The problem is they've torn up so many existing lines because they weren't needed at one point, now they're needed and they don't want to lay the track for it.
The problem isn't that they don't want to lay the tracks, the problem is the economics. Today it costs $US1-2 million dollars to lay one mile of track. It takes one hell of a return of investment to get that money back after fixed expenses like employees, maintenance of rolling stock and right of way, financial obligations, etc. When the majority of railroads were built shortly after the Civil War, they relied on plentiful cheap immigrant labor for track laying work. Back then unions didn't exist, there was no such thing as minimum wage or income tax, and cost of living was very low. After WWI, few new railroad grades were built.
The merger fever starting in the 1960s saw much redundant trackage eliminated in the last sixty years. But they were intentionally picked clean to eliminate competition, knowing full well that cost to restore trackage would be a detriment. The abandoned right-of-ways and structures were also a property tax obligation that they wanted to unload quickly. Former good grades that were excellent routes were decimated wherever possible - many became farmlands, targets of urban development, and highway grades.
I would gladly pay more for a bundle that did not include ESPN, or any of the other "sports" networks, or Empty-V or any of its myriad clones. Or the shopping channels.
I cut the cord since 2000 waiting for ala carte. Until it is offered bundle-free, the cable companies are not getting another dime from me.
You are in the hall of the mountain king.
