It's not just steamship lines charging fuel surcharge

We forget that railroads in the U.S. are still somewhat regulated.

They have been charging fuel surcharges, but now customers are questioning if these are justified.

Some shippers want to shake things up even more. A collection of mostly small customers is taking on the rail industry’s fuel surcharges in a federal court case seeking class-action status. That case entered its evidence discovery phase as 2008 ended, so 2009 could be a crucial year of judgment on railroads’ fuel fees.

I find it a bit surprising the FMC isn't looking into bunker adjustment factors being charged by ocean carriers. After all, some people think the FMC should be abolished, and one would think they want to demonstrate they have a reason to exist.
