The Conrail Cyclopedia - Serving Conrail fans world-wide since 1998.

CR U23B Conrail inherited a total of 77 2,300hp U23B's from the Penn Central and 12 units from the Lehigh Valley (LV 501-512). Conrail assigned the PC locos to series CR 2700-2776, whereas the LV units became CR 2777-2788, respectively. They served a number of years but were retired by 1991.

These repaint rosters are my attempt to discover how long a predecessor ran in its original paint scheme and when Conrail painted it blue for the first time. All dates listed are the earliest and latest the unit was seen in that paint scheme. Dates often change as new photos are examined. If I know for certain that a date is the absolute earliest or latest, then I mention this in the notes. This is a constant work in progress aimed at helping those of us who model the transition era get our consists looking reasonably accurate for blue, stenciled, and original paint scheme ratios.
