11. Key Trains • Defined as: • One tankcar load of ppoison or toxic inhalation hazard (PIH or TIH), anhydrous ammonia (AA) or ammonia solutions • 20 carloads or intermodal portable tanks of a combination of PIH, TIH, AA, ammonia solutions, flammable gas, Class 1.1 or 1.2 explosives, and environmentally sensitive chemicals • One or more carloads of spent nuclear fuel (SNF) or high level radioactive waste (HLRW) • Restrictions: • Maximum speed of 50 MPH • Unless siding is rated as Class 2 or higher, key train holds main track • Car must be equipped with roller bearings • If visual inspection cannot confirm a defect bearing reported by a wayside detector, train will not exceed 30 MPH until passing next detector or inspection • If second wayside detector confirms defect, car must be pulled off of train Source: Association of American Railroads, Battelle Memorial Institute

12. Key Routes • Any track carrying a combination of 10,000 carloads or intermodal portable tank loads of hazmat, or a combination of 4,000 loads of PIH/TIH, AA, flammable gas, Class 1.1 or 1.2 explosives, environmentally sensitive chemicals, SNF or HLRW in one year • Requirements: • Wayside bearing detectors or equivalent technology no more than 40 miles apart • Main line track inspected by rail defect detection and track geometry cars or equivalent no less than 2 times/year; sidings no less than once per year • Periodic inspections of main track and sidings for cracks or breaks in joint bars Source: Association of American Railroads, Battelle Memorial Institute

13. Yard Operating Practices • Coupling speeds of loaded tank cars not to exceed 4 MPH • Loaded PIH/TIH, AA or flammable gas cars cut off in motion in no more than 2-car cuts • Cars cut off in motion coupled to loaded PIH, TIH, AA or flammable gas cars in no more than 2-car cuts Source: Association of American Railroads, Battelle Memorial Institute

14. Rail Hazmat Routing Regulations (HM-232)* • Applicability • Explosives 1.1, 1.2, 1.3 greater than 5,000 lbs • Bulk quantity of PIH/TIH materials • HRCQ radioactive materials • Route Analysis • a.Use specified routing factors to analyze safety and security risks for current routes • Alternative Route Analysis • a.Identify at least one “commercially practicable” alternative route and analyze safety and security risks • Route Selection • Select route posing the “least overall safety and security risk”; annual review required • Institute measures to address vulnerabilities and risk identified • Restrict distribution and access to data and routing analyses as sensitive security information (SSI) *49 CFR Part 172 contains this requirement

15. Rail Hazmat Routing Regulations (HM-232) • Completion of Route Analysis • a.Comprehensive, system-wide review of operations that could impact safety and security analyses every five years • Limitations on Actions by States • a. States, political subdivisions and tribes may not designate, limit or prohibit use of any rail line unless obtain waiver of preemption • Storage and Delays in Transit • a. Minimize time in transit; procedures for notifications; restrict access; etc. • Compliance and Enforcement • a. Not required to submit analyses or route decisions, but must have available for inspection

16. Rail Route Analysis Factors • Volume of hazmat • Rail traffic density • Trip length • Railroad facilities • Track type and class • Track grade and curvature • Signals and train control systems • Wayside detectors • Number and types of grade crossings • Single vs. double track • Frequency and locations of track turnouts • Proximity to iconic targets • Environmentally sensitive areas • Population density • Venues along route • Emergency response capability along route • Areas of high consequence • Passenger traffic • Speed of train operations • Proximity to en route storage or repair facilities • Known threats (from TSA) • Measures in place to address safety and security risks • Availability of alternative routes • Past incidents • Overall time in transit • Training and skill level of crews • Impact on rail network traffic and operations Source: Battelle Memorial Institute

17. Differences in Highway and Rail Routing of Hazmat • Private vs. public right-of-way • Fewer routing alternatives between any given origin-destination pair for rail • Larger quantities per container by rail • Train consists vs. individual trucks • Carrier interchanges by rail • Population proximity to right-of-way along route • Avoiding urban areas/center cities more difficult by rail Source: Battelle Memorial Institute

18. Different Approaches In Applying Routing Criteria • Require a route to pass across a segment that presents a low risk. • Require a route to avoid a segment that presents a high risk (i.e., hot spot). • Allow a route to use a high-risk segment, but impose a penalty (i.e., added cost) to any candidate route that would include that segment.

21. Community Activism • Communities located along major hazardous materials transport routes have long feared the possibility of a hazardous materials release. • There have been historic occurrences of such events with severe consequences (e.g., Graniteville, SC). • Organized opposition has often formed to dissuade carriers from moving particularly dangerous hazardous cargo through a community (NIMBY – not in my backyard). • Hazmat shippers and carriers are actively working with these communities to improve hazmat transport safety and security, through such initiatives as: • TRANSCAER (Transportation Community Awareness and Emergency Response) • Participation in State Emergency Response Commissions (SERCs) and Local Emergency Planning Committees (LEPCs) • Hosting Capability Assessment Programs (CAPs)

22. Key Takeaways • Hazardous materials shippers select preferred modes based on the characteristics of the cargo and the ability of the mode to satisfy the desired transport requirements. • Hazmat route selection is heavily regulated for the truck and rail industry, in terms of designated routes and requiring route risk assessments that consider a variety of economic, safety, security and environmental factors. • Tradeoffs exist among routing options in terms of their ability to satisfy various criteria, leading shippers, carriers and regulators to identify preferred routes based on criteria importance.

23. Student Exercise • The table below presents the results of an analysis that was performed on six hazardous materials highway routing options. • Based on the information provided, which route would you select as the preferred option? Explain your method and show how it was applied in determining the preferred route. • Report back on your methodology during the next session for comparison with others to identify the most desirable method(s).
