A signal failure at the busiest train station in the greater Paris region led to travel headaches for thousands of commuters in the French capital on Wednesday morning.
Gare Saint-Lazare, which normally sees nearly 450,000 passengers pass through it every day, came to a grinding halt on Wednesday morning as technicians did their best to fix the signal failure.
"This is a big glitch," a spokesman for France's national rail company SNCF told AFP. The technical teams have been hard at work since 2.30 am "to carry out the necessary checks and repairs".
SNCF has asked passengers of the L, J, Intercités and TER Normand lines to postpone their journeys.
Temporary stations have been created at La Défense, Houilles Carrieres-sur-Seine, La Garenne-Colombes and Argenteuil.
Customers planning to travel are advised to consult the SNCF mobile app and the Transilien.com website.
Naturally it didn't take people long to start responding to the chaos on Twitter.
One user tweeted: "'Postpone your journeys…' SNCF thinks that people who are at Gare Saint-Lazare at 8 am are going on a picnic, hiking or to the beach…"
"Reportez vos déplacements…"
La SNCF songe sans doute que les voyageurs qui sont à 8h00 à Saint Lazare partent en pique-nique, en randonnée ou à la plage… https://t.co/MIzFnACztY

And others captured the packed station on camera:
