China's CSR Corp, whose parent made the trains involved in a deadly crash last year, said Tuesday it had won 3.3 billion yuan ($524 million) in orders that include supplying the Beijing metro.

Among the four orders, the company will also supply carriages to Hong Kong's MTR, which operates the rapid transit railway in the former British colony, CSR said in a statement to the Hong Kong stock exchange.

The company is listed in both Hong Kong and Shanghai.

Other contracts include the sale of metro trains to the eastern city of Wuxi and an order for freight cars for a domestic port company, it said.

The parent of the company -- state-owned CSR Group -- made the bullet trains involved in a collision near China's eastern city of Wenzhou last July, which killed at least 40 people and injured hundreds.

China has built the world's largest high-speed rail system from scratch in less than a decade, but the ministry has been accused of overlooking safety in its rush to develop the country's vast transport network.

In the weeks following the accident, authorities announced a halt to new train projects and introduced new speed restrictions on bullet train lines.

An accident report released late last year blamed design flaws and poor management for the crash, which sparked public fury and worries over the safety of the nation's rail system.

The government said previously more than 50 people would be punished for the disaster.
