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 locomotives usually cost 20% less than diesel locomotives, their maintenance costs are 25-35% lower, and cost up to 50% less to run. The chief disadvantage of electrification is the high cost for infrastructure: overhead lines or third rail, substations, and control systems.
Every battery locomotive that replaces a diesel will reduce carbon dioxide emissions by 3,000 tons per year, Wabtec estimates. But it is unlikely they can quickly replace diesel-powered trains.
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.
Electric Trains vs.Diesel-powered trains transfer about 30-35 percent of the energy generated by combustion to the wheels, while supplying electricity directly from an overhead powerline transfers about 95 percent of the energy to the wheels.
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.
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.
Today's train locomotives are already quite fuel efficient, especially compared to trucks. In fact, trains can haul one ton of goods an average of more than 480 miles on just a single gallon of fuel, making them 3-4 times more fuel efficient than trucks.
Railway electrification stands at about 37 percent of the global track length in 2018 (based on International Railway Union [UIC][1] data); this percentage has been growing over the last two decades by amounts that vary widely from year to year.
What are some reasons why trains are not fully electric? Batteries do not have the energy density needed. Charging would take a long time and require a huge charger that does not exist. Up front cost would be too large.
At age 62, I could push a train car down a track. Unlike a steam engine that would hammer the rails (a main reason why they were retired), modern railcars glide with low friction, and crushed rock underneath the tracks helps diminish impact. You won't hear it or feel it, Rangel says.
The intensity of sound will vary at night, sometimes louder and sometimes softer. It has to do with the height and strength of a temperature inversion just above the ground. On clear, calm nights, it is cooler at the ground than higher up.
Most countries have a freight decarbonization goal. These typically include shifting from road to rail and also electrifying rail (IEA, 2019; OECD/ITF, 2021). This model shows that the rail freight industry could expect to see a positive net present value and emissions reductions globally through electrification.
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.
