I read this for the first time after it had been "locked off" and wanted to add a comment. One has to keep in mind that much of the former B&O in Western Ohio and Indiana was built on swamp land and has numerous culverts & bridges over the various streams and ditches which were used to drain the swamp.

The CSX main traverses this area through Wood, Henry & Defiance Counties in Ohio (From Fostoria to Hicksville). Fortunately, when it was built the B&O had the foresight to elevate the roadbed above the surrounding land by approximately 6-8 feet.
In Eastern Indiana, there are several areas where the CSX main traverses through bogs. For example, the I-69 overpass over the CSX main between Garrett & Auburn faced major maintenance issues for several years, because the structure would settle due to the instability of the soil that it was built upon. Likewise, when CSX constructed the third main between Auburn Jct. and West Garrett they opened up at least one sinkhole that threatned the existing two mains which required several emergency ballast trains to dump into it to keep the existing track from falling into it. These bogs continue westward past Garrett to at least Kimmel or perhaps even Syracuse.
Another item to consider is that the existing trackage that was in place in Ohio & Indiana when CSX re-installed the double track was almost all using the Chessie era standard 122 lb. Rail. This rail has proven to be problematic for several reasons. 1. while it may have been sufficient to carry the tonnage when it was installed (and Chessie made it the 'system standard') in the 1970's it is no longer so. 2. 122 lb. rail is no longer mfg. by anyone so defects that are found have to be replaced by 'used' rail - because there is no new stock to be had. One would think that with the increased tonnage this line has seen in the last 10 years, there would be a rash of derailments on this 'tired' 122 lb rail trackage but (fortunately) it has not happened. (My brother is a track inspector for CSX with territory between Fostoria & Defiance Ohio and he pointed out the issues with the rail to me)
