At Orange Line Metro Rail Transit System, I maintain and troubleshoot critical Automatic Train Control, ATP, ATO, ATS, and signaling subsystems for NORINCO-GMG-Daewoo (JV).
I reduced CBI subsystem faults by more than 50%, from 27 to 13, and reduced DCS faults by 86%, from 7 to 1. I also conduct train dynamic testing, server monitoring, log retrieval, and playback-data review.
Previously with Pakistan Railways, I supervised signaling and telecom installations under the Signal Rehabilitation Project alongside Bombardier Transportation and China Railway Signaling Corporation.
I bring over 12 years of hands-on railway signaling experience, including point machines, axle counters, relays, optical fiber installation, safety protocols, inspections, testing, and system documentation.
