Mayor Antonio Villaraigosa quickly replaced appointees to the Metrolink board after the Sept. 12 crash that killed 25 people. At tomorrow's Metro Board meeting (where they will also be discussing late-night subway service), he'll be introducing motions to "add a second engineer to each locomotive cab, install video cameras and digital video recorders in the cab, implement 'automatic train stop' technology as an interim solution while positive train control is being developed, and establish an independent 'Commuter Rail Safety Peer Review Panel' to advise Metrolink on immediate and long-term improvements that will increase safety, reduce the risk of a catastrophic event, and focus on creating safety redundancy on Metrolink commuter rail network," according to Villaraigosa's office.
