GERT8000-TS3 Iss 7
Absolute block regulations
Synopsis
Summary Of Changes
Regulation 3.1.4 has been revised to regulation has been changed to state when the 'is line clear' signal can be sent.
Regulation 3.6.1 has been revised to explain that 'blocking back inside home signal' must be applied not only when there is a work-site marker board for a T3 possession obstructing the line within the clearing point, but also when there is work that will make the line unsafe within that work site.
Most of the wording in Regulation 3.6, Part C, ‘Blocking the line for protection of staff or work’, has been revised to explain the procedure in detail, and a new diagram included to illustrate this.
Regulation 10.5 has been revised to replace incorrect cross references to modules T3 and TS1 by a correct reference to Signal Box Special Instructions.
