Taiwan prosecutors probe train crash that killed 51

The train smashed into the construction truck that slid down a hillside above the tracks, the Taiwan Railway Administration said. Many passengers were crushed just before the train entered a tunnel, while some survivors were forced to climb out of windows and walk along the train's roof to safety.

The truck's emergency brake was not properly engaged, according to the government's disaster relief center.

The district prosecutor's office in eastern Hualien County, where the train derailed, confirmed it had interviewed the truck owner, among others, but was not ready to file charges.

Prosecutorial staff was visiting a mortuary on Saturday to examine the bodies, office spokeswoman Chou Fang-Yi said.

President Tsai Ing-wen was due to visit the site later on Saturday.

"We have asked the Transportation Safety Committee to conduct a strict investigation of the accident, and after fully clarifying the cause of the accident, we will explain it to everyone," Tsai told reporters on Friday.

We're asking passengers to forgive us for any delays, she said.

Meanwhile, workers have started removing some of the train cars.

"Repair work also has begun on the tracks including the tunnel where part of the eight-car train crashed. The operation should be done within a week," said Weng Hui-ping, head of the railway administration's newsgroup.

"During the repairs, all east coast trains will run on a track parallel to the one damaged in the accident, causing delays of 15 to 20 minutes," he said.

The National Fire Service confirmed the death toll which included the train's young, newly married driver and the assistant driver, and said over 100 people were injured. "Worst rail disaster in 73 years," said the government's disaster response center.

Train travel is popular during Taiwan's four-day Tomb Sweeping holiday when families often return to hometowns to pay respects at the gravesites of their elders.

Taiwan is a mountainous island, and most of its 24 million people live in the flatlands along the northern and western coasts that are home to most of the island's farmland, biggest cities, and high-tech industries.

The lightly populated east where the crash happened is popular with tourists, many of whom travel there by train to avoid mountain roads.
