Was wondering if anyone is familiar with how empty hoppers where returned from points west and north of Conway (such as Ashtabula) to points on the Mon (Shire Oaks, Pitcairn, Ellsworth Br., Brownsville-MGA). A 1974 symbol book I have only lists an XEL running from Ashtabula to Ellsworth br (even though an earlier list shows XEL as Enola to Scully). Other wise there are many listings out of Enola (XEP, XEO, XEM) for Pitcairn, Shire Oaks and MGA. There is speculation that PC moved these in locals or as HOP-Xs. Anyone really know?
