Division 4.2.16.1 GeneralF1

The design of system separation sections shall ensure that trains can move from one power supply system to an adjacent different power supply system without bridging the two systems. There are two methods for traversing system separation sections:

1. (a)

   with pantograph raised and touching the contact wire;

2. (b)

   with pantograph lowered and not touching the contact wire.

The neighbouring Infrastructure Managers shall agree either (a) or (b) according to the prevailing circumstances.

The overall length D of neutral sections is defined in EN 50367:2012, clause 4. For the calculation of D clearances in accordance to EN 50119:2009, clause 5.1.3 and an uplift of S₀ shall be taken into account.
