By Dr. F.A. Wingler, June 2020 with UPDATE November 2021 With the partition of 1947 India has lost the direct access to the Kashmir Region. 1994, the Railway Minister declared the need for a rail line to Baramulla, well beyond even Srinagar. This Jammu–Baramulla Railway Line had been planned to connect the Kashmir Valley in […]

QUO VADIS? COMPETITION BETWEEN BOLTED,SCREWED CLAMP & DRIVEN SELF-TENSIONING CLIP RAIL FASTENENINGS By F.A Wingler, October 2021

The technical paper deals with the two principal categories of ELASTIC Rail FASTENING or RAIL FIXATION SYSTEMS, which we find on railways around the globe: Bolted or screwed Clamp Systems, where the Clamping or Down-Hold Force is generated by tensioning a Clamp through applying a torque on a quenching screw bolt; so-called “Threaded Clamp Systems”. […]

Ribbed Base-Plate Rail Fastenings in Pictures By F.A. Wingler, March 2001

The bearing ribbed base-plate for rail fastenings had been designed in Germany by the engineer Döhlert and introduced on German Railway in 1926. It is the most successful base-plate for indirect rail fastenings on wooden-, steel-, concrete-, composite-, polymer sleepers and ballast-less slab tracks around the globe. The KPO fastening from 1926 on wooden sleepers […]

Advanced Rail Fastenings in India By Dr. F. A. Wingler, February 2021

With advanced Turnouts, Metro Rail, Ballast-less Rail Tracks, Regional Rapid Transits and High-Speed Line new impetus has been given to the Indian rail fasting market and applications. The spectrum of advanced rail fastening assemblies has become wider. The promotion of indigenous manufacture of advanced rail fastening components under “Make in India” will give an impetus […]

Characterisation of self-tensioning elastic Rail Clips, ERC, of PANDROL Type By F. A. Wingler, February 2021

Rail Fastening on concrete sleepers with the RDSO designed MARK III Elastic Rail Clip, ERC, has become standard in India. The self-tensioning or self-stressing elastic Pandrol-type rail clips are manufactured by giving a spatial bend to Silicon-Manganese alloy spring-steel rods. Their advantage is the simple installation parallel to the rail. The ERCs are pushed with […]

Flash-Butt welded Long Rolled Rails, LRR, of Prime Steel Quality help to lower the Risk of fatal Train Accidents in India By F.A.Wingler, January 2021

Long Rolled Rails, LRR, of prime steel quality, already tested in the manufacturing plant, and with Flash-Butt Welds of higher strength than that of Alumino Thermic, AT, welds, provide far better alignment and continuity parameters with less alignment perturbations for far smoother train runs with less dynamic response of rail vehicles, that lower the risk […]

METRO/TRAM-TRAINS The Multi-Talents

Metro/Tram-Trains are Multi-Talents or Chameleons, that operate locally on the City Rail Networks and as well inter-regional or between cities on Main-Line Railway networks, bringing commuters from one City Center to the next City Center without changing the transport mode. Metro/Tram-Trains operate seamless with one-and-the-same Rail Vehicle on Lines of Metros, Subways, Street Cars, Street […]
