Thieves stole 70,000 pounds of copper cable from Sound Transit’s Link light rail line between Tukwila and Sea-Tac Airport, the agency reported Friday.
Thieves ripped the wire from inside an elevated guideway that supports the tracks, probably over the last several months. From end-to-end, about four miles of cable was stolen, Sound Transit spokesman Bruce Gray said.
“This isn’t something that would have been done overnight,” Gray said. “Whoever did this knew what they were going after and had some sophisticated knowledge of how to get in.”
The wire runs along the guideway’s hollow interior to protect it from low-level electrical current that strays from the rails, and directs it to the ground. The current would otherwise corrode the structure’s rebar over time, Gray said.
