Det blir moderna och modernare i Afrika

Hur hög är kontaktledningarnas spänning i Sydafrika?

Wikipedia skriver:

Different voltages are used for different types of trains. Most electrified trains run 3000 V DC (overhead); this is used primarily for commuter lines, and has been in use since the 1920s. During the 1980s, higher voltages (25 kV AC and —much less frequently— 50 kV AC (both overhead) have been used for heavy duty lines (also more sleepers per kilometer), primarily in the transport of iron ore.

Man tackar.

Undras om det finns flerströms-lok man kan ju inte separera tåg och trafik hur mycket som helst.
