Amtrak AEM-7 No. 941 leads a Harrisburg, PA bound "Keystone" west along Northeast Corridor passing the tower at Princeton, NJ. The track to the far left is for the "Princeton Dinky" - a short commuter train that makes the hop into Princeton proper, and Princeton University. This scene has changed over the last few years with upgrades made to the catenary for speeds of 160 mph in the "future", up from 135 mph.
