Why are US railways not electrified?

The US railway system is partially electrified, but a large portion of it still relies on diesel locomotives. There are several reasons for this, including the cost of electrification, the availability of other sources of energy (such as diesel fuel), and the lack of a unified national rail system in the US.

While the US was a passenger train pioneer in the 19th century, after WWII, railways began to decline. The auto industry was booming, and Americans bought cars and houses in suburbs without rail connections. Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail.

Property rights. One of the most expensive parts of building new rail lines these days is securing land along a relatively straight path (you can't run trains at high speeds along too sharp a curve). The U.S. has strong property rights which makes securing land exceedingly expensive.

American railways were also built on a wider gauge (the distance between the rails), which allows for larger and heavier trains. As a result, American freight railways are much more efficient than their European counterparts, carrying almost three times as much cargo per mile of track.

In fact, the percentage of electrified rail is not even 1%, but the only source I had indicated that it was under 1%, so I rounded up. Meanwhile, India is at 83% rail electrification, and is ahead of schedule to achieve almost 100% grid-tied electrification.

Why don't we have driverless trains in UK? As I made clear to the Assembly last year, the London Underground system is an extremely complex environment, in particular, the deep tube lines. For reasons of safety, they are not suitable for driverless trains and there are no plans for their introduction.

As a result, electrified rail is currently used on less than 1 percent of U.S. railroad tracks while electricity supplies more than one-third of the energy that powers trains globally.

Only a measly 375 miles of U.S. track are equipped for 100+ mph speeds. U.S. rail tracks are typically too old to handle the speed of new train technology. The limits of the rails can reduce the effectiveness of the train speeds, sometimes by more than 100 mph.

Not all train tracks in the UK are electrified and, further, there are two main systems of electrification, overhead and track-based. The latter can be further split into two; three and four rail electrification.

Train tracks in UK are electrified so that they can provide power to the electric locomotive our the electric traction motors of the train.

Train tracks are private property. Walking, biking, jogging and standing on or next to them is considered trespassing. With court and penalty assessments, a first-time offender may have to pay nearly $400. You Might Not Hear the Train Coming.

Electric trains alleviate the need to use land for roads and highways and improve air quality by reducing fossil fuel combustion.

Train Design Due to their opposing priorities, American and European trains are designed quite differently. American trains are typically longer and wider to accommodate more freight, while European trains are shorter and narrower to allow for more nimble movements and quicker acceleration.

As far as I'm aware, there's no legal limit. Passenger trains do not normally exceed 12 cars (around 900 feet, dependent on rolling stock type), but many are much shorter than this.

Why are trains in America so slow? Because most tracks are optimized for heavy fright trains which in America are more important, economically, than passenger transportation. Heavy trains displace tracks, sleepers and ballast so that it is impossible to let locomotives and passenger wagons run with higher speeds.
