Seaford rail line: Section of faulty cable to be replaced after wires snap a second time

Electric train services on Adelaide’s Seaford Line could be halted for weeks, after last month’s major failure left the line relying on a single, rare component.
9NEWS has learned the operation of the Seaford line is dependent on a single circuit breaker, a unique part for which there is no replacement available anywhere in the world.
The South Australian Minister for Transport and Infrastructure Stephen Mullighan has admitted that in the absence of a backup circuit breaker, another failure would have a much bigger impact on the rail network, stopping the train line indefinitely.
“It could be a period of some time, but we don't have an estimate on that,” he said.
“It certainly will be many days, but whether it's a period of weeks, we just don't have that information.”
The state government is working on contingency plans, which would either involve substitute buses – used during last month’s 36-hour stoppage – or diesel trains, shifted over from other lines.
“We can provide a level of service, but we can't guarantee that there won't be any inconvenience to people,” Mr Mullighan said.
Services on the Seaford line came to a halt for 36 hours last month, after one of two circuit breakers at the Lonsdale substation mysteriously blew up.
Since then, the state government has been trying to obtain a replacement from manufacturer, Siemens.
Construction and testing requirements have resulted in a delay in the delivery of the replacement circuit breaker.
An investigation into what caused the circuit breaker to blow is underway.
