Why Cars Stall on Train Tracks Is Not Due to Magnetic Fields! Here’s the Scientific Explanation

The myth that the magnetic fields from electric trains can suddenly shut down vehicle engines at level crossings has finally received a detailed technical explanation to address public concerns.

The narrative claiming that electric trains generate extraordinarily powerful magnetic forces capable of interfering with vehicle electronic systems—whether in Electric Vehicles (EV) or Internal Combustion Engine (ICE) vehicles—has been confirmed as a misconception with no valid scientific or engineering basis.

This clarification is crucial because safety at railroad crossings is often compromised by drivers panicking after falling for this myth.

According to Arief Hidayat MA., Eng., CEO & Founder of Wealthy Group, while magnetic fields in electric train systems do exist, their strength is strictly limited and measurable.

“Electric trains operate by drawing power from overhead cables or electrified rails to supply traction motors, which naturally create an electromagnetic field (EMF). However, this magnetic field has been deliberately designed to remain localized only around the train’s equipment and tracks,” he said on Tuesday (5/5/2026).

The characteristics of this magnetic field dissipate very rapidly with distance, so its strength will never be sufficient to affect the electronic modules of vehicles waiting several meters behind the crossing barriers.

Arief Hidayat emphasized that every automobile manufacturer equips modern vehicles with extremely strict electromagnetic compatibility (EMC) standards.

All electronic and mechanical systems in cars are protected and tested to withstand electromagnetic interference far stronger than what is produced during normal train operations.

If a vehicle stalls right on the tracks, it is not caused by external magnetic wave interference, but rather by internal vehicle factors or driver error.

“People need to understand that the correlation between a vehicle stalling on the tracks and the presence of a train’s magnetic field is not necessarily a cause-and-effect relationship. Often, it is the uneven or potholed condition of the crossing infrastructure that causes a drastic drop in RPM until the engine stalls, especially in manual transmission cars,” Arief explained.

Furthermore, he noted that in electric vehicles, system failures are often triggered by a weak 12V auxiliary battery or errors in the Battery Management System (BMS) reading due to heavy vibrations when crossing the tracks.

These vibrations can sometimes cause sensor anomalies that unintentionally activate the immobilizer system.

“It is far more important for vehicle owners to focus on routine maintenance of small components like the 12V battery and sensor systems, rather than worrying about magnetic radiation from trains. Modern train and car technologies have been designed to coexist safely without interfering with each other’s functions,” Arief added.

In conclusion, this myth persists only due to a lack of public understanding of how electromagnetic forces actually work. Railroad crossings are technically designed as safe zones for road traffic as long as safety rules are followed.

With technical evidence showing that the EMF strength of trains is far below the threshold that could disrupt automotive systems, concerns about the ‘deadly magnet’ phenomenon at railroad crossings can officially be dismissed with full confidence.

This education is expected to reduce driver panic, allowing them to drive more calmly and focus when crossing railway lines.
