The wheel problems with Metro鈥檚 7000-series railcars could be more complex than originally thought, according to the transit system’s CEO.
As Metro investigators continue to work on a 鈥渞oot-cause analysis鈥� of the problems, 鈥淚 think they鈥檙e starting to get to the point where this may be, the root cause may be, a series of root causes,鈥� said Metro General Manager and CEO Paul Wiedefeld.
鈥淏ut they have not been able to find a particular issue that, when you get in there, you immediately just add a quick fix,鈥� he told Metro board members on Thursday.
Meanwhile, he said the agency is investing in technology 鈥� typically used by larger railroads 鈥� that will help measure wheelsets and more.
鈥淎s we start to understand this better, it鈥檒l be a tool to bring back the cars sooner,鈥� Wiedefeld said.
That technology will roll out in the coming weeks and be installed in three sites.
About 60% of Metro鈥檚 rail fleet has been sidelined in the wake of an October derailment blamed on the wheel problems.
Wiedefeld offered no new timeline on the return of the cars Thursday. Amid the root-cause analysis, the cars are not expected to return into service until April, at the earliest.
