Second pedestrian killed by Amtrak train in Maryland

A pedestrian was struck and killed by an Amtrak train headed to Boston Saturday, leading to regional service disruptions during a busy day for holiday travel, rail officials said. 

The incident took place at 4:34 p.m. north of Aberdeen, Md., an Amtrak representative said. The pedestrian, who was on the tracks as the train approached, was the only fatality. Three hundred passengers were on the train, many of them traveling home for the holidays. No injuries were reported. 

The train was stopped for two hours, officials said, before it began moving again. 

The incident is the second of its kind this week in Maryland.

On Tuesday, Kenneth Joseph Grabenstein, 55, of Delaware was killed by an Amtrak train in Middle River, The Baltimore Sun reported.

The train engineer told police Grabenstein was "standing in the middle of the tracks, facing the train as it approached," according to the newspaper. 

It is unclear why the pedestrian was on the tracks in Aberdeen.
