Low-frequency-16.7z -

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

Technical drawings or data for the 110 kV high-voltage distribution systems that feed these specific railway grids. Regional Usage low-frequency-16.7z

Early electric locomotives used "brush-type" AC/DC motors that operated much more efficiently at lower frequencies. This frequency is standard for major European operators
