As investigators gather evidence about this week鈥檚 deadly crash of Train 188 along Amtrak鈥檚 Washington-to-New York run, new reports offer some tantalizing possibilities.

One is evidence that the engine鈥檚 windshield had been damaged before the derailment, perhaps distracting or injuring engineer Brendan Bostian. As he recovers from a concussive head injury, Mr. Bostian so far remembers little of what happened in the moments surrounding the accident, which killed eight people and injured more than 200 Tuesday night.

Another are reports that Bostian鈥檚 prior run that day had been required to travel at slow speed, putting him behind schedule, reducing the time for rest and preparation, and perhaps leaving him 鈥渇razzled,鈥� according to a longtime engineer who spoke to the Daily Beast.

Bostian鈥檚 earlier train experienced a 鈥渃ab signal failure鈥� after it departed New York for Washington Tuesday afternoon, which meant that Bostian could not rely on the electronic indicators and audible alerts in the cab and instead would have to observe, register, and interpret the signals 鈥� all of which relate to speed 鈥� with no backup.

鈥淚t鈥檚 absolutely crazy on the nerves,鈥� the longtime engineer said.

The New York Times reports that an individual identified as Bostian had participated in a discussion group on the聽Trainorders.com聽website, where he 鈥渃riticized a lack of safeguards to protect against human error, pointing out how fatigue, bad communication and 鈥榗utting corners鈥� could lead to accidents.鈥�

鈥淲hen others voiced skepticism of new safety technology, or dismissed the idea that an experienced engineer could make a simple mistake, the writer was often quick to comment to the contrary,鈥� the newspaper reported. 鈥淭he writer also said, 鈥業 wish the railroads had been more proactive in adopting鈥� safety technology.鈥�

The route of Bostian鈥檚 last run had been equipped with the Positive Train Control System (PTC), which can automatically slow or stop a train using Wi-Fi, GPS, transponders, and other well-known technologies. But it was still being tested before becoming fully operational.

Investigators with聽the聽National Transportation Safety Board (NTSB) have described Bostian as 鈥渆xtremely cooperative鈥� in the initial questioning. He voluntarily allowed a blood sample to be taken, indicating no presence of drugs, medicines, or alcohol, and he immediately turned over his cell phone, which had been switched off during the run.

At a briefing Friday, NTSB member Robert Sumwalt, who is heading the investigation, reported that one of the conductors on Train 188 heard a conversation between Bostian and the engineer on a Southeastern Pennsylvania Transportation Authority (SEPTA) train operating in the same area.

"She recalled that the SEPTA engineer had reported to the train dispatcher that he had either been hit by a rock or shot at, and the SEPTA engineer said that he had a broken windshield, and he placed his train into emergency stop," Sumwalt said. "She also believed that she heard [the Amtrak] engineer say something about his train being struck by something."

Trains being struck by thrown objects reportedly is a regular occurrence along the Northeast Corridor. The FBI is examining the windshield damage on Bostian鈥檚 train.

On Saturday, the Federal Railroad Administration (FRA) ordered Amtrak 鈥渢o immediately take several actions to improve safety along its Northeast Corridor.鈥�

This includes immediate implementation of Automatic Train Control (already in place for southbound trains) for northbound trains; analyzing the risks in all curves along the Northeast Corridor and implementing the appropriate technology 鈥渋mmediately鈥�; and increasing wayside signage alerting engineers and conductors of the maximum authorized speed throughout the corridor.

鈥淭hese are just initial steps, but we believe they will immediately improve safety for passengers on the Northeast Corridor,鈥澛燬arah Feinberg,聽the FRA鈥檚 acting administrator, said. 鈥淲hile full implementation of Positive Train Control is the most important step that must be taken to improve safety, it is not the only action that we will require of Amtrak and other railroads. As we learn more from the ongoing investigation of this derailment, we will take additional steps and enforcement actions as necessary.鈥�
