The two wires don't contact (although the bow collector or pantograph is briefly in contact with both equally wires).

The locomotive would turn into trapped, but mainly because it passes the segment crack the pantograph briefly shorts The 2 catenary lines. If the other line is de-energized, this voltage transient may journey offer breakers.
Line tensioning in Germany Catenary wires are stored in mechanical tension as the pantograph will cause mechanical oscillations while in the wire.
A CLI is utilised When a considerable vocabulary of commands or queries, coupled with a wide (or arbitrary) variety of possibilities, is often entered a lot more fast as textual content than using a pure GUI. This is often the situation with working program command shells.
