Abstract
We propose a parameter estimation approach to fault diagnosis for jointless track circuits in railway transportation, focusing on the compensation capacitors. How to estimate various parameters of the jointless track circuits poses a tremendous challenge, because the existing track circuits do not have sensor networks embedded to the railway network. Assuming the available special inspection train and the measurement data, we analyze how various parameters of the jointless track circuits can be estimated, and how faults in the compensation capacitors can be detected. Our analysis results are illustrated by a numerical example.
