Working it out in Logs

Railway safety management is a complex subject that involves a significant amount of manual intervention in the assessment, analysis and control of risk. Supporting documentation is, usually, worked on by multiple parties, with differences in system viewpoints and writing styles. Maintaining quality safety documentation is therefore an interesting challenge for the industry. Hazard logs, for example, play a central role in both system engineering and...

Shedding Light on Train Delays

Degradations in on-time performance of Britain’s trains cost the rail industry over £100 million a year. However, the additional cost to the economy in lost time is over £1 billion [1]. On-time performance is directly impacted by a multitude of events including train reliability, poor track quality, and operation under degraded conditions. To better understand what constitutes the major contributions to delays, the rail industry...

Hornby BIG DATA Project

Overall Purpose of the Role: There is a big push to make railways more effective and increase capacity. The main opportunity is to run trains closer together and autonomously. We are building a model railway that can be used to explore possibilities for this. The main theme will be to use an existing model railway set-up that already has digital control. See the set up...

Will a data driven approach replace RAMS and conventional safety engineering?

If one looks through the railway safety and reliability standards, EN50126 / EN51028/9 https://www.linkedin.com/groups/4985242 and the recommended activity at each life-cycle stage it will be seen that nearly all the items are data driven. Using Big Data and Machine Learning we could eliminate a lot of the work done now by safety engineers. Of course you would have to follow a more formal system engineering...
