Conduit current collection

When trains use electricity to move, we need to somehow give them that electricity. One way is to use something called "conduit current collection".

Think of it like a straw: the electricity flows through the train tracks (like liquid flows through a straw), and we need to suck it up (like we use our mouths to suck liquid up a straw). But we can't use our mouths, so the train uses something called a "collector shoe" instead.

The collector shoe is a piece of metal that slides along a wire (it's a long, thin metal line) above the train tracks. When it touches the wire, the electricity flows from the wire into the collector shoe, and then into the train.

So, instead of plugging in the train like we plug in a phone or a computer, the train is taking energy from the wire through the collector shoe as it moves along the tracks.

It's like a giant, invisible straw that powers the train!
