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

In comparison to the principal alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions, and lower operating costs. Electric locomotives are also usually quieter, more powerful, and more responsive and reliable than diesel.
Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line.
Electric trains are more quiet, and emit less sound than diesel engines. Electric locomotives don't have reciprocating parts so they are more easy to use on the track. They also require less maintenance.
Combustion engine tends to create more vibration, which translated to more sound. this will cause the wheel to vibrate with the track, which will cause more noise from wheel hitting the track by vibration of the engine. The electric trains don't have this issue.
Reliable – electric trains are between 40% and 300% more reliable than diesel trains. Longer And Faster Freight Trains - Electric freight trains are cheaper to operate, have more powerful electric locomotives which enables faster, longer, heavier trains with obvious commercial and network benefits.
Electric trains are superior to diesel trains for several reasons. They can accelerate and decelerate much more quickly, which reduces travel times between stations and allows more trains to be on the line at the same time. They are zero-emissions, so they're good for the climate and reduce local pollution.
Electric trains have always had no direct carbon emissions because they are run entirely by internal electric motors. However, the means of generating the electricity used to power these motors was predominately by burning fossil fuels or coal, both of which produce a large amount of carbon emissions.
Most freight trains in the US are already halfway to electrification. They deploy an electric drive that runs off a diesel generator. Diesel-electric locomotives first appeared in the 1920s and soon gained currency as a labor-saving, cost-cutting technology improvement over steam-driven trains.
Diesels can still operate on electrified lines, they simply do not pull power from the overhead wires, instead burning diesel to generate power. There are no clearance problems for diesels to operate on electrified lines.
Touching a third rail can result in electrocution, so usage of the metaphor in political situations relates to the risk of political suicide that a person would face by raising certain taboo subjects or having points of view that are either censored, shunned or considered highly controversial or offensive to advocate ...

There are a variety of disadvantages associated with electric traction. They include high construction costs that can cause difficulties to use in areas with low traffic and the inflexibility due to overhead and third rail wires required by electric trains. Also, they are vulnerable when power is cut off.
No.The speed difference between the fastest aircraft and the fastest trains is about an order of magnitude. The atmospheric density at ground level would generate too much drag for a train to go as fast as a typical jetliner, let alone go supersonic.
The train is operated by the French rail company SNCF for use on the LGV Est route, which runs between Paris, eastern France, and southern Germany. While in regular service, the train reaches a top speed of 200 mph.
