STRASBOURG, France - European Union lawmakers travelling on a special train from Brussels to the French city of Strasbourg on Monday got an unexpected view of Big Thunder Mountain when they were sent to Disneyland Paris instead.

The surprise arrival outside the theme park elicited much mirth from the hundreds of MEPs (members of the European Parliament) and aides on board, who each month or so have to make the train trip.

That is because EU law sets Strasbourg as the official seat of the European Parliament even though much parliamentary business is carried out in Brussels.

"'Where magic comes to life' -- will Disney's slogan soon be that of the European Parliament?" tweeted one parliamentary press officer, Emmanuel Foulon, who found himself on the train at the Marne-la-Vallee-Chessy station near the park outside the French capital.

"A Mickey Mouse parliament?" asked the online news website Politico.

Others tweeted that the mistake highlighted the need for EU lawmakers to just stay in Brussels and stop the regular train journeys, which take nearly four hours, for their monthly four-day plenary sessions in Strasbourg, located in eastern France near the border with Germany.

"Could a new Disneyland be a suitable use for the Strasbourg buildings?" asked Pelle Geertsen, press aide to a Danish MEP, musing on what could happen to them if the European Parliament permanently settled in Brussels.

"And will this inspire a Disney movie?" he asked, suggesting a story about the parliament and a train "that wanted to go on holiday".

The Disneyland Paris stopover was, unfortunately, too short for the MEPs to disembark and indulge in some of the park's rides.

French railway company SNCF told AFP the train was delayed by 45 minutes because a track signalling error made it miss an interconnecting line it was meant to take as it approached the greater Paris region.

It was eventually shunted back onto the correct high-speed track for Strasbourg.
