... Other activities documented the influence regulations in the selection and implementation of technology; for example, adoption of grade crossing warning systems; and systems designed to identify specific hazards such as derailed freight equipment or shifted loads. The team also contacted train control system suppliers and entities planning or implementing train control system improvements or enhancements, to identify prospective equipment and technology.

... The team probed the niche and content of Rules and Procedures to understand their limitations as well as the administrative resources essential to support and enforce them. In a further effort it gathered information on techniques that are not dependent on train control technology, and a variety of operating procedures that can be employed to prevent collisions and increase the overall safety of shared railway environments.

... Task 8: Business Model The consultant team developed a business model and combined information about the experiences of North American shared-use operations discussed in the Task 5 report, with the characteristics identified in Task 7. The business model includes: • Approach to liability, indemnity, and insurance • Ownership, rights, responsibilities and priorities, the pros and cons of public versus private ownership, and the relative ease and cost of public versus private financing TCRP A-27 Research Task Descriptions 95

... There are schedules, costs, and technical impacts associated with preparation and submission of a Waiver Petition to the FRA; • The potential benefits to the owner from investments made to improve and provide a highquality passenger operation that may also be advantageous to the freight railroad, through faster trip times as a result of better track quality or additional customers due to the improved service potential of the line. The Task 9 report lists and calculates both direct and indirect costs and benefits and builds a business case that can be used by agencies in support of a planned shared-use system.

... The specific activities in the risk analysis are: • Define risk measures and criteria for equivalent safety; • Estimate likelihood and severity parameters of each accident scenario for the case study and the variants; • Exercise the FRA risk model for the base case and variants using the FRA model. The case study produced in Task 10 examines the issues related to developing a viable shared-use system.
