Each railroad has its own style of mile post and its own way of numbering mile posts. Several railroads use their mile posts to measure every main and branch line from one zero location. The Pennsylvania Railroad used a cast metal mile post, with a sloped top facing the track, and sides angled so the cast number on each side would be visible from both directions. For the Southern Pacific, mile post zero is San Francisco, 3rd and Townsend Streets. In the case of the Seaboard Air Line, zero is Richmond, Virginia. The Lehigh Valley (LV) mile posts start at the ferry slip on the New York side of the Hudson River, across from their Jersey City terminal station. The New York Central mile posts were stone or concrete, in the shape of a headstone.
