Gresch: What carbon balance? Fossil fuel is producing co2 faster than plants can absorb it, while plants are being replaced by urban sprawl and crops modified to produce more fruit and less oxygen-producing leaves. Most corn is being used to make co2 producing ethanol rather than food..Bruce4671: CSX (and Amtrak) may own their rolling stock, but the railroads own the track and an overwhelming percentage of the total rolling stock. They collect on the use of their rails regardless of condition (which is why there are so many derailments of both passenger and freight trains with tragic results), so they don’t bother with track maintenance – the engineer will be blamed anyway, just as airline pilots are, instead of airline maintenance or airliner manufacturers. I haven’t seen a gandy dancer in years.
