Power Rail Ruler

The DTK power rail ruler has been developed to allow manual measurement of the horizontal and vertical position of the power rail relative to the track. It works reliably on the third rail in compliance with the regulations for use and safety.

Measurement ranges:

  • Vertical: top edge of railhead to bottom edge of power rail:

185mm - 310mm

  • Horizontal: front edge of power rail - inner edge of adjacent rail:

556mm - 640mm


This measurement ruler is ideal for mobile use. Its overall weight is about 6 kg. An intelligent power supply ensures that the batteries need not be replaced over a prolonged period.
