Hornsey depot has recently installed a new high-level full-length gantry, servicing Roads 18 and 19, to help depot staff meet the demanding maintenance schedule for the Thameslink fleet.

Zonegreen have modified their existing interlocking system to ensure that staff working on the new gantry are protected from the 25KVA overhead line (OLE) and the risks associated with working at height.

The access gates to the gantry are interlocked such that they can only be unlocked when the OLE has been isolated. Each gantry has three egress hatches to offer a means of escape in the event of emergency. These egress hatches are monitored by the Zonegreen interlocking system to ensure that they are all fully closed before the OLE can be re-energised.
