Funeral Trains (with photos):
The funeral procession made a statement about status. As years went by, the method of transportation to the cemetery changed, but it usually reflected the status of the deceased. One method before the motorized hearse became common by both the rich and ordinary families, the funeral operating on rails. These were used in conjunction with horse-drawn hearses.
Travel to outlying cemeteries via carriage roads were often poor, especially in bad weather. An easier method for people to reach those outlying cemeteries came in the form of funeral trains on both traditional railroad lines as well as electric rail.
Probably the most known funeral train was the procession taking President Abraham Lincoln's body from Washington, D.C. back to Springfield, Illinois for burial.
