You could be fined $80 if you break this rule on nation's trains

Some of the most popular trains in the continent are cracking down on luggage.

The new rules are being introduced by French national rail operator SNCF.

If you're catching the train in France you'll need to be careful.

From September 15, you can only take three pieces of luggage each.

While this might sound generous, you might need to check your suitcase dimensions if you're planning to take a lot (or indeed, shop up a storm).

You're allowed two 'cabin bags' and a smaller hand luggage bag, such as a small backpack, The Sun reports.

Cabin bags must be no more than 50cm x 70cm x 90cm, while hand luggage cannot be more than 15cm x 30m x 40cm, as it has to fit under the train seats.

Meanwhile, as part of the rules, every item of luggage has to have its owner's name written or displayed, so inspectors can track down anyone who has broken the rules.

You could face a fine of $80 if you're caught out.

Meanwhile, if you're flying, be aware European airports have brought back liquid rules, after some did away with them.

It means all liquids, gels and aerosols in your hand luggage must be a maximum of 100ml.

They must be placed in a clear, resealable bag. The rules have been in place since 2006 after a foiled bomb plot.

Some airports were starting to ease the rules because of new scanners. But now the blanket ban has been brought back in.
