|Title||Metropolitan Line railway between Watford and Moor Park Sun glints on the trackwork around the southern end of the eastern arm of the "Croxley Triangle". Just visible to the left is the trackbed of a former siding that ran along the Grand Union Canal. The photograph illustrates the way in which electrical power is provided to London Underground trains. The outer and central rails are both non-running, where the former is energised at +420 volts DC, and the latter at -210 volts DC, which combine to provide a traction voltage of 630 volts DC.|
