The paper deals with the possibility of installing a double-circuit Gas Insulated transmission Line (GIL) in the pilot tunnel of the new planned railway galleries Fortezza-Innsbruck. The high GIL power ratings with very low power losses would allow a strong and highly efficient energy exchange particularly useful for the future European Market and could represent a new fundamental step in recon...

after 1860’s the railway systems has started to be used in urban transportation in the world. however, especially after the 1950’s, automobile usage has been increased quickly. thus the dense of transportation has started to move from railway systems to the ones with rubber tire vehicles in istanbul. traffic density in urban transportation has started to be experienced since 1950 with the incre...

The location of ground faults in railway electric lines in 2 × 5 kV railway power supply systems is a difficult task. In both 1 × 25 kV and transmission power systems it is common practice to use distance protection relays to clear ground faults and localize their positions. However, in the particular case of this 2 × 25 kV system, due to the widespread use of autotransformers, the relation bet...

It is widely known that the railroad diesel locomotive engines emit significant amount of air pollutants. However, these engines are not equipped with any air pollutants reducing devices in Korea, resulting in the accumulative air pollution near the railroad. Because the pollutants emission from driving locomotive engines cannot be measured directly, the emission factors based on the amount of ...
