PB&NE 206 was reengined with a 567CR block (R for counter-clockwise revolution) in 1955. The locomotive operated on both the Maryland & Pennsylvania Railroad (as #83) and Stewartstown Railroad (as #11). Since 2014, it has operated under its original #206 on the Allentown & Auburn Railroad in Kutztown, PA. While it now has an EMD 567C block, it retains its EMC electrical system and early lifting hood vents. Missouri Pacific #5 survives and operates as Thermal Belt Railway #1, repowered with a Cummins diesel. N series These locomotives were all nearly identical, except for cast versus welded underframes.
