Progress Rail offers an integrated portfolio of fuel management technologies. By combining automation, analytics and real-time monitoring, the company aims to help operators optimize fuel usage across locomotives, yards and entire rail networks, Progress Rail officials said in an email.
The Talos™ Energy Management and Train Automation System applies machine learning and high-performance computing to optimize train handling in real time. Talos continuously analyzes route profiles, train dynamics and operating conditions to determine the most efficient throttle, braking and speed strategies, delivering measurable fuel savings while also reducing emissions and improving train handling consistency, company officials said.
PR Uptime IQ™ is an IoT-enabled, cloud-based platform that shifts fuel and maintenance strategies from reactive to predictive. By leveraging real-time locomotive data and advanced analytics through Uptime IQ, railroads can gain insights into train performance, territorial inefficiencies and operating behaviors that impact fuel usage.
Uptime IQ’s analytics engine also detects fuel-system patterns, providing railroads early visibility into conditions that might require proactive attention. The actionable information enables railroads to address inefficiencies quickly by adjusting train builds, strategically improving infrastructure, tightening dispatching practices and providing fast constructive feedback to operators, company officials said. Advanced analytics detect atypical fuel-system patterns, enabling proactive intervention.
Additional tools such as Automatic Engine Start/Stop (AESS™) and fuel monitoring within the PowerView™ Suite are designed to further reduce fuel waste by limiting non-productive engine run time and improving operational visibility.
Wabtec’s Trip Optimizer™ (TO) provides proven, repeatable fuel savings across a wide range of operating environments, company officials said.
TO functions as a smart cruise control system for trains, accounting for terrain, train makeup, speed restrictions and operating conditions to continuously optimize performance. As trains have become longer and more complex, TO has evolved to manage some of the industry’s most demanding consists, including manifest trains exceeding 300 rail cars and 35,000 tons.
Advanced capabilities such as Smart Horsepower Per Ton (HPT) help optimize power distribution across the consist by using only the locomotives required to maintain target speed. TO is EPA-certified to deliver up to 10% fuel savings, with Smart HPT certified for an additional 5%. When integrated with LOCOTROL® Distributed Power, certified configurations can qualify for up to 17.2% in EPA emissions credits, company officials said.
Network level efficiency also can improve through Movement Planner–Pacing, which is designed to enhance coordination between dispatch planning and onboard train control. By adjusting speeds to reduce excessive dwell at meet points, pacing typically delivers 2% to 4% fuel savings per dispatch region without impacting network velocity, company officials said.
Wabtec is further expanding TO’s operating envelope by integrating air brake control, enabling the system to move trains from a standstill, regulate them to speed limits and engage controlled stops at designated points. Along with continual software enhancements, the capabilities extend TO’s role beyond fuel efficiency, supporting more consistent, intelligent train control as railroads prepare for increasingly complex operating demands, company officials said.
Developed by New York Air Brake, the LEADER® (Locomotive Engineer Assist/Display & Event Recorder) system uses advanced train control algorithms to reduce fuel consumption while mitigating hazardous in-train forces. Operating as the locomotive’s “computational brain,” it transforms traditional train handling through sophisticated control methodologies, company officials said.
As a predictive engine, LEADER constantly analyzes track characteristics, train consist data and current operating parameters to execute high-fidelity, on-board physics simulations. To ensure accuracy, the system combines these predictive simulations with real-time feedback, continuously updating the simulations to adapt to changing conditions.
The software evaluates multiple operating strategies at once to balance the tradeoff between speed and fuel consumption at the network, train or trip level. Calculating multiple options in parallel several miles ahead, the software evaluates multiple operating strategies at once. It dynamically selects the optimal profile, and by commanding throttle and dynamic braking applications, maximizes fuel economy while minimizing draft and buff forces along a train’s couplers, company officials said.
Deployed across multiple locomotive platforms globally, LEADER is the only energy management technology operating fully autonomous train operations, doing so over hundreds of miles without interruption, they said.
Designed to reduce unnecessary fuel burn without sacrificing performance, the U.S. EPA SmartWay-verified PowerHouse™ Hybrid provides a smarter alternative to continuous cold-weather idling, Power Drives Inc. officials said. Rather than consuming 5 to 8 gallons of fuel per hour, the system operates at 0.38 gallons per hour, allowing for more predictable fuel usage and stronger budget control.
Many operators report seasonal savings exceeding 10,000 gallons per locomotive, achieving a return on investment in a few months, company officials said.
