Wayside Condition Monitoring Technologies for Railway Systems

JVTC

Sammanfattning:
The railway is an important mode of transport, due to its environmental friendliness, high safety level, and low energy consumption, among other reasons. Railways provide a sustainable means of transporting a large amount of freight and passengers, in a cost-effectiveand comfortable way. The railway system has a large number of stakeholders and a small improvement in the system will give many advantages, including financial savings and an increase in the quality of service. The Swedish railway network is old and there has been
almost no expansion of the network during the past few decades. There is currently a demand
for more track capacity and there are no more tracks availably at the network; therefore, the
existing network is expected to deliver more capacity.
The railway operators are the largest cause of train delays and wheel failures are one major
contributor of the delays caused by operators. The infrastructure manager is the second largest
owner of train delays, and a large contributor of their train delays is switches and crossings
(S&Cs).
This thesis shows proposals for how condition monitoring technology can be used more
efficiently for both the infrastructure and the rolling stock to increase the reliability of their
critical items by decreasing train delay.
