A southbound Amtrak Regional Express races past a Bristol Township row of homes in Pennsylvania on an elevated fill.
This part of the line, like many built by the once mighty PRR, was elevated from the ground in 1930 in an effort to enhance speeds and safety. The original alignment went through the center of town further south (to the right) but was found to be too restrictive for the then-new high-speed GG1 electric locomotives due to a curve significantly sharper than the one that remains ahead of the train today. Amazingly, that ROW survives unknown to many as part of the Bristol Spurline Park Rail Trail.
