Hungary has blocked the main crossing point from Serbia used by migrants as Austria, Slovakia and the Netherlands imposed border controls today.
Police closed a gap in the razor-wire barrier along the Hungary-Serbia border as other officers formed a human shield to block off railway tracks.
The move comes after it emerged that Hungary was bracing itself for a massive surge of up to 30,000 migrants in just one day.
It comes as Serbia attempts a huge 'push through' before its neighbour introduces tough new border rules.
A record 5,809 migrants entered Hungary in a new surge on Sunday, smashing the previous day's record of 4,330, Hungarian police have revealed.
The sharp increase came ahead of laws coming into force tomorrow under which people entering the EU country illegally can be jailed.
Index.hu reported that Hungary's neighbour Serbia would try to 'push through' as many as 30,000 migrants on Monday before the new Hungarian laws come in to force.
Hungarian official sources are quoted as saying Serbia would speed up the provision of buses for the migrants, who enter Serbia from Macedonia after leaving Greece.
Meanwhile, European Union members are on collision course today over proposals to distribute asylum-seekers across the continent - a plan backed by safe-haven Germany but resisted by several states in the east.
Once in Hungary, most migrants seek to travel onto western Europe, particularly to Germany and Sweden, via Austria.
But with tens of thousands crossing its frontiers, German authorities on Sunday decided to reinstate border controls, and all trains between Austria and Germany were temporarily suspended, leaving thousands effectively stranded in Austria.
In addition to the new laws, Hungary is also building a controversial 13ft fence all along its 110-mile border with Serbia.
This morning, Germany's Vice Chancellor Sigmar Gabriel said the country may take in one million refugees this year, up from the record 800,000 arrivals predicted so far.
'There are many signs that Germany this year will take in not 800,000 refugees, as forecast by the interior ministry, but one million, he wrote to members of his centre-left Social Democratic party.
It comes amid fears thousands of refugees will be plunged into 'legal limbo' as EU countries impose differing border rules to deal with the migrant crisis.
The United Nations agency UNHCR warned the European Union that it must avoid fragmenting into a patchwork of countries with different border restrictions.
A motorway linking Austria to Hungary, which crosses the border at the point where thousands of migrants have been streaming west towards Germany, has been closed in both directions this morning.
'The reason is the flow of migrants expected by the police,' the Austrian road operator ASFINAG said in a statement, adding that traffic in the other direction had been halted on the Hungarian side. How long the closure would last was unknown, it added.
The interior minister of the southern German state of Bavaria said on Monday that temporary border controls could remain in place 'for weeks at least' as the country grapples with an unprecedented influx of refugees.
Europe's largest and richest economy has been a magnet for many people fleeing war and poverty in Syria and other parts of the Middle East and Africa, with most crossing the border from Austria into Bavaria.
EU BACKS PLANS TO BLOW UP BOATS BELONGING TO PEOPLE SMUGGLERS OPERATING IN THE MEDITERRANEAN
EU member states approved on Monday plans for military action against people smugglers in the Mediterranean, seizing and destroying boats to break up networks operating out of Libya, sources said.
The European Union launched a first, intelligence gathering phase of its EU NavFor Med operation in July but now it will be allowed to stop and if necessary destroy boats which have carried thousands of migrants risking their lives to get to Europe.
'The conditions have been met' to launch the new military phase, one European diplomat told AFP.
The decision comes as EU interior ministers meet later Monday in Brussels to try and agree quotas for the redistribution of the massive flood of migrants fleeing war and upheaval across the Middle East and North Africa.
Many member states were reluctant to step up action against the traffickers for fear of getting embroiled in Libya where rival factions have been fighting it out for control since the ouster of longtime strongman Moamer Kadhafi in 2011.
EU leaders agreed however that there had to be a much tougher response, including the use of force, after more than 700 migrants drowned off southern Italy in April.
EU member states approved on Monday plans for military action against people smugglers in the Mediterranean, seizing and destroying boats to break up networks operating out of Libya
The second phase of the operation approved Monday still restricts EU NavFor Med to action in international waters.
A third phase involves military action against people smugglers inside Libyan territorial waters, aiming to destroy their boats and networks before they set sail.
This step is more controversial given the increased risks and requires at a minimum a UN Security Council resolution and preferably Libyan government agreement.
EU NavFor Med currently comprises four ships - one Italian, one British and two German - and sources said it will likely need several more vessels for the enlarged mission which is expected to begin next month.
The EU, which has no central armed force of its own, has taken part in a whole series of peacekeeping and civilian emergency missions, among them anti-piracy operations off the Horn of Africa, military training in Somalia and Mali.
