Are electric trains feasible?

Today's rail networks largely consist of electric trains 'tethered' to electric overhead and live rail systems. However, this is not feasible everywhere due to the high infrastructure cost/mile, remote geographic locations, and the practicality of building through tunnels and bridges.

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.

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.

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.

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.

– What are the potential problems? OLE can suffer power supply failures or mechanical problems, such as the wires being displaced or damaged by objects, trains or bad weather. – What is the impact of this? If wires are displaced then no trains can run until the broken equipment is cleared.

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.

The United States, on the other hand, boasts only 806 miles of electrified rail lines — all of it confined to the Northeast Corridor and Pennsylvania's Keystone Corridor.

While full driverless autonomy is certainly technically possible, and is applied on various routes worldwide, it still accounts for only a tiny percentage of trains running today. New trains are still being designed and built with fully equipped driver cabins.

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.

Are trains becoming obsolete? No. Trains continue to be the cheapest form of long distance land transportation for freight there is. Ships and barges can carry more cargo for less, but they cannot transit the large land masses and certainly not as fast.
