Yapi Merkezi / Yapiray

 

Since end of 2014 Coenraad Esveld is adviser to Yapi Merkezi / Yapiray for track related problems. In may a 2 days meeting in Istanbul took place to discuss a broad spectrum of subjects such as slabtrack, track maintenance, quality aspects, innovative track maintenance methods, various track related software, increase of axle loads and the impact on design and maintenance and various actual projects.

Digital Version of Modern Railway Track

 

The Digital version of Modern Railway Track has been released in pdf format and can be ordered via http://www.lulu.com/spotlight/esveld. The price is € 50.

I am presently working on an ePub and a mobi version for publication via the Apple Store and Amazon respectively.

 

After more than 10 years, and with the upcoming digital techniques, it is the right time to publish a digital version. The present edition MRT-3 is in fact a digital copy of the original Second edition, with all errata corrected and with some minor updates.

It is intended to update the book in the next couple of years to the actual state of technology, with emphasis on weld treatment and slab track. But also contact mechanics, track components and the new EN standards will be treated. That digital version will be published as MRT-4

For suggestions on improvements or enhancements please contact me at coenraad@esveld.com.

 

At www.esveld.com under ‘Downloads’ and then ‘Additional Downloads’ you can find pdf files of my lectures, conference presentations and a basic railway course in Dutch.

Visit of Yapi Merkezi
On 16 March 2012 chairman of Yapi Merkezi Dr Ersin Arioglu visited Dr. Esveld to discuss a number of items concerning the Turkish high-speed line between Ankara and Konya. The meeting was held at the office of ALOM (Mr. Edwin Aerts). In the discussion on quality control the new welding standards used at ProRail were extensively discussed and Mr. Ruud van Bezooijen, one of the principle advisors to ProRail for rail and welding issues, demonstrated the RAILPROF measuring device and explained how the measurements are used in practice.

Seminar on Noise and Vibration

 

On 28 June 2011 a seminar on Noise and Vibration was held in Ankara, Turkey, hosted by TCDD in cooperation with ALOM, LINK and Amorim. After some background on the theory and the principles applicable for vibration reduction and mitigating measures, various practical solutions were presented and discussed. Under Sleeper Pads (USP) were considered as one of the most cost-effective measures for reducing vibration propagation. The principle is based on lowering the natural frequency and this requires a relatively large mass on a soft spring. A natural frequency of 20 Hz, above which vibrations will be reduced, should be considered as the maximum achievable for this kind of solutions. Furthermore, softer rail pads will have a positive effect on confining the transmission of forces in the higher frequencies and thus will enhance the life cycle of the track structure. But also the short wave irregularities in the rail running surface and the wheel running surface should be controlled, as they are the primary source for generating high frequency force excitations. For this reason, it was emphasized that quality control and monitoring is of prime importance. In this context Dr. Esveld presented the new force-based weld geometry standards used by ProRail in The Netherlands and the RAILPROF measuring device.

Cooperation with ALOM

 

On 2 May 2011 Coenraad Esveld and Edwin Aerts, Director of ALOM BV in Arkel, The Netherlands, signed an agreement for cooperation. ALOM is a supplier of track components, such as rail pads, fastening systems and sleepers. An important focus is polyurethane and crock rubber for application in high speed rail and for noise and vibration mitigation solutions.

Japanese version of Modern Railway Track released

 

Preface to the Japanese edition of Modern Railway Track

 

The first edition of Modern Railway Track, published in 1989, was translated into Japanese by my colleague and friend Dr. Yoshihiko Sato in 1993. It was also Dr. Sato who provided the necessary input on Japanese track technology and practice for the second edition.

 

Nowadays an important focus is on high-speed track technology, as high-speed networks are expanding rapidly, especially in Asia and Europe. Japan was the initiator and pioneer of high-speed technology, later followed by France and other European countries. Although the French network mainly comprises of traditional ballasted track, Japan strongly focused on slab track, with the well-known and successful J-Slab. Studies on life cycle cost and availability have shown the great potential of non-ballasted tracks and their great advantages of maintenance reduction. This has now emerged to large scale slab track applications worldwide, with Shinkansen J-Slab and the German Rheda2000 as the leading solutions.

 

It was a great honor and pleasure when I received the letter of Mr. Toshihiko Kunihiro, General Manager Track & Structures Department of the West Japanese Railway Company, to ask my approval for the translation of Modern Railway Track – Second Edition – into Japanese, which I of course readily accepted. It was Dr. Kenzo Tokuoda, former Senior Executive Managing Director of JR-West and a highly respected railway engineer, who carried out the tedious translation job. I would like to express my great appreciation to him for his dedicated work, making my book more accessible to the Japanese railway community.

Seminar on high-speed lines in Asia and Europe at the Technical University of Madrid
This seminar was organized by the University of Madrid, on the initiative of Prof. Manuel Melis. For program click here. There were contributions from China Prof H. Xia and Prof W. Zhai), Korea (Dr. K. In-Jae), Taiwan (Prof. T.C. Kao), Germany (Prof. Stephan Freudenstein) and The Netherlands (Prof. Coenraad Esveld). It was quite impressive to hear about the progress in China, where by the end of 2011 the high-speed route length will be about 13,000 km, which will be increased in 2020 to around 30,000 km. In the next 5 years China will invest € 400 billion in railways. The long term route length for high-speed lines in Spain is in the order of 3,500 km, Japan 2,500 km, France 2,000 km and Germany 1,400 km.

 

      

 

Beijing-Shanghai 1,318 km, 80 % bridges, Vmax = 380 km/h, travel time 4 hours, 230 trains per day, 160 million passengers/year.

New software release for RAILPROF PDA

A new version of the RAILPROF PDA software is released with the following new features: built-in ftp client for wireless transfer of measurement files. The files are stored on the ftp server in the directory \\Job\Welder. At any time the welder can push the button ‘Send FTP’ to send all the measuring files not yet transmitted. A copy of the files remains on the SD card of the PDA. Furthermore, additional speed classes have been added, especially in the lower speed range for metro and tram applications. The third point is that the RAILPROF will be kept awake as long as the operator is working in the measuring menu on the PDA. Normally the RAILPROF is switches off after 10 minutes of not being used.

Visit of SMT-Railway (Nippon Steel)
A delegation of Sumitomo Metal Technology, Japan, was in Holland to discuss cooperation for distributing the RAILPROF in Japan. Pictures were taken at De Rooy Slijpbedrijf in Nuenen, where tests were carried out with the RAILPROF on precision ground and measured rail pieces. The precision measurements were done with a Mitutoyo 3D Coordinates measuring machine.

Some Aspects of Track Design by Coenraad Esveld

Site Visit and Advice to Mumbai Railways and Seminar on New Technologies
Advised on maintenance issues and decision support systems for a World Bank project lead by MerMec, Italy. It was quite impressive to experience that both Central Railways and Western Railways carry 60 MGT per annum for passenger traffic. In the Netherlands the average figure is less than 10 % of this value. The possibilities for carrying out track maintenance are very restricted due to possession time and track access conditions.
New maintenance and inspection technologies were presented by Professor Coenraad Esveld in a seminar held on 26 November, with amongst others the following topics:

     Impact of rail and wheel surface problems;

     Grinding technology;

     Importance of resilience. Use of USP (under sleeper pads) and more resilient polyurethane rail pads;

     New weld geometry standards developed by Delft University of Technology for ProRail;

     Demo of WeldRegister Pocket PC for the wireless transmission of inspection data and RAILPROF measuring files and the use of the WeldRegister Access database.
