At the time of Amtrak's founding, most of the freight roads had excess capacity. PRR and B&O still operated multiple-track mainlines controlled by lineside towers. In addition, they were usually the carrier of last resort, handling mostly low-valued, non-time-sensitive industrial commodities which moved in bulk.
All this began to change in the 1980's as a consequence of several factors: a stronger competitive stance due to deregulation, reduced expenses due to smaller crew sizes and longer crew districts, the growth of intermodal traffic as containerized imports boomed, and the first stirrings of the fuel crunch.
Most of those trends have continued to the present day, and I can add at least two more; a growing shortage of drivers willing to adjust to the traditional demands of the motor-carrier industry, and a public that could likely be enticed to force more freight traffic off the highways in order to free up fuel for automobile consumption.
At the same time, the freight roads strengthened their ability to directly monitor and intervene in the control of train movements. CSX dispatches its entire system from a single complex in Jacksonville. UP and BNSF follow a similar practice, with a couple of secondary centers in congested or growing areas. NS has a handful of offices and semi-local control is practiced in some areas where commuter traffic is a factor. The NEC is the only place where dispatching priorities are focused almost entirely on passenger moves.
Finally, several of the remaining high-capacity areas inherited from the freight roads were slimmed down to the bi-directional double track system first installed by NYC in upstate New York in the late 1950's. This method of operation works well, but only if everything moves at the same speed and there are no interruptions such as breakdowns, etc, and it is now the common practice on most main lines.
CSX was even more short-sighted, abandoning most of its former Seaboard Richmond-Jacksonville main in favor of the former Atlantic Coast Line which, while better-suited to passenger speeds due to superior grading and curvature, had already been reduced from double- to single-track in some areas.
The bill is about to come due; on top of all these trends, economic pressures are working toward putting much of the high-value manufactued/perishable traffic back on the rails it deserted in the 1960's.
Much of the needed capacity is there, in redundant, but not abandoned lines like the former Erie across the southern tier of New York State. But having endured misregulation for decades, the freight roads aren't enthused about allowing an uninformed public to start meddling again.
This issue is very broad in its scope, and it's linked to both the end of the Age of Petroleum and a likely financial crisis as the 1950's "beby boom" comes to grips with the realities of age and an underfunded retirement. Until a general study of the transportation/mobility crisis gains its rightful place as a cover story on the newsweekliles and a prime subject on the public-affairs brodcasts, it's going to continue to fester and grow.
