Low-frequency-16.7z ⇒

This specific frequency is a historical and technical standard used primarily for train traction. While most public power grids run at 50 Hz or 60 Hz, these railway systems operate at a lower frequency for several key reasons:

Early electric locomotives used "brush-type" AC/DC motors that operated much more efficiently at lower frequencies. low-frequency-16.7z

Lower frequencies reduce reactive power production in AC cables, allowing for active power transmission over longer distances with fewer losses. and SBB (Switzerland).

This frequency is standard for major European operators like (Germany), ÖBB (Austria), and SBB (Switzerland).
