Mexico-to-US intermodal rail service

DP World, the international port container terminal operator, is beginning a new rail service from Mexico to the US for automobiles. It will use 53-foot containers to move the cars by truck or rail. That makes the containers compatible with the standard size container used in the US and Mexico as well, rather than the 40-foot ocean containers. That eliminates a need to transload for US road transport.

It’s a good idea. Large quantities of cars are made in Mexico for the US market. The business is growing, because some automotive components made in China face trade barriers when ocean shipped directly to the US.

Intermodal transport by rail over long distances will reduce emissions considerably. A properly engineered service could compete in travel time with road haulage to a distribution point.

Railroads have notorious problems with reliability of service; they have trouble predicting when arrival may occur. According to rail experts, this is largely due to delays that occur in switching yards, which can be unpredictable in length. And when one stopover in a yard is delayed so the next outbound train is missed, days can be added to transit times.

However, auto transport in containers like this has advantages.

First, at the destinations, cargo owners have some buffer storage, so delayed delivery is seldom critical to business.

Second, the container cars can be mixed and matched on trains, so if some are ready, they can make the train for the next leg; others can wait for the next train. All the containers in the original train needn’t go together. My rail expert thinks this ability to make shorter trains is key to making rail transport more reliable and yard performance more efficient.

Third, intermodal transport of containers has been shown to reduce emissions over individual container transport by truck. That’s important for many shippers today, due to public companies’ need to report Scope 3 emissions.

Finally, there’s a growing demand for car transport from Mexico. The country is proving to be a dependable place to locate auto factories, with adequate labor supply and manufacturing knowledge. There should be plenty of business for DP World.

Water isn’t rising on Mississippi, but barge rates have steadied for now

America’s most prominent inland waterway for commerce is the Mississippi River. It’s been plagued this year by low water. There hasn’t been enough rain in the middle of the continent.

Low water causes barges to run aground, and the remedy is to put less in them, reducing the capacity of the routes. That has been the state of affairs on the river this year as we get into grain harvesting times. The majority of grain exports from the US are from the Gulf Coast, using the Mississippi as the feeder.

It’s a financial blow for farmers and their co-ops if grain deliveries slow. Grain is one of the most important of the US export products, and helps to reduce our balance of payments.

You would think that freight rates would go sky high. But they appear to have steadied right now, in harvest season.

The United States Department of Agriculture (USDA) publishes a Grain Exports Dashboard showing numerous statistics. Grain exports from the US are down from both Gulf Coast and Pacific ports this year.

An interesting aspect of the article below is the water level graphs from the United States Geological Survey (USGS). These show a deficit of more than 10 feet at Memphis, and around 3 ft currently at St Louis. Accordingly, drafts of barges have to be reduced, as much as 32% at St. Louis.

Maintaining conditions for commerce on the Mississippi is the responsibility of the US Army Corps of Engineeers.

Grain exports from the Mississippi have been an interest of mine since 2012, when Chris Clott and I and other authors wrote about soybean exports.

Bulk carriers and containerships moving at slowest speeds

Slow steaming is a good way to save on fuel costs and meet the new IMO requirements. So ships have slowed down. But I was amazed at the graph below, showing a trend for quite a while.

Slowing down is an important way of cutting CO2 emissions from fuel oil. It also implies that more ships are needed to meet planned sailings on a scheduled route. It’s a deliberate reduction of individual ship ‘productivity’, since fewer paid cargo-carrying trips can be made in a year. But it may be a better fit with the demand for shipments right now, and it might result in fuller vessels.

We should remember that slow steaming will not eliminate CO2 emissions problems; it’s a stopgap at best. New types of power with very low or zero emissions through their life cycle well-to-wake must be developed. The investments have to be made.
