Above, an old photograph of the Pere Marquette Plymouth Yard taken in 1913.   Below, modern day Plymouth:  Looking north on the CSX Saginaw Subdivision at Plymouth.  The green over red dwarf signal is for a northbound train which will proceed on the wye to Rougemere.  Beyond the wye is the home signal for the diamond.  Past the diamond is the yard and the yard office (former train order station) is on the left at the crossing of the CSX Plymouth subdivision.  April, 2002.  [Dale Berry photo]
