In over forty years of service to the railway and transportation industry, PTSI Transportation has found its market niche in areas not well served by other consultancies. For the railway industry, these include customer and on board service, operations training tools, and management systems and standards. Railway passenger equipment (including appraisal and residual value optimization) has been a long-standing specialty. For the rail and bus transit field, customer service and operations training tools again, along with public-private interface, have become our major disciplines.
