The Chief and the Super Chief carried thru sleeper's at different times, and from different roads....
In the East, the New York Central, Pennsylvania, and Baltimore and Ohio carried various thru sleepers with various 'western' roads.
I don't believe the Jersey Central ever participated in any of this. You need to peruse some old Official Railway Guides to fully research this, or maybe find some info here...
