Looking back at Lincoln: On April 25, 1865

The young Teddy Roosevelt and his brother Elliot watching the funeral procession from their grandfather's window.

On this day in 1865, Abraham Lincoln's coffin was placed on a 14-foot long funeral carriage drawn by 16 horses, and carried through the streets of New York City in a grand funeral procession.

This from a great website that documents the entire timeline of 'The Lincoln Express' and all of its stops between Washington and Springfield:

At about 2:00 P.M. Mr. Lincoln's coffin was placed on a magnificent 14-foot long funeral car. It was drawn by 16 horses wearing long blankets. A funeral procession began that went up Broadway to Fourteenth Street, over to Fifth Avenue, up Fifth to Thirty-fourth Street, and across Thirty-fourth to Ninth Avenue to the Hudson River Railway Depot. 75,000 ordinary citizens marched in the huge procession through New York's jam-packed streets. Windows along the route rented for up to $100 a person. When the procession neared Union Square, it passed Theodore Roosevelt's grandfather's home where the 6 1/2 year old future president was viewing the proceedings from a second story window. Shortly after 4:00 P.M. the funeral train was on its way again - this time headed for Albany (141 miles away). During this leg of the journey the train was pulled by a locomotive named the Union, and the pilot engine was named the Constitution. Large crowds of spectators gathered as the train passed through Manhattanville, Yonkers, Dobbs Ferry, Irvington, Tarrytown, Sing-Sing, Peekskill, Garrison's Landing (opposite West Point), Cold Spring, Fishkill, North Hamburg, Poughkeepsie, Hyde Park, Staatsburg, Rhinebeck, Barrytown, Tivoli, Germantown, Catskill, Hudson, Stockport, Coxsackie, Stuyvesant, Schodack, and Castleton. The train arrived in Albany at 11:00 P.M., and the coffin was moved to the State House for public viewing. Throughout the night the local citizenry passed by to pay their last respects to the slain president.
