The distance from the Philly Amtrak Station to the Crash Junction can be measured from aerial/satellite pics. The time has been stated as about 11 min after leaving the station. NTSB have indicated that speed was 70 mph (after acceleration to same) and gave some speed vs time numbers for the last couple of minutes. It would be good to know the exact location the other train was hit as it apparently was using the same right of way. I also noted that the NTSB spokes person also gave 910 as the departure time from Philly.
