Take a look at the work of the Train of Hope, an organisation of volunteers helping asylum seekers in Vienna with food, clothing and medical supplies.
The volunteers prepare food for thousands of people every day, made from donated ingredients. They say they are keeping up with demand by reaching out on social media with the lists of items they need.
While the focus of the migrant crisis may be on Germany, Austria has also been inundated with asylum seekers with 15,000 crossing the border in just a single weekend in September.
By the time they reach Vienna, some families have been split up, forced to take different coaches at the border or separated on the train.
"We had one boy, who was missing, where his parents were already in Austria and the little boy was still in Malta," volunteer Benjamin Fritz said.
The volunteers try to help to reconnect people who have been lost on the way by reaching contacts in other cities and circulating photos on social media.
The United Nations' refugee agency, UNHCR, estimates that 18 per cent of asylum seekers crossing the Mediterranean to Europe are children.
Professional carers volunteer with Train of Hope, playing with the children in a makeshift playground.
The playground includes donated toys and spaces for the children to sleep.
The medical station is staffed by qualified volunteers and stocked with donated supplies, including an ultrasound machine.
The social media team works to put out calls for donations and help on Facebook and Twitter.
They also post pictures of missing family members in the hope of tracking them down.
The volunteers have set up a computer station so that people can contact their families to let them know they have arrived safely.
