Electric train is one of the most widely used transportation modes in Indonesia especially Jakarta. In general, all electrical and electronic based equipment when operated will produce electromagnetic fields. At present, the railway system uses electric power, both as to its driving force, as well as a supporting part (light system, air conditioner, etc.), and instead uses very large electric power. So surely the train system produces an electromagnetic field. Electromagnetic fields are a combination of invisible electric and magnetic fields of force. They are generated by natural phenomena, but also by human activities, mainly through the use of electricity. The magnetic field on the train generally occurs in areas close to the source. In this paper, already measured the magnetic field (near field) in the electric train in the frequency range 0.015 kHz up to 1 kHz. The measurement results show that the highest magnetic field is obtained when the train starts up at 333.76 nT. The magnetic field level is small when away from the electrical inverters. The average level of the magnetic field when the train is at its highest is 223.26 nT and during braking there is an increase of 323.93 nT.
