This is why you shouldn't bring World War II relics to a train station

A passenger packing a World War II souvenir caused major delays on Eurostar trains in Paris on Monday, because actually, no, it's not a great idea to travel with a replica bomb.

Frustrated passengers tweeted about delays and posted photos of long lines inside the Gare du Nord station.

A Eurostar spokesperson said the delays were due to “some memorabilia which had been brought back from the war sites in Northern France,” according to Huffington Post UK. “There are lots of signs at check-in where we ask passengers not to do this.”

This is not the first time this has happened at the station — it's the seventh since 2011, according to the Evening Standard.

“On this occasion someone had done so without declaring it to customs, so there was an evacuation whilst this was checked,” the spokesperson said. “The object was found when all bags were scanned, as part of the regular check-in procedure.”

Some passengers who were delayed for hours considered themselves fortunate. In addition to the delays due to the security scare, there was also maintenance work that canceled the last two trains of the night.

“We were among the lucky ones as I believe a lot of others were stranded in Paris overnight,” passenger David MacLean, whose train left two hours late, told the Daily Mail.

The chaos is likely to precede more chaos, as French labor unions are planning strikes that will affect almost all modes of transit, from planes to trains to ports.

Those traveling around or through France should check on the status of their transit plans, and be prepared for delays.
