Railroad workers using blowtorches and cranes to remove the wreckage of two trains that collided in northwestern India found six more bodies under the debris Sunday, bringing the death toll to 46, a news agency said. Rescue workers continued to cut through the mangled remains of the coaches a day after the Amritsar-bound Howrah Mail Express collided with a freight train in dense fog at Sarai Banjara, a small town in the state of Punjab. Forty-six bodies had been found and taken to nearby hospitals, United News of India reported. Another 150 people were injured in the pre-dawn collision. The Howrah Mail Express had hit four cars that had uncoupled from the freight train and toppled onto its path on a parallel track at Sarai Banjara, about 150 miles north of New Delhi. India's railroad minister Mamata Banerjee, who visited the accident site early Sunday, ordered an investigation by a Supreme Court judge, Associated Press reports.
