Abstract
Scandia, Inc., is a commercial vessel management company located in the New York Metropolitan area and is part of a family of firms including Scandia Technical; International Tankers, Ltd.; Global Tankers, Ltd.; Sun Maritime S.A.;Adger Tankers AS; Leeward Tankers, Inc.; Manhattan Tankers, Ltd.; and Liuʼs Tankers, S.A. The companyʼs current market niche is the commercial management of chemical tankers serving the transatlantic market with a focus on the east and gulf coast of the United States and Northern Europe. This three-part case describes the commercial shipping industry as well as several mishaps that the company and its President, Chris Haas, have had to deal with including withdrawal of financial support by creditors, intercorporate firm conflict, and employee retention. Part A, which was published in the Fall 2010 issue, presented an overview of the commercial vessel industry and set the stage for Parts B and C where the firm℉s operation is discussed.

Abstract
Purpose
At the US passenger stations, train operations approaching terminating tracks rely on the engineer’s compliant behavior to safely stop before the end of the tracks. Noncompliance actions from the disengaged or inattentive engineers would result in hazards to train passengers, train crewmembers and bystanders at passenger stations. Over the past decade, a series of end-of-track collisions occurred at passenger stations with substantial property damage and casualties. This study’s developed systemic model and discussions present policymakers, railway practitioners and academic researchers with a flexible approach for qualitatively assessing railroad safety.
Design/methodology/approach
To achieve a system-based, micro-level analysis of end-of-track accidents and eventually promote the safety level of passenger stations, the systems-theoretic accident modeling and processes (STAMP), as a practical systematic accident model widely used in the complex systems, is developed in view of environmental factors, human errors, organizational factors and mechanical failures in this complex socio-technical system.
Findings
The developed STAMP accident model and analytical results qualitatively provide an explicit understanding of the system hazards, constraints and hierarchical control structure of train operations on terminating tracks in the US passenger stations. Furthermore, the safety recommendations and practical options related to obstructive sleep apnea screening, positive train control-based collision avoidance mechanisms, robust system safety program plans and bumping posts are proposed and evaluated using the STAMP approach.
Originality/value
The findings from STAMP-based analysis can serve as valid references for policymakers, government accident investigators, railway practitioners and academic researchers. Ultimately, they can contribute to establishing effective emergent measures for train operations at passenger stations and promote the level of safety necessary to protect the public. The STAMP approach could be adapted to analyze various other rail safety systems that aim to ultimately improve the safety level of railroad systems.
