On the PTRA, unless the industry has contracted with us for track maintainance, our responsibility ends at either the industry side of the switch into th eplant, or 50" past that point…a lot depends on when the contract was performed.
And not to argue, but some of these plants have grow up and around tracks that have been there since 1924, in some instances, 1910.
Changing the alignment or curves is impossible, without rebuilding large parts of the plants.
Buried petroleum and natural gas pipelines, over head pipe bridges, even buildings would have to be moved.
Good luck getting any of these plants to shut down even a tiny corner of production for something like that.
In some instances you would be talking millions of dollars a day in loss production.
Examples are…

If you know what you are looking at, you can see why the track can’t be moved.
For those of you who have never been inside a refinery…this is the PTRA South Shore main through Lubrzoil on the left, and Shell Deer Park on the right.
All the little signs on both sides of the right of way are burried pipelines…intra plant feed stock lines, customer feed lines, full of natural gas, liqufied petroleum gas, and a bunch of really awful stuff I can’t spell!
When this track was first laid down, this was the front of the refinery, and oil came up Buffalo Bayou in open wooden barges…

Overhead pipe bridge inside Shell…no way to move that with out a major shut down.
