The Main Disadvantages Of Mine Electric Locomotives

Mine electric locomotive, also known as an electric train, refers to a train that obtains electricity from a power supply network (contact network) or a power rail, and then drives the vehicle with a motor.Let's introduce its main disadvantages.

1. The disadvantage of electric locomotive is that it does not have a power source itself. Electricity comes from external cables or electric rails. If a power failure occurs due to force majeure such as natural disasters or wars, it will not be able to operate, resulting in paralysis of transportation and even accidents. In 2008, a large area of heavy snow fell in South China, which damaged the power supply equipment along the railway. As a result, multiple trains of electric trains were suspended and serious passengers were stranded. Hybrid power is a compromise solution, that is, the electric locomotive is additionally equipped with emergency diesel generators or additional diesel generator compartments to cope with sudden power outages, but it will increase transportation costs.

2. The development, production, and maintenance of electric locomotives and the construction, operation, and maintenance of the electrified railways require high costs and high-end technology, resulting in the construction difficulty and maintenance costs of the entire railway system being higher than those of non-electrified railways a lot of. If the electrified railway is built in an environment of economic poverty, sparse population, rugged terrain, and bad weather, it will impose harsh requirements on national or local financial pressure and technological level.

3. Electric locomotives rely on electrified railways. A large number of power grid and rail facilities will have certain safety hazards. If someone arbitrarily breaks into the railway or climbs on the roof, it will cause an electric shock. If the high-voltage grid of an electrified railway in a city block accidentally collapses, it will also easily cause electric shock.
