[Q]: BOSTON, Massachusetts (CNN)  -- The operator of a trolley that rear-ended another trolley should have been able to see the other vehicle was stopped 480 feet ahead, a federal investigator said Monday. Passengers walk past firefighters at a Green Line station in Boston after the trolley collision Friday evening. The trolley driver has told investigators he was text messaging during Friday night's collision, which injured 20 people. The Massachusetts Bay Transportation Authority, which previously had banned operators from using cell phones and other portable devices, now has told employees to leave the devices at home while on duty, National Transportation Safety Board member Debbie Hersman said Monday. Hersman also noted investigators have determined that the operator may have missed some crucial indications of a stopped trolley ahead on the tracks.  Watch new transit rule on cell phones » . "There were several signals -- two green signals, a yellow signal and a red signal -- coming out of the station, and the point of collision occurred 80 feet past that red signal," Hersman said. "We did a site-distance test, and we know that the operator had the ability to see the trolley stopped in front of him 480 feet in advance of the collision." Boston officials said over the weekend that the trolley operator was using his cell phone. Numerous media outlets, including CNN's Boston affiliates, have identified the driver as 24-year-old Aiden Quinn. "The operator of the striking train was interviewed at the hospital by two detectives," said MBTA general manager Daniel Grabauskas. "He admitted that he was texting at the time of the accident." The operator told detectives that, when he looked up, "it was too late as he applied the brake and the train struck the other trolley," Grabauskas said. He described himself as "outraged." "We have reinforced for a number of years that the use of cell phones or any other kinds of electronic devices while operating a train or a bus is absolutely prohibited," Grabauskas said. Though the investigation is ongoing, he said, the two-year employee will be fired if his version of events is confirmed. None of the injuries was considered life-threatening, the MBTA said. The collision happened at 7:18 p.m. ET Friday as the Green Line trains were traveling between the Park Street and Government Center stations in downtown Boston. Both trains were traveling westbound when one train rear-ended the second, an MBTA official said. A train operator also was text messaging last year in a California train crash that killed 25 people. CNN's Rob Frehse and Gary Bender contributed to this report.

[Q]: (CNN) -- A competitor has died and another is in hospital following a tragic end to the World Sauna Championships in southern Finland. Russian Vladimir Ladyzhenskiy died Saturday after taking part in the final of a competition in which contestants are required to withstand rising temperatures for as long as possible. Finnish finalist Timo Kaukonen was also taken to hospital for treatment, organizer Ossi Arvela said in a statement posted on the event's website. Images of the contest showed Ladyzhenskiy and Kaukonen sitting side by side in the sauna. Both contestants can then be seen lying on the ground, apparently doused in water. Ladyzhenskiy appears to be suffering from severe skin burns. "The event was interrupted immediately after the accident. Competition organization grieves these sad events," Avela said. Finnish police and organizers are investigating the incident, Arvela said. But he said first aid personnel had been in place and all competitors taking part in the contest had provided doctor's certificates. "All the rules were followed," he said. The World Sauna Championships take place annually in the town of Heinola.

[Q]: (CNN) -- The 54 men and 14 boys rescued after being found chained this week at an Islamic religious school in Pakistan have been reunited with their families or placed in shelters, authorities said. The group was discovered in an underground room with heavy chains linking them together. The school, Al-Arabiya Aloom Jamia Masjid Zikirya, which also was a drug rehab clinic, is in Sohrab Goth, a suburb of Gadap in Karachi. All 14 boys were returned to their families, senior police official Ahsanullah Marwat told CNN. Of the adults, 47 had been released to their families, and seven were handed over to a shelter for the homeless, he said. Three people who worked at the facility were arrested, but the four men who ran the place were still at large, Marwat said. Officials said the facility was part madrassa and part drug-rehab facility, and the captives were chained at night apparently to prevent their escape. "The operation was successful, and we plan on continuing our work to ensure that places like this are shut down," Marwat said. Many of the captives told police their families sent them there because they were recovering drug addicts. During the day, they worked and did religious studies. But the future of the rescued children was unclear. One woman told a local television station that she was willing to pay the police to keep her troublesome child. She said she would rather have the facility remain open, regardless of how it treated the children. Many others, however, said they were in shock and disbelief over the allegations. One man complained he was deep in debt after paying the school a large amount of money to board his son.
