Railway Maintenance Must Become Smarter

22.11.2004


One of the conclusions of Arjen Zoeteman, who will defend his thesis on 22 November at TU Delft, is that significant amounts of money could be saved on the maintenance of European railway systems, including the Netherlands. Through a carefully structured schedule and a detailed analysis of maintenance work, he was able to achieve a cost reduction of 10 percent for the Dutch railway system.



The operators of the rail networks, such as NS, are continuously increasing the demands on the administrators, such as Prorail (in the Netherlands). The type of maintenance work is therefore shifting from craftsmanship based on individual knowledge to an engineering discipline in which quantitative calculations play an important role. According to Zoeteman, most European railway administrators fall short in their analysis and scheduling of maintenance. This shows in, among other things, the lack of detailed information systems for the analysis of maintenance performance. Another aspect that Zoeteman states should be strongly developed is a ‘life-cycle’ way of thinking, in which long term cost-effectiveness is taken into account.

One of the underlying problems, according to Zoeteman, is the division of the maintenance work into separate disciplines and maintenance regions (the Netherlands, for example, has four regions). At the moment, budgets are generally granted based on requests that come from the ‘bottom up’, in other words, from the various disciplines and regions. Zoeteman thinks that a centrally managed process of quality guarantee, based on an overview of the total situation will deliver better results.


Zoeteman has tested his ideas for improvement in a number of practical situations. One of those was a study conducted at Prorail. The goal was to, for the first time, come up with a number of national guidelines for railway system renewal. The project resulted in a predicted saving of 10 percent in the costs of the renewal of the superstructure. Based on his research, Zoeteman is going to work with Prorail on a damage catalogue for large scale maintenance and renewal. Eventually this could be used in a so-called Decision Support System (DSS). A DSS is a computer system that assists administrators in making the best choices for a particular purpose, in this case the upkeep of the railway system.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
