The Development of Standards
for the Rail Transit Industry
Project TCRP G-4
APTA Rapid Rail Conference
June 2000 - St. Louis
Thomas J. McGean, P.E.
TCRP G-4 PROGRAM
• Project Begun in 1996
• Sponsored by FTA, Administered by TRB and
TDC (APTA)
• Approach
– establish an institutional framework for
developing transit standards within IEEE
and ASME engineering societies
– demonstrate the process by developing one
or more needed standards
WHY TCRP G-4 USES
ENGINEERING SOCIETIES?
• Automatic ANSI Certification
• Complies with PL 104-113 & OMB A-119
• Rules, Procedures & Oversight already in place
at no cost to transit industry
• Professional standards experts available to
assist at no cost
• Large reservoir of existing case law
• IEEE & ASME assume standards liability risk
CONSENSUS STANDARDS
PRINCIPLES
• Must be present to meet PL 104-113

•
rationalize procurement process
reduce “custom engineering”
simplify maintenance activities
reduce spare parts inventory
reduce training costs
Introduction of Microprocessors
Makes All of These More Critical
– IEEE 1473 Alone Estimated to Save NJT
$420K/year
