How much does it cost to electrify a railway?

Moyer also countered that the $4.8 million per track mile figure is related to the most expensive areas to electrify a rail line, such as on an overpass. He estimates initial installation costs to be around $2 million per track mile and $2.5 million per doubletrack mile.

Even taking typical peaking demands into account, electric energy is typically less expensive than diesel fuel. The comparable cost for the 150-mph locomotive- hauled electric train was just $2.61 per train mile as compared to $6.10 for the diesel.

Very generally, rail infrastructure construction costs can range from $2 million per mile in flat rural areas to $300 million per mile or more in urban areas.

The Association of American Railroads claims 220000 km. Capital costs for electrifying something that large would be just a bit high, and with continuing subsidies for oil the cost savings simply aren't there. Additionally, the vast majority of the US rail network is privately owned and operated by dozens of railroads.

The Swiss rail network is the largest fully electrified network in the world and one of only eleven to achieve this. China has the 2nd largest electrified railway length with over 70% of the network, after India overtook china having almost 80% of its railway network electrified.

Some locomotives collect electricity from overhead cables, while others take power from a third “live” rail on the track. It is very expensive to build the lines or rails that carry the electric current, but electric locomotives are cleaner, quieter, faster, and more reliable than steam or diesel engines.

For intermodal, about 26-27 cars = 1 mile.

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.

The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.

Electric locomotives are typically 20% less expensive than diesel locomotives. Maintenance costs can be 25 to 35 percent lower and operating costs can be up to 50%.

Implementing high-speed rail will keep billions of dollars in the U.S. economy by decreasing the amount of oil that the U.S. consumes. According to the International Association of Railways (UIC), high-speed rail is eight times more energy efficient than airplanes and four times more efficient than automobile use.

The interstate highway system cost $129 billion — roughly $290 billion in current dollars — and took 35 years to complete, running from 1957 to 1992. The $1.2 trillion infrastructure bill enacted in 2021 has $102 billion for rail, but none of the money is set aside for high-speed rail.

MORE DETAILS

Disadvantages of electric traction include: high capital costs that may be uneconomic on lightly trafficked routes, a relative lack of flexibility (since electric trains need third rails or overhead wires), and a vulnerability to power interruptions.

MORE DETAILS

No, trains have no gears, since these are unfeasible. That's why their fuel (if any) is converted to electric energy and then used to run motors.
