Fast approach to calculate the ballastless track impedance

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2018
Purpose The track impedance is one of the most important parameters in designing the track circuit which is widely used in the railway signal control system to detect the presence of a train. This paper aims to calculate the ballastless track impedance by taking account of the influence of reinforcement bars.

Ballasted Track versus Ballastless Track

Key Engineering Materials, 2015
First concrete sleepers were made of normal reinforced concrete and used during the 1930s and 1940s. Concrete railroad ties became popular in Europe after World War II because of the advances in design, material quality and production of pre-stressed concrete. Now as before, concrete sleepers on ballast represent the primary basis of track construction,
