Two CSX gems lie hidden in the Airport Industrial Park outside of Philadelphia. On the left is SD20-2 2402, still in YN1. On the right is B30-7 5552 in YN2. These have been here for a good five years or so now, and have not been moved since their arrival. Plans for them are unknown, but they are looking pretty rough, as the numberboards have been removed since the last time I saw them.
