FreightWeekSTL 2022 kicked off May 23 with Innovation Day, featuring emerging technologies that have the potential to dramatically change the future movement of freight. The opening session highlighted the advancements being made by St. Louis start-up Intramotev Autonomous Rail. Those in attendance learned about an autonomous, zero-emissions railcar that would be able to operate without the use of a locomotive. That new technology could enable better use of the U.S. freight rail network and help mitigate the type of supply chain challenges occurring around the globe, while reducing pollution in the rail industry.
Timothy Luchini, Ph.D., CEO and co-founder of Intramotev, commented on the trends related to the movement of freight by rail and truck, with year-over-year increases in trucking volumes and flat or slightly decreasing volumes in rail. He said these are trends his company hopes to reverse with its new autonomous vehicles as they build the technology they believe will help make railroads competitive for the next 200 years.
“The world is continuing to push towards just-in-time delivery of just what you need when you need it to be there. And you're seeing it with everything,” Luchini said. “You’re forced with this dichotomy between trucking and rail, where rail is your low-cost solution and trucking is what offers speed and flexibility. And that's a lot of tension on most supply chains. We think that what's needed is something new that builds on all these industry trends that you see with autonomous trucking on the forefront and electrification of trucking in conversations everywhere. But rail has an opportunity here to build something that is more competitive than those solutions, and build on top of the strengths of the rail infrastructure that runs across this country.”

Intramotev is building that “something” that could be a game changer for the rail industry – the TugVolt. This is a battery-electric, self-propelled railcar that enables freight to move with the flexibility of a truck, without breaking the existing model of rail operations. The concept allows for the vehicle to be in first and last-mile service and create a form factor that can be as fast and flexible as a truck. In the middle-mile operations – where Class I railroads are efficient today with very long trains – it still has all the required safety systems to serve as a railcar during those legs of the journey. In short, it provides a solution that complements the current model of rail transportation by allowing for the packetization of freight and vehicles, yet offers speed and reliability.
Luchini said a vehicle like this can also help solve dwell issues -- the time that is required for vehicle delays, when they are waiting to get moved. Congestion at major ports in the United States is another challenge TugVolt is working to address. This type of railcar solution allows for better utilization of existing vehicles by shortening the size of the train, the number of cars in the consist – reducing congestion in a way that allows materials to get moving again.
From a technology perspective, Luchini said the TugVolt contains three containerized modules, including a sensory and location stack that identifies a vehicle’s location, how fast it is going and what is going on around it; an energy storage module, and a propulsion drivetrain with regenerative breaking.
“It’s really important to set the perspective for what battery technology is capable of today. It helps to reduce the individual vehicle cost while carrying the right types of volumes for long ranges.”
The TugVolt has battery packs that are smaller and more in order and magnitude of an electric car because of rail rolling resistances and aerodynamic drag benefits. There is the ability to shrink those pack sizes down and stack efficiencies on top of each other to provide vehicles with 100 to 600 miles of range with 100-ton types of payloads without sacrificing burden payloads because the rail capacity can handle so much more load. It affords the opportunity to right-size the energy storage to the mission and use energy storage and battery technologies that are available off the shelf today, whereas certain other solutions and mobility sectors still need two-times or four-times improvements in energy storage to close business cases. Rail also allows for vehicle platooning, inherently enabling vehicles to be built to handle and share loads between the vehicles in the consist, giving opportunity for energy sharing and a more efficient utilization of those battery packs distributed along multiple vehicles and multiple systems along the length of the train.
Luchini also talked about how the Intramotev technology is addressing environmental impacts. “Any movement of trucking volume to rail is immediately environmentally beneficial. Trucking in general is going to emit nine times more greenhouse gases per ton-mile of transportation than rail. In order for rail to really be able to do that and to take some of that market share and volume, they have to be offering something that's competitive with what trucking is offering. TugVolts can still take advantage of the efficiencies of rail, and are the right type of path ahead. Ultimately, you get all these other ancillary benefits of getting trucks off the road, reducing congestion and improving traffic safety that come with the adoption of a vehicle like this.”
In terms of how soon and where the TugVolt will be making its official debut, Luchini said Intramotev has early pilots in private and captive-use cases scheduled for the end of 2022. Examples of such private captive use cases could be a river port or transload facility connected to a processing facility that might be a few miles inland, and the TugVolt would be tested during a variety of operations. He also cited interplant railroads at operations such as steel mills where rail moves around facilities, and even connecting point to point inside the same factory, as scenarios where this could be a really useful, viable technology. Deployment like this will provide an opportunity to collect all the data that shows it is operating safely and reliably, and that will enable Intramotev to then test in the larger rail networks. Getting to that stage will also require working through the regulatory environment and that process will take time.
Mary Lamie, Executive Vice President of Multi Modal Enterprises for Bi-State Development and head of the St. Louis Regional Freightway, moderated the conversation with Luchini. “The U.S. rail freight network spans roughly 140,000 miles according to the Federal Rail Administration,” Lamie said. “It's clear from today's discussion with Tim that he and his colleagues at Intramotev are seeing tremendous opportunities to use this new autonomous rail car to expedite the supply chain process in the short term, and ultimately to unlock the full potential of the U.S. rail system to take better advantage of its massive reach.”
FreightWeekSTL 2022 wrapped up on May 27 and featured panel sessions with industry experts and leaders in freight, logistics and transportation.
