It seems then that all the vast armies that died during the war are escorting the phantom train of the President. The wind, if blowing, dies away at once, and all over the earth a solemn hush, almost stifling, prevails. If a train were passing, its noise would be drowned in silence and the phantom train would ride over it. Clocks and watches would always stop, and when looked at are found to be from five to eight minutes behind. Everywhere on the road, about the 27th of April, the time of watches and trains is found suddenly behind. This, said the leading watchman, was from the passage of the phantom train.
The route taken by Lincoln's funeral train, in large part, still exists -- marked by ancient railroad beds and towns. New Yorkers who commute daily from bedroom communities along the Hudson River, north of Manhattan, don't realize that they are traveling the same route as the 16th President's funeral train. So it is for thousands of unknowing railroad passengers.
