Back to back is best. On Sunday, November 27, 2011, the main attraction on the "Sunday Day After Thanksgiving Day" was Amtrak extras using borrowed commuter equipment from other agencies. But keep the camera ready always, as there are always surprises. NJ Transit GP40PH-2s 4110 and 4112 (both ex-CNJ) are in excellent shape for a rare back to back photo under wire as they pass through the Metropark Station in Iselin, NJ.
