We offer the very best services in our field. We never settle for second best, and always have your satisfaction as our top priority. It’s who we are, and we are proud of it.

MAJOR CONTRIBUTIONS

• Directive Drawings
• Standard Drawings
• Manual of Design Criteria through Rev. 9
• General Plans & Profiles
• Track Plans
• Electrical Distribution, including Passenger stations AC and DC Traction Power Substations locations and ratings
• 3rd rail schematics
• Power company (PEPCO & VEPCO) coordination

MAJOR UPGRADES FROM ORIGINAL DESIGNS

• Introduction of low resistance aluminum-steel composite 3rd rail for better voltage regulation for train operations.
•  Introduction of low smoke and zero halogen for power cables in underground facilities and tunnels for life safety.
• Introduction, designs and execution of 3rd rail heaters for snow management.
• In-fill passenger stations like NY Ave in RED Line and optimization of costs for system elements such as additional tie- breaker station instead of an additional traction power substation.
• Design of in-line new double crossover and associated 3rd rail power distribution at Dunn Loring Station with minimal disturbance to full revenue operations.
• Analysis and design for upgrade of existing traction power system from 6-car train operation at 150 seconds headway to 8-car train operation at 90 seconds headway. 
• Final designs, installation, testing and commissioning of over 60 existing TPSS from 4 MW rating to 9 MW rating and replacement of major AC and DC switchgear, cables etc. 
• Upgrading the entire DC distribution to the Sate of good repair and compatible with new WMATA vehicles and revenue operations.
• Analysis and recommendations to assist WMATA in reducing construction time and delays for complete rather than limited power outage for safety and cost reductions.
• Isolation of Yard and shops from main-line third rail power distribution to minimize stray currents and safety to working personnel from high voltage shocks.

NEW TECHNOLOGY



• Design and assistance in introducing round-cell acid and gel station batteries for safety, reliability and longevity in the AC passenger Stations and traction power facilities.
• Design and assistance in introducing solid -state multi function protective relays and associated technology for remote monitoring and control of AC Passenger stations and DC traction power substationsNew Paragraph
