GERT8000-M1 Iss 7

A review has been carried out of the use of detonators as a form of protection. It will no longer be necessary to use detonators to protect a portion of a divided train that has been left in section. Instead, a red light must be displayed on the rear of the divided portion, and a white light on the front. Section 5.4 has been revised to reflect this.

A new section 5.5 has been introduced to describe the instructions the signaller must give to the driver and those that the driver must carry out for the assisting train that is to remove a divided portion of a train. These have not previously been spelt out.
