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.

– 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 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.

This solution replaces the use of diesel freight trains. Railways are efficient modes of transportation and a critical part of goods transport worldwide.
Electric trains are better for the environment than diesel trains, and they're quieter for both those on board the train and those living close to the railway.
