Why can birds sit on the third rail?

TIL Rats and birds don't get electrocuted by the third rail because they don't form a grounding connection. This is not some property inherent to rats and birds. This is because when they touch the third rail, they aren't touching anything else.

Why is the 3rd rail electrified?

Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a conductor rail) for the purpose. On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some systems a central conductor rail is used.

Will high speed rail be electric?

High speed trains run on electricity instead of diesel fuel. Because much of the world's electricity is still generated at fossil fuel burning power plants, high speed trains do contribute to carbon emissions, however the climate impact of one train is significantly less than that of many personal vehicles.

They are also used for acknowledging signals given by railroad employees, such as during switching operations.

Why aren t rats electrocuted by the third rail?

This is why birds do not die from landing on power lines, and subway rats do not get electrocuted even if they run across the third rail; they are not bridging the energized wire or rail to a grounded part of the structure.
