Challenges Facing Freight Rail
News reports of large train derailments, combined with a litigious U.S. tort system and the potential for nuclear
verdicts that underwriters have difficulty quantifying, are creating a liability risk challenge for U.S. freight
railroads.
Beyond liability risk concerns, property and business interruption losses are mounting as climate change increases
the frequency and severity of natural catastrophes.
“The concern with the larger railroads is the business interruption exposure related to floods,” Tolbert adds. "They
must move all of their assets away from where storms are occurring and reposition them strategically. But doing so
typically interrupts the network activity and may potentially generate BI losses.”
Natural catastrophes also hinder rail globally. In the UK, weather-related incidents caused more than 322,000 delay
events between 2006 and 2021. Canadian heatwaves and wildfires forced trains to run slower, contributing to a 26
percent revenue reduction for the Canadian National Railway.
Wildfires in Canada, the western U.S., and Europe lead to track damage, which contributes to derailments, power and
communication disruption and increased soil erosion. New Canadian rules require railroads to commit additional
capacity to detect, monitor and suppress fires during the midyear wildfire season. To improve resilience, the rail
industry is turning to technology, including satellite imagery, to monitor vegetation growth near tracks. Further,
fire trains are being deployed by North American railroads to combat wildfires that can destroy tracks, bridges and
other assets.7
With just six class 1 freight railroads operating in the U.S., the risk pool is diminished. Increasingly, larger
railroads are choosing to self-insure and reduce the amount of risk transferred to traditional markets.
“They are getting comfortable with this approach, which makes it less likely they will come back to the risk transfer
markets,” explains Tolbert. “Every year, underwriters tell us that the pool of risk is more concentrated than ever.
Insurers don’t have the luxury of the spread of risk because there are only six class 1 freight operators. Thirty
years ago, there were more than 30.”
Concerns over nuclear liability verdicts and the rising frequency and severity of natural catastrophes have led to
insurance market constriction. Most rail insurers are concentrated in Bermuda and the UK. Capacity is retracting and causing difficulties. Pricing is also a challenge, as excess liability premiums have increased at each layer, but especially at the top of the risk tower.
“There’s a big fear of the runaway jury verdicts in the U.S., so in general, insurance companies are more tentative,
especially where you are dealing with heavy industrial targets,” Tolbert adds.