With thousands of refugees arriving each day, Germany said it was reaching its limits and decided to temporarily introduce border controls late on Sunday afternoon, in a bid to stem the flood of arrivals.
'We need to have a stricter control here in general, because we have established in the past few days that there are many en route here that are not really refugees,' Bavarian Interior Minister Joachim Herrmann told radio station Bayern 2.
'It's got about in the last few days that you are successful if everyone claims to be Syrian,' he added.
Controls on Germany's border with Austria have led to traffic jams at crossings this morning.
Authorities in Bavaria said there was a roughly two-mile tailback Monday on the A8 highway at Bad Reichenhall, near the Austrian city of Salzburg, news agency dpa reported. Regional broadcaster Bayerischer Rundfunk reported a four-mile queue on the A3 highway near Passau.
A spokesman for German police on the border with Austria said they had arrested around 30 smugglers and about 90 migrants since the controls had been introduced.
Meanwhile, train lines between Austria and Germany reopened on Monday morning apart from one line to Munich, which was still closed because of people on the track, a spokeswoman for Austrian rail company OeBB said.
Luxembourg Foreign Minister Jean Asselborn told German radio that he understood Germany's decision, but said it was important that it remained a temporary measure.
'We need to all mind out that this doesn't result in a domino effect and that Schengen really collapses,' he said, referring to Europe's system of open borders.
He called on interior ministers from the EU's 28 member states who are meeting in Brussels on Monday to reach concrete decisions on how to redistribute about 160,000 asylum seekers across the bloc.
Not everyone in Germany believed the move to close the borders would improve the situation on the ground.
'These measures will not create more order but only much more chaos and will ensure that the conditions for the people now sitting or standing on the other side of the border will get even worse,' the parliamentary leader of the opposition Greens, Katrin Goering-Eckhardt told rbb radio.
It comes as France called for the 'scrupulous respect by all European Union countries' of rules setting out the bloc's borderless Schengen zone.
'These rules, in particular, require the registration of migrants in the country where they crossed the (EU's) external borders,' French Interior Minister Bernard Cazeneuve said in a statement after speaking with his German counterpart.
Germany made the decision to reimpose border controls after admitting it could no longer cope with a record influx of refugees. The city of Munich alone recorded an influx of 63,000 asylum seekers in two weeks.
Under the Schengen agreement, temporary border controls are allowed for reasons of 'public policy or internal security'.
France's anti-EU, far-right National Front on Sunday party urged France's leaders to 'suspend urgently the Schengen agreement and re-establish its borders, especially with Germany.'
Interior ministers from EU nations will meet this afternoon in an emergency council called to deal with the unprecedented influx of migrants.
Diplomats said after talks in Brussels on Sunday that Hungary, Slovakia and the Czech Republic were refusing to accept the compulsory distribution of 120,000 asylum seekers - even though Hungary, which has taken in large numbers, would benefit.
Renewed discussions on Monday morning did not produce any breakthrough either. One diplomat said Lithuania and Romania had also expressed unhappiness with the scheme that would oblige them to take in thousands of migrants fleeing violence and oppression in Iraq, Syria or Eritrea.
'I don't have the idea that we will get agreement at ministerial level,' the diplomat said, adding that meeting may just result in vague words on future relocation of migrants.
'The biggest question will be if there will be a wording on quota system and how it will look like,' said another.
European Council President Donald Tusk said on Friday he would summon EU leaders for an emergency summit if their ministers could not agree a solution. However, some governments question the value of such a meeting before interior ministers meet again for a regular council on Oct. 8.
Among arguments EU and German officials have used to press eastern leaders who say their societies cannot take in large numbers of immigrants have been warnings that failure to fix a common plan on migration could wreck the Schengen open borders system which is especially valued in formerly communist states.
Home affairs ministers will first receive a briefing by a number of EU and United Nations bodies, such as EU border agency Frontex and refugee agency UNHCR, about the latest information on migratory flows.
They will also hear a presentation by the European Commission on its new proposals to redistribute asylum seekers across the bloc.
An earlier plan to relocate 40,000 from Italy and Greece is expected to be given a legal green light by ministers, partly because it is voluntary - a result of EU leaders blocking a Juncker proposal for mandatory quotas in June.
Diplomats said that Hungarian objections to the separate Juncker plan to relocate 120,000 from Italy, Greece and Hungary meant that the wording of the proposal would no longer specify from which countries asylum-seekers would be moved.
Talks among EU envoys had also led to tougher wording on plans to deport unwanted migrants and tighten defences of the bloc's external borders - demands especially of eastern states.
