Ask a real train driver or fireman questions about how engines work, railways operate or anything else. If we do not know the answer, we will find out!

Vale's Estrada de Ferro Carajas (EFC) Heavy Haul

Post by Robert McDonald »

Greetings,

Would like to pass along to those of you interested in the longest iron ore
Heavy Haul corridor, one of Vales operations in Brazil, the broad gauge 1600mm
EFC.

One very noticeable characteristic these roads share is the piercing hum of the
rails. Has anyone analyzed HOW that is being created, and WHAT FREQUENCY
RANGES are generated.

Inquiring minds need to know ...

Regards,
