MADRID (AP) 鈥 The blackout that paralyzed the Iberian Peninsula for most of Monday had an especially fierce impact on high-speed trains that run across Spain.

Here are accounts from three affected passengers:

Trapped in a tunnel

脕lvaro Agust铆n had spent the weekend in Gij贸n, his hometown, and was traveling back to Valencia, where he works as a doctor.

Sometime after departing the northern Spanish city, his train entered a tunnel 鈥 and came to a halt. Agust铆n, 26, assumed it would be a brief delay, as is sometimes the case on this six-hour journey he knows well. He waited, then waited more. Two hours passed without any news.

Finally, train staff informed passengers of a power supply problem and said they didn't know when it would be resolved. An hour later, an emergency unit of soldiers arrived to distribute water and share the news of a blackout across Spain and Portugal. They, too, said they had no idea when power would be restored.

Eventually, the bathroom's toilet clogged, its odor seeping out into the car and forcing passengers to hold their shirts over their noses. Then the train鈥檚 emergency batteries ran out, plunging Agust铆n's car into darkness. There wasn't even the light from cell phone screens, as people sought to conserve their precious power.

鈥淥utside, even though they didn鈥檛 have internet, they were in the sun, while we were in the dark without knowing what was happening,鈥 Agust铆n said on Tuesday, after returning home to Gij贸n in the early hours of the morning.

Most passengers remained calm. Some even laughed and started singing to pass the time. But a 15-year-old girl in his car began suffering an anxiety attack. Agust铆n removed his stethoscope to examine her. Then he talked to her, giving her advice to help her control her breathing and calmed her down.

Nine hours after Agust铆n's train stopped, an auxiliary locomotive arrived to passengers' rescue, and took them to the nearest city.

Waiting in Barcelona

When Paquita Gonz谩lez, 53, arrived Monday at Barcelona's main train station, service had already been suspended. Hoping the disruption would be brief, she stayed put, expecting to catch another train to her home in Cadiz, in the south of the country.

Hours later, and nothing had changed. Gonz谩lez lay on the terminal's floor through the night, but was too stressed and nervous to doze off.

鈥淭he night was very hard, I鈥檓 old,鈥 she said the next morning. 鈥淭here were small children, all trying to sleep on the bare floor.鈥

As of noon on Tuesday, she was exhausted and still waiting for a spot on a train 鈥 alongside hundreds of other frustrated travelers trying to reach their destinations.

鈥淎nother day waiting,鈥 Gonz谩lez said through a rush of tears. 鈥淚鈥檝e been here for more than 15 hours.鈥

Card games and solidarity

Erika S谩nchez was on her way to Madrid on a high-speed train from Barcelona when her partner messaged her around 12:30 p.m. about 鈥渟omething strange鈥 at work: colleagues all over Spain were losing power.

Shortly afterwards, her train stopped 鈥渋n the middle of nowhere鈥 鈥 forest all around, but no town in sight, she said.

The conductor announced that he would open the doors to let air circulate and that he was going to conserve battery power by turning off the train.

Several hours went by. S谩nchez played cards with her seat neighbors and chatted with elderly women, who said the situation reminded them of the difficult times they endured in their youth. Others shared power banks and what little food they had around with the group.

鈥淭he people working on the train did a pretty good job and tried to distribute food and water to everyone,鈥 she added.

Six hours later, the train began moving and the passengers cheered. They arrived at a station in Guadalajara, 70 kilometers (44 miles) south of Madrid, where another train had also been diverted. Inside a nearby gymnasium, volunteers provided food for some of the 800 passengers, many of whom prepared to spend the night on the floor.

S谩nchez prepared to do the same, until a young woman offered to drive her to Madrid. At 3 a.m., she arrived home, 12 hours later than anticipated.
