Sulfuric acid spills in leak from one car; NTSB, TSB of Canada investigating
This derailment explains the X900 series trains running on the CSX thru Fostoria. I have seen several X trains - including what appeared to be a CN 149 (3 CN motors) plus intermodals. The train moved from ex B&O to ex C&O via NE connecting track.
Generally there has been intermodals and a general freight moving thru the connection with symbols X901 thru X904.
