This is a short section of third rail.

Pick-ups on the train run along this rail to collect the 750v DC electricity to power the train. There are gaps in these third rails at various places, such as level crossings. The train having several pick-ups ensures there is always one or more in contact with the rail.

Obviously this rail is purely for demonstration and is not connected to anything.

With the rail carrying 750v DC it would not be a good idea to get near or touch it.
