Reading the footnotes behind railroad market literature, “Intermodal does best in high-density traffic lanes over long distances.” Intermodal marketing, public relations and advertisements admit to this.
The growth hurdle is that there just aren’t many high-traffic volume lanes left to exploit. Growth year-over-year can continue. But it likely will not seize chunks of trucking’s share from the highways.
Where is the
If rail intermodal is going to take trucks off the highway network and simultaneously provide traffic relief to the road network, two maps illustrate where this geographically should occur.
Most of the truck and traffic congestion is east of the Mississippi River. Figure 1 identifies where the truck and auto highway congestion is located. Most market-to-market freight flows not yet using rail intermodal are nestled between these short-distance business clusters in the eastern part of the nation. This map is from a Brookings Institute Freight Analysis report. Federal highway studies by U.S. Department of Transportation and Federal Highway Administration planners project this concentration of traffic lane congestion will grow out largely in the eastern U.S. toward 2040. Much of the freight moves as smaller packaged shipments in 100-mile to less than 300-mile stretches.
From a public policy point of view, intermodal services that might be redirected from long-haul corridors to the much shorter, closely clustered markets in the eastern U.S. could help reduce local road accidents (Figure 2)—but only if a new intermodal business model evolved.
Figure 3 helps visualize where the short- to medium-distance freight markets are as a series of concentric market circles. Overwhelmingly, the nation’s markets are a series of short origin-to-destination locations. This concentric short-distance market pattern doesn’t fit the rail model because that rail model relies on double-stack container trains, which doesn’t cater to hauling semi-trailer trucks. It has to move containers. Not every shipper’s supply chain uses containers. Not every shipment can fit into a container.
The double-stack railcar does fit well as the engineering solution across the long western railroad routes. That’s where large day-to-day volumes of containers move between the western U.S. ports and the Midwest markets. This stacked intermodal carrying capability dates back to 1977, when the Southern Pacific and American Car & Foundry designed the first true double-stack railcar, capable of handling two 40-foot containers. Ocean carrier APL Lines initiated double-stack container trains around 1984 as a means to avoid the much longer transit times via the Panama Canal in order to deliver containers from Japan, Korea and China to the U.S. Midwest and East Coast markets. For the railroads, the long-distance stack train was indeed a market breakthrough. It offered exceptional economic improvement to the ocean carriers, the railroads and their customers.
A study for Burlington Northern Railroad by ZETA-TECH Associates in 1990 calculated a cost-to-move savings of 45% on the rail route from Seattle to Chicago. Other consultants later confirmed that estimate. And so, double-stack container trains became the primary intermodal model.
(Strengths/Weaknesses & Opportunities/Threats) Intermodal Analytics
The strengths of stack trains:
This SWOT opportunity made it possible to almost entirely reverse the trucking-dominated traffic flows between the Southern California markets and the Chicago/Midwest markets in the years between 1980 and 1990.
What are the apparent SWOT weaknesses? The biggest disadvantage is that the engineering advancements could only move containers, not trailers. The trucking market is largely semi-trailers. Another weakness is that stack trains require high volumes, as well as big terminals with expensive loading cranes. Not every railroad yard is easily converted to stack train service.
A SWOT threat is that the early units were fitted best toward moving the international maritime containers that are denominated in TEUs (twenty-foot equivalent units) and FEUs (forty-foot equivalent units). The threat to railroad business growth was that semi-trailers offered greater cubic capacity with 45-foot and 48-foot lengths. Then 53-foot-long trailers appeared.
The SWOT opportunity to build the market occurred in 1990, when the Burlington Northern purchased its first order of domestic 53-foot containers. The railroad acquired about 25,000 of these containers. The other railroads followed by adopting the 53-foot stackable containers as the new intermodal model.
By about 1996, it became clear that, with high volume lanes, the competitive distance favoring rail intermodal was in the 750-mile range. A few markets might have presented a 500-mile or so competitive distance opportunity.
The problem child for intermodal became the old TOFC (trailer on flat car) semi-trailer market segment. Moving trailers on intermodal trains has been in an unquestionable long-term decline. In periods of extreme high traffic demand and low supplies of drivers or trucks, we see occasional spikes in TOFC volumes. This happened at times in 2018. However, the TOFC spike fades and the loss of TOFC volume reappears. If there is a SWOT opportunity for a return of TOFC volume to the railways, it probably requires the invention of an affordable new rapid load/unload mechanical railcar.
Another strategic opportunity could be short-distance inland port hubs. A 2003 study suggested that dedicated shuttle trains might be viable for moving maritime containers between the Port of New York/New Jersey and as many as 10 inland port terminal depots. Among these were three proposed hubs in New York State and one in Pennsylvania: Albany (150 miles), Syracuse (284 miles) Buffalo (437 miles), and Pittsburgh (427 miles).
None of this happened. Yet, there are rumors of a possible hub near Syracuse as CN acquires the CSX Syracuse-Montreal branch line. Time will tell if this works.
So far, the evidence is clear that CSX and Norfolk Southern couldn’t make short-haul intermodal a profitable business model. Neither could the port authorities. However, there are a few exceptions that might suggest short-haul optimism.
Virginia and West Virginia started two inland ports. The one in West Virginia is closing. The Virginia hub continues but hasn’t really expanded. Georgia, North Carolina and South Carolina are operating or proposing several inland container port depots.
Research suggests that there is some form of subsidy required to make the current inland port model work. There is no published information that shows that these short-haul patterns are independently sustainable as a pure private business capital and operating investment. In contrast, the long-haul intermodal lanes are sustainable and privately financed.
The good news is that the Florida East Coast (FEC) does operate a short-haul service between Miami and the Atlanta market (in interchange with Norfolk Southern). That appears to be the most successful current short-haul intermodal operation during the 2000 to 2019 period. But note: It’s not being widely adopted by other railroads. And previous sprint-like short-distance routes along the Chicago-St Louis and Chicago-Minneapolis lanes were tested. But they were then shut down. The Canadian Pacific Railway TOFC trailer-focused market in eastern Canada was also tested, but as the trainset equipment aged, it too was shut down (in the summer of 2018). The conclusion is that whatever its profit margin, it didn’t fit with today’s often investor-centric business return expectations.
Market View Conclusions
The short-distance deal killer aspects of rail intermodal center on the following business fundamentals:
These don’t add up to an overwhelming intermodal advantage. Something basic is missing. Few shippers or Class I railroads are saying, “I have to get one of these short-haul routes!”
A 2004 analysis offered by Dr. Edward K. Morlok (University of Pennsylvania), showed evidence, by using a regression analysis, that “the drayage cost clearly dominates as a limiting intermodal service factor.” At a haul distance of 200 miles, drayage can be about 75 % of the total rail intermodal cost. At 500 miles, it drops arguably to about two-thirds of the total cost—but is still a large inhibiting factor.
Unfortunately, depending upon market timing, drayage costs can actually be as much as $300 or more per dray movement. That is a really a big wildcard in any supply chain model. Add to these drayage costs some uncertainty of time to dray, time to load, and time that containers might be held for the next departing long train—and the short-haul intermodal model is risky.
Intermodal often has too many organizers and “doers” involved. Complexity breeds uncertainty. Coordination among multiple players is more complex than is a direct single truck origin-to-destination movement.
Upside? Yes, there are possible solutions. But short-haul intermodal is mostly still a working theory as we begin 2020.