The PowerHouse Hybrid is powered directly from the locomotive battery bank for up to seven days without starting the engine, reducing fuel consumption during extended stops. When shore power is available, the system can be plugged in to an external 120 VAC power source to operate while charging the batteries, further optimizing fuel usage and flexibility.
By maintaining engine oil and coolant temperatures above 100 F, the PowerHouse eliminates cold starts and wet stacking, and reduces wear caused by temperature swings, helping prevent unplanned maintenance.
ZTR has installed Automatic Engine Stop-Start (AESS) systems that significantly reduce locomotive idling, adopted starting assists to bolster batteries while starting the engine, and utilized telematics to track fuel savings and utilization, company officials said. As operational demands intensify, more significant gains can be realized with intelligent integration of these technologies, they added.
Take for example the combination of the company’s SmartStart and KickStart solutions. While SmartStart monitors critical parameters to shut down engines safely, its effectiveness has at times been limited by “starting anxiety — the fear of leaving the engine alone to shutdown and restart successfully,” company officials said.
Integrating KickStart and using supercapacitor technology to supplement battery power during engine cranking can reduce voltage drop, lower strain on batteries and improve engine start reliability in all conditions. With a 24% reduction in engine crank time and guaranteed starts in extreme weather, operators can allow AESS logic to maximize shutdown durations, leading to a 55% reduction in idle time waiting for batteries to charge, company officials said. ZTR studies show an additional 10% in fuel savings with KickStart and SmartStart combined.
Hardware alone can save fuel, but ZTR’s remote monitoring platform Vision is designed to ensure savings are sustained and documented. By providing real-time alerts and automated fuel-savings reports, Vision enables fleet managers to monitor how the SmartStart-KickStart duo is performing across the network.
L.B. Foster’s portfolio includes high-performance Gauge Face (GF) lubricants, including all-season SYNCURVE® and KELTRACK® Top of Rail (TOR) water-based friction modifiers. The technologies generate significant, measurable reductions in fuel consumption, company officials said.
Two primary contributors to rail fuel usage are curving resistance and rolling resistance, according to AREMA. Curving resistance arises when locomotives and rail cars navigate curves, while rolling resistance represents the total forces opposing motion that must be overcome by locomotive tractive effort.
Friction management directly addresses both factors. GF lubrication is formulated to reduce drag at the wheel flange–rail gauge interface by lowering excessive friction. TOR friction management further decreases curving resistance by reducing lateral forces and associated flanging forces.
In addition, TOR friction modifier application can optimize rolling resistance by conditioning wheel tread and top-of-rail friction to an intermediate level that balances traction and efficiency.
Since the early 2000s, field studies presented at major technical conferences have consistently documented fuel saving benefits from friction management, with reported reductions typically ranging from 2% to 8%, depending on operating conditions, company officials said.
Recent trials on Shuohang Railroad demonstrated that the implementation of KELTRACK onboard TOR friction modifier spray systems delivered measured energy savings of 6.8%, company officials said. Additionally, trackside-based friction management implementation on a Class I resulted in a measured 4.4% reduction in fuel consumption over a 50-mile segment of medium-curvature track with partial ascending grade, they added.
OptiFuel Systems designs fuel efficiency into the primary energy system rather than layering it on top. By hybridizing power at the platform’s core, OptiFuel changes when and how motive power is generated, used and recovered, company officials said.
The hybrid system incorporates 1.8 MWh battery modules (2,200 horsepower equivalent), which carry the locomotive through idle and low throttle notches, respond dynamically during transient load events and higher notches, and store energy captured through regenerative braking (down to 3 mph). The maintenance-free battery system is rated for about 15 years (about 4,000 cycles) and can be replaced in about an hour, company officials said.
Primary power is provided by Tier-5-ready, 1,400-horsepower internal combustion power modules configurable for diesel, dual-fuel or natural gas operation. The modules also serve as the onboard battery charging system.
This state-of-the-art, engine-generator system maintains operation within its optimal efficiency range, delivering up to 25% lower fuel consumption per horsepower compared to conventional large-format locomotive engines, company officials said.
Under comparable duty cycles, OptiFuel diesel-hybrid locomotives deliver about 40% lower fuel consumption than legacy switcher and line-haul diesel platforms, company officials said. Dual-fuel and natural gas configurations can further improve operating economics by enabling up to 60% fuel-cost savings when lower-cost fuels are available, they added.
