1Comparing and Contrasting Highway and Rail
Routing
- TRB 86th Annual Meeting
- January 23, 2007
- Washington, DC
- John Allen, Battelle
- Robert Fronczak, AAR
2Overview of Presentation
- Differences between highway and rail
- Regulatory perspective
- DOT regulatory approach highway vs. rail
- HM-232E New proposed rules for rail routing of
selected HM - Comparison of routing factor lists rail vs.
highway - Current rail industry routing practices
- Observations on rail routing issues
3Some Major Differences Highway and Rail Routing
of Hazmat
- Private vs. public right-of-way (ROW)
- Fewer routing alternatives between any given
origin-destination pair for rail - Train consists vs. individual trucks
- Carrier interchanges by rail
- Population proximity to ROW along route
- Avoiding urban areas/center cities more difficult
by rail - Beltways or bypasses often available by road
- Larger quantities per container by rail
4Regulations
- Highway
- Highway HRCQ 49 CFR 397 Subpart C
- Highway Route Controlled Quantities RAM
- Highway NRHM 49 CFR 397 Subpart D
- Placarded Hazmat
- Rail
- Rail Hazmat - NPRM Docket HM-232E
- Explosives 1.1, 1.2, 1.3 HRCQ Bulk TIH
5General Approach to Regulate Hazmat Routing
- Highway RAM and HRCQ
- Base rule Follow Statedesignate route or
Interstate system highway selected to reduce time
in transit for HRCQ - Route analysis/designation responsibility
State/tribal/local government requirements - Coordination continuity, jurisdictional, public
process - Guidelines for analysis simplified qualitative
criteria - Highway Non-Rad Hazmat (NRHM)
- Base rule Follow State-designated route or
simply operate over routes which do not go
through heavily populated areas, places where
crowds assembled, tunnels or alleys. - Route analysis/designation responsibility
State/tribal/local government requirements - Coordination continuity, jurisdictional, public
process - Guidelines for analysis simplified qualitative
criteria
6General Approach to Regulate Hazmat Routing
- Proposed Rail Hazmat
- Base rule Annually review and select route
posing the least overall safety and security
risk based on commodity data collection, routing
analyses, and Rail Risk Factors - Route analysis/designation responsibility rail
carrier - Coordination strictly internal except with
connecting carriers - Guidelines for analysis Rail Risk Factors
(listed in Appendix D)
7HM-232E Notice of Proposed Rulemaking (Proposed
49 CFR 172.820)
- a. General/Applicability
- Explosives 1.1, 1.2, 1.3 greater than 5000 lbs
- Bulk quantity of TIH materials
- HRCQ radioactive materials
- b. Commodity Data
- Collect commodity data by routes
- c. Route Analysis
- Route is one or more line segments between
beginning and endpoints of the carriers
possession - routes for analysis determined by
rail carrier - Use data collected and Appendix D Routing Factors
to analyze safety and security risks for current
routes - d. Alternative Route Analysis
- Identify at least one commercially practicable
alternative route and analyze safety and security
risks
8HM-232E Notice of Proposed Rulemaking
- e. 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 SSI - f. Completion of Route Analysis
- Must complete analysis by end of calendar year
after data collection and analyses - Comprehensive, system-wide review of operations
that could impact safety and security analyses
every five years - g. Limitations on Actions by States
- States, political subdivisions and tribes may not
designate, limit or prohibit use of any rail line
unless obtain waiver of preemption - h. Storage and Delays in Transit
- Minimize time in transit procedures for
notifications restrict access etc.
9HM-232E Notice of Proposed Rulemaking
- i. Recordkeeping
- - Must make analyses available upon request
during inspection retain for two years - j. Compliance and Enforcement
- Not required to submit analyses or route
decisions, but must have available for inspection
- Inspectors may require changes in route decisions
based on review of material on file - Appendix D List of Rail Risk Analysis Factors

12Current Railroad Practices Related to Routing
Hazmat (OT-55-I)
- OT-55 are AARs Recommended Operating Practices
for Transportation of Hazardous Materials - Originally a result of the Inter-Industry Rail
Safety Task Force (AAR CMA RPI) first
published January 4, 1990 - Provisions include
- Key Trains Key Routes
- Yard Operating Practices Storage
- TRANSCAER Shipper Notification
- Time Sensitive Materials SNF HLRW
13Key Trains
- 5 car loads of PIH/TIH or anhydrous ammonia (AA)
- 20 car loads of intermodal portable tanks of TIH,
AA, Flammable gas, class 1.2 or 1.2 explosives,
and environmentally sensitive chemicals - One car load of spent nuclear fuel (SNF) or high
level radioactive waste (HLRW) - Restrictions
- Maximum speed 50 MPH
- Unless siding is Class 2 or higher, key train
holds main track - If visual inspection is not able to confirm a
defect from a wayside defect detector, the train
will operate at 30 MPH until next defect
detector, or terminal inspection - If second defect detector confirms initial defect
detector reading, car must be set out
14Key Routes
- Any track carrying a combination of 100,000 car
loads of IPTs of hazmat, or a combination of
4,000 loads of PIH, AA, FCG, Class 1.1 or 1.2
explosives, ESCs, SNF or HLWR in one year - Requirements
- Wayside bearing detectors or equivalent
technology no more than 40 miles apart - Main line track inspected by defect detection and
track geometry cars or equivalent no less than 2
times/year - Sidings no less than once per year
- Main track and sidings will have periodic
inspections for cracks in joint bars
15Yard Operating Practices
- Coupling speeds not to exceed 4 MPH
- Loaded TIH, AA, FG cars cut off in motion in no
more than 2-car cuts - Cars cut off in motion coupled to loaded TIH, AA,
FG cars in no more than 2-car cuts
16Storage Separation Distances for new facilities
(loaded tank cars and storage tanks from main
line Class 2 track or higher)
17Observations about rail routing
- Differing factors produce different routes
- From a rail safety standpoint, generally the
shortest route is the best route (fewer miles and
derailment rate dictate) - Flexibility of the carrier is needed in
determining the best route for operational
considerations there is no one answer or
methodology - Rail carriers are flexible in working with
shippers in establishing routes - If everyone bans hazmat through jurisdictions,
sooner or later there will be no hazmat
