Railroad
This industry comprises establishments primarily engaged in one or more of the following: (1) manufacturing and/or rebuilding locomotives, locomotive frames and parts; (2) manufacturing railroad, street, and rapid transit cars and car equipment for operation on rails for freight and passenger service; and (3) manufacturing rail layers, ballast distributors, rail tamping equipment and other railway track maintenance equipment.

NVIDIA Scores 23 World Records for Route Optimization
Kawasaki Heavy Industries is a manufacturing company that’s been building large machinery for more than a hundred years. The Japanese company partnered with Slalom and used cuOpt to create routing efficiencies for the development of its AI-driven Kawasaki Track Maintenance Platform.
Companies can embed cuOpt into the advanced 3D tools, applications and USD-based workflows they develop with NVIDIA Omniverse, a software platform for developing and deploying advanced 3D applications and pipelines based on OpenUSD. Implemented together, cuOpt, Omniverse and NVIDIA Metropolis for Factories can help optimize and create safe environments in logistics-heavy facilities that rely on complex automation, precise material flow and human-robot interaction, such as automotive factories, semiconductor fabs and warehouses.

Parallel Systems Tests Railcar ‘Platooning’ in California
The individually powered railcars are designed to transport standard shipping containers as a single or double-stacked load in short-haul freight operations, and can form “platoons” of up to 50 cars, according to Parallel Systems. “The fully automated platooning process eliminates the requirement for railcars to couple to each other and connect air brake lines,” the company explained. “Upon contact, each vehicle maintains bumper contact with the one in front by controlling tractive effort. The small air gap between containers and the pushing action through railcar bumpers reduces average aerodynamic drag of the platoon, ultimately improving energy efficiency. Individual railcars can also separate from one another, enabling them to bypass rail classification yards and independently proceed to varied destinations, or to keep railroad crossings clear. Brake systems are self-contained in each railcar and therefore do not require connecting air lines.”
How a Railroad Outsider Aims to Improve Service
Precision scheduling “was heavily indexed toward controlling costs and improved asset utilization and, in many ways, didn’t prioritize improving the employee experience and improving customer service,” Mr. Hinrichs said.
The appointment of a railroad outsider to run CSX was a surprise to some investors, after recent bosses such as the late Hunter Harrison—a champion of precision railroading—and industry veteran Jim Foote. Mr. Hinrichs spent 30 years in the automotive industry, including time working at Ford Motor Co. and General Motors Co.
I think our railroad is running the best it’s ever run because we’re engaging with our workforce. We’re solving paid sick leave, attendance policy issues or other things, and I think they go hand in hand. We’re getting the service to our customers because our employees know we’re listening to them.
Rail Giant Alstom Turns to Nexa3D’s NXE 400Pro to 3D Print Replacement Footrests
Alstom, one of the largest railway companies in the world, faced trouble with finding replacement parts first hand when outdated footrests threatened to sideline many of its fleets. The company needed a way to fix its trains quickly, and do so in a cost effective manner. Alstom’s solution? 3D printing. The business sought Lorenzo Gasparoni, its 3D printing and 3D scanning product leader in Italy, to establish additive manufacturing (AM) practices to help keep its aging trains operational while reducing the time needed to service the carriages.
Alstom is no stranger to 3D printing and had previously partnered with BASF Replique and Stratasys to use AM to solve sourcing issues in the past. This time, however, it wanted to stay internal to its manufacturing and service center in Sesto San Giovanni, Italy, and needed Lorenzo Gasparoni for the job. The two have been in working together since 2019, but, in mid-2022, a new project arose: the use of 3D printing to produce hundreds of footrests to replace older counterparts.
Autonomous battery-powered rail cars could steal shipments from truckers
Parallel Systems has emerged from stealth mode with a prototype vehicle that promises to bring advances in autonomy and battery technology to the relatively staid world of freight railroads. In the process, they hope to not just electrify existing routes but also bring freight rail service to places that don’t have it today.
Whether their bet pays off will hinge on whether freight railroads and their customers will buy into a new way of operating. Parallel Systems isn’t just taking an existing freight train and swapping its diesel-electric locomotive for a battery version. Instead, it’s taking the traction motors and distributing them to every car on the train. It’s how many electric passenger trains operate, but it’s a system that has been slow to migrate to the freight world.
This is why railway communications needs great network design
A solid network design is the foundation to deliver on stringent performance requirements associated with mission-critical railway communications and to deliver on consumer expectations, which remain unchanged regardless of being at home or sitting on a train moving at 500km/h.
Network design has the potential to identify the optimal site locations to deliver the target performance at the best TCO, but its complexity cannot be overlooked. While cell planning tools exist, operating them for the right outcome is not trivial and requires highly skilled experts connected to a global knowledge base to keep up to date with the latest industry developments and realize the potential of 5G-based FRMCS.
How did one of the world's largest robots end up here?
The autonomous train, consisting of three locomotives and carrying around 28,000 tonnes of iron ore, travelled over 280 kilometres from our mining operations in Tom Price to the port of Cape Lambert. It was monitored remotely by operators from our Operations Centre in Perth more than 1,500 kilometres away. Our AutoHaul™ team at the Operations Centre in Perth continued to hone the technology, running thousands of hours of tests. The AutoHaul™ project was made fully operational in June 2019, making it the world’s first fully autonomous, long distance, heavy-haul rail network.
“The time-saving benefit is enormous because the train network is a core part of the mining operation. If we can prevent those stoppages, we can keep the network ticking over, allowing more ore to be transported to the ports and shipped off more efficiently,” says Lido. “The other major benefit is safety,” he continues. “We are removing the need to transport drivers 1.5 million kilometres each year to and from trains as they change their shift. This high-risk activity is something that driverless trains will largely reduce.”
