but it soon became clear that adopting that policy would take days.

We walked a mile or so to the front of the line. I counted eighty coaches parked up at the side of the road.

At 50 euros (£35) per ticket from Athens, these fifty- and eighty-seaters are doing a roaring trade.

Along the way we met a couple of familiar faces, we'd last seen them spilling off the boats in Lesbos just three days earlier. They move fast, these people.

Interestingly, we weren't allowed to cross the border with them. Soldiers monitor the movement, but it's an unofficial crossing point and Macedonia's not in the EU.

If you don't have any paperwork, they let you take this route, but if you do have a passport you have to go the long way round.

Across on the other side, tempers start to fray as the crowds try to bundle onto trains.

The Macedonian government has laid on the transport, at a price, which will sweep these people across this country and out the other side, a thousand at a time.

After that, they're somebody else's problem. And then the next lot arrive.

The people making this trip know that Europe can't handle them all. Tarik, an articulate, well educated man from Syria, told me he has sympathy with the countries where they'll eventually try to settle.

I couldn't help but sense the irony in this. A Syrian, fleeing from war, expressing concern for us.

The only way to stop this madness - and it is madness, let's be in no doubt about that - is to stop the war, he told me.

Sadly, that's easier said than done.

We watched as the train pulled off into the twilight, then hit to road ourselves. Next stop Serbia.

This morning it occurred to me that we can't keep up with these people.

They're moving faster than we are, travelling day and night if they can. They don't stop, and nor does the flow. It's constant. That's quite a thought.
