In 1867, a depot was built one block east of the present location. The railroad at that time consisted of two tracks and passed through town on ground level (crossing the streets at grade). In the mid-1890s two more tracks were added to the line and most crossings were elevated and bridged, so the 1867 depot, was razed and replaced.
