The average age of a diesel powered locomotive in Europe is well over 30 years old, but in fact, many are much older. What other major industry, that is vital to the prosperity of a nation, operates equipment this old? It is commonly done in the railway industry. This begs the question: Why?
The answer, most often, is cost. The price of a new locomotive is several million dollars or euros. Although there are significant benefits to a newer locomotive, they don’t always outweigh the cost savings of modernization. Getting the many benefits and advantages of new locomotives, with your older fleet, is not only possible, but proven and cost effective. For as little as a few thousand dollars, you can realize significant and measureable improvements. The goal is to implement a majority of the benefits of a new locomotive on your existing fleet, but keeping cost to a minimum.
The simple diagram shows how renewing your locomotive can offer many of the benefits of a new locomotive at a fraction of the cost. So what are these benefits we are searching for?
With the volatile fluctuation in diesel fuel costs and the sheer volume of fuel use by locomotives, this is often the most significant cost for a railway. Aging locomotives, 20 years or older, are less efficient than newer locomotives, even if the engines are well-maintained. A 1,000 horsepower (750 kW) yard locomotive will burn over 10 liters of fuel per hour of idling. Typically, an active locomotive in a yard idles over 50% of its day. If the locomotive works 12 hours/day, 5 days per week, this can amount to over 15,000 liters consumed due to unnecessary idling. Technology exists that can significantly reduce, if not eliminate, this unnecessary idling and can provide significant returns on investment through fuel savings.
Older locomotives create a disproportionate amount of pollutants. Specifically NOx, HC’s, POC’s, CO and GHG’s. Reducing unnecessary idling will also reduce these emissions. Older locomotives may have lead in their electrical circuits. Modernizing the control system can eliminate many of these components.
Locomotives equipped with non-microprocessor based control systems usually do not operate the locomotive at its full potential. Upgrading the control system can maximize the horsepower as well as the tractive effort or pulling power of the locomotive. Additionally, application specific control systems can be used to improve starting efficiency and performance.
Many components on your aging locomotive are wearing out or failing with higher frequency. Some are now obsolete, difficult or expensive to obtain. A locomotive modernization expert can replace them with rugged, readily available hardware. Renewing all, or even just portions of your control system, can significantly improve the reliability and at the same time, reduce the complexity of your locomotive control. An additional benefit is that many of the expensive and large sub component systems on your locomotive, such as the engine, batteries, generators and traction motors, can now be controlled to operate within optimal and/or safe guidelines such as temperature, horsepower, volts and amperage. The result is that not only is your control system more reliable, but the major expensive sub-components are now also more reliable and require less maintenance.
Intelligent control systems provide several levels of enhanced diagnostics, so that faults or service issues can be more quickly resolved. Upgrading the control system on your locomotive gives you the opportunity to monitor vital parameters and to collect data, report and display the performance potential of the locomotive and execute intelligent diagnostics. This can be made available with on-board operator interfaces to both the driver and to maintenance personnel. Further enhancing this with remote connectivity allows targeted personnel to have the right tools to improve the whole railroad’s efficiency through mobile fleet reports and individual locomotive performance information.
HOW can we achieve these benefits?
At ZTR Control Systems, we know locomotives. We are a full service provider, delivering locomotive system engineering, integration and monitoring. We evaluate the performance of your locomotive and identify how it can be improved, to maintain its value in your fleet. Then we design hardware and develop the software to deliver solutions to problems hindering your railway from being as efficient as possible. Beyond the locomotive, we provide remote communication that connects your locomotive to your office and to your people in the field. We offer round the clock technical support and project management, both from our operation center and, if needed, in the field. Some of our key solutions in locomotive modernization are listed below.
Intelligent Starting Technology + Fuel Savings
The ZTR Intelligent Starting Technologies™ improve locomotive performance through easier, more reliable starts and increased fuel savings.
