Depot Isolation Facilities

Following a fatal accident to an operative in an electrified depot, Network Rail and one of its train operators jointly commissioned a proposal to provide a permanent solution to the requirements of an ORR improvement notice.

Antagrade were invited to assist in finding a solution to ensure that the conductor rails within depot sheds were able to be isolated and effectively bonded without affecting other depot operations.

The systems are now fully commissioned into service and enable train drivers to position stock within the sheds and to implement a fully secured isolation of stabled vehicles with the conductor rail status clearly enunciated to all other depot staff.

Antagrade were commissioned to:

Prepare and present:

  • A detailed functional specification
  • Options for implementation

Develop the agreed solution to a design for construction

Procure, install and commission:

  • Civil and cable route works
  • Isolation and bonding equipment
  • High-intensity overhead power status indicators
  • Modifications to conductor rail and bonding cabling configurations
