[China Instrument Network Instrument Development] Track wear will reduce train safety and increase fuel costs. Researchers at Tomsk Institute of Technology in Russia have developed a highly accurate alternative to manually measuring the degree of wear on railway rails. .
According to developers, the most common method for measuring rail wear is to manually measure with movable brackets, calipers, and stencils. On a busy railway line, it is measured by a special train equipped with an automatic system, but this method is too expensive and can only be used on large trunk lines. Newly developed devices are mainly used on those railways that are still using manual inspections.
The device is a metal structure. When it is used, it is fixed on the track. The laser sensor is used to measure the distance from the track to the orbit surface at 300 points at a time, so that high-precision data can be obtained. The measurement process takes only about 5 seconds. In addition, the researchers also developed a supporting mobile phone application software. Based on the measured data, the outline of the track was displayed on a smartphone and compared with national standards.
At present, Tomsk University of Technology has produced test prototypes. Staff at the Electronics and Automation Equipment Department are improving their mechanical components and studying more accurate mathematical algorithms.

Sack Gabion
Sack gabion is
cylindrical basket made of 8x10 double twisted steel woven wire mesh,
with mechanical characteristics higher than the ones suggested from EN
10223-3. It's filled with stones at the project site to form flexible
and permeable structures used for emergency and river training works
where local conditions require fast installation or where the water does
not allow for easy access to the site and where underwater installation
is necessary.
Sack gabions are
supplied with steel reinforcing wires inserted during the manufacturing
process to facilitate closing during installation. The wire used for
the manufacture of gabion shall have a tensile strength between 3
80-550N/mm2 exceeding, in order to increase the tensile resistance of
the finished products, what is suggested from EN10223-3. Wire tolerances
are in accordance with EN 10218. Elongation shall not be less than 10%,
according to EN 10223-3. Test must be carried out on a sample at least
25 cm long. Meantime the adhesion of the zinc coating to the wire shall
be such that, when the wire is wrapped six turns around a mandrel having
four times the diameter of the wire, it does not flake or crack when
rubbing it with the bare fingers.
