 WASHINGTON – As part of its ongoing investigation into the May 12, 2015, derailment of Amtrak Train 188 in Philadelphia, the NTSB today provides this update on the analysis of the engineer’s cell phone and related records. 
 
 The NTSB is conducting a detailed examination of the engineer’s cell phone calls, texts, data and cell phone tower transmission activity records from the phone carrier; and records from Amtrak’s on-board Wi-Fi system. 
 
 Analysis of the phone records does not indicate that any calls, texts, or data usage occurred during the time the engineer was operating the train. Amtrak’s records confirm that the engineer did not access the train’s Wi-Fi system while he was operating the locomotive. 
 
 To determine whether the phone was in “airplane mode” or was powered off, investigators in the NTSB laboratory in Washington have been examining the phone’s operating system, which contains more than 400,000 files of meta-data. Investigators are obtaining a phone identical to the engineer’s phone as an exemplar model and will be running tests to validate the data. 
 
 The engineer provided the NTSB with the passcode to the cell phone, which allowed investigators to access the data without having to go through the phone manufacturer. 
 
 Last year the NTSB lab processed about 80 personal electronic devices and more than 40 cell phones. The phone records analysis of the Amtrak 188 investigation has been more complicated than anticipated because the phone carrier has multiple systems that log different types of phone activity, some of which are based in different time zones. Investigators worked with the phone carrier to validate the timestamps in several sets of records with activity from multiple time zones to correlate them all to the time zone in which the accident occurred, Eastern Daylight Time.

 UPDATE: The NTSB determined the engineer wasn't using his phone or Wi-Fi at the time of the crash. 
 
 Investigators have determined whether the engineer in the deadly Amtrak crash that killed eight people and injured over 200 others in Philadelphia was using his cellphone, two sources told Reuters on Tuesday. 
 
 The National Transportation Safety Board is expected to release its latest findings on Wednesday between 9 a.m. and 10 a.m. The report says the officials wouldn't reveal their findings ahead of Wednesday's announcement. 
 
 Federal accident investigators have said Amtrak's train 188 was going 106 miles per hour just before it derailed on a curve with a 50 mph speed limit. Investigators said they were still analyzing cellphone records to determine whether engineer Brandon Bostian, 32, was using it while operating the train. 
 
 The NTSB reported last month Bostian's phone records show calls were made and text messages were sent the day of the crash but they were unable to determine at that point whether the phone was used while the train was in motion. 
 
 Bostian's lawyer, Robert Goggin, has said he kept his cellphone in a bag and used it only to call 911 afterward. Bostian, who was injured, told investigators he had no recollection of the crash, the NTSB said. 
 
 "The next thing he recalls is being thrown around, coming to, finding his bag, getting his cellphone and dialing 911," Goggin said the day after the crash. 
 
 Bostian, 32, had been an engineer on the Northeast Corridor for about three years. He was based in New York. He was specifically assigned to the Washington to New York route for several weeks before the derailment, the NTSB said. 
 
 He worked a five-day-a-week schedule — making a daily roundtrip from New York to Washington — and had a "very good working knowledge" of the territory and various speed restrictions, NTSB member Robert Sumwalt said. 
 
 Bostian spoke to investigators May 15, Sumwalt said, and did not report feeling fatigued or ill while operating the train. 
 

– The results of a "detailed and lengthy" probe into an Amtrak engineer's cellphone use on the day of the deadly derailment in Philadelphia hasn't turned up any shockers. An analysis of call data, texts, cell phone tower transmissions, and data relating to Amtrak's on-board WiFi system found no evidence that Brandon Bostian was using his phone while operating Amtrak Train 188 on May 12, the National Transportation Safety Board says in a press release on its findings.In addition, "Amtrak’s records confirm that the engineer did not access the train’s WiFi system while he was operating the locomotive." Bostian’s lawyer says his client kept his phone in a bag and only pulled it out to call 911 after the accident, per NBC Philadelphia. An investigation continues.
