Section Switches

These are older versions of those in the previous image, the most obvious difference being the 'pointy roofs'. This image was added as a result of feedback.

Anyway, as per the previous caption:
Traction current (power rails) is supplied in several sections throughout the line. It is then split further by using section switches, as shown here.

Note to any idiots viewing here - there are bare metal parts inside these boxes, which have up to 430 volts going through them - it will kill you!!
