The major junction on the CSX Detroit sub is known as Delray. At this point south of Rougemere the CSX joins the Norfolk Southern on jointly owned double track which ends on the Detroit terminal yard at the rivers edge. At Delray this double track crosses the Conrail line leading to the Detroit river tunnel. Grand Trunk North/South traffic also passes through the junction on CR /NS trackage rights.  Most traffic into Detroit on any Class 1 Railroad will pass through the CSX controlled interlocking at Delray.

Viewed from the North, the CSX/NS double track is in the foreground.
