The European Parliament says it's "ready to explore" the idea of giving 18-year-olds free interrail passes, possibly via a lottery.
It's claimed it would stop more nations leaving the EU by helping young people "experience what it means to be a European".
But MEPs say that actually doing it would "present many challenges".
The tickets, which let you ride trains in 30 different countries, normally cost between £150 and £360.

German MEP Manfred Weber thinks that younger generations need to act as a "counterweight" to the threats the EU is currently facing, describing how "the mobility of young people is essential in promoting a sense of belonging to Europe".
Eighteen-year-olds in a country not on the interrail network would get extra cash.
This would go towards paying for people to get a bus or a ferry to their nearest interrail station.
Weber reckons the scheme would also help reduce carbon emissions. And he thinks it will make people feel proud to be European.
He described the scheme as giving "every young person in Europe the same gift that [some] young people experienced over the summer with interrail.
"A gift of learning about the beauty of Europe, to experience neighbours from other countries as friends, and simply to experience what it means to be a European."
And this woman says she's going to look into the possibility of making it happen
"We admire the boldness and the level of ambition and we are ready to explore it further," says European Transport Commissioner Violeta Bulc.
She's promising the commission will explore ways of getting it funded.
"We will also examine how to ensure that it is truly accessible to all and is as inclusive as possible."
And what if it's just too expensive?
"An attractive option might be to have a lottery open to all or specific categories of young Europeans, with a significant number winning free tickets," Ms Bulc added.
She said if it's successful, the idea could be extended so it is "not only limited to rail tickets".
But everyone agrees that putting the idea into practice wouldn't be easy.
Other than the cost, there are also other barriers such as the capacity of the trains.
Will it apply to British 18-year-olds?
If it happens while Britain is still in the European Union, yes.
Theresa May has indicated that the Brexit process - Britain's exit from the EU following the referendum in June - will begin before the end of March 2017.
But it could be several years before the country's full departure actually happens.
Emma McClarkin, a Conservative MEP, told Newsbeat the interrail idea is a waste of time.
"Eighteen-year-olds don't need a rail ticket.
"They want real opportunities to fulfil their dreams like getting on the [housing] ladder, to get training for great jobs and fantastic careers."
