Railway track data include massive data sets, unstructured data, heterogeneous databases, information in the form of images, and streaming, noisy and missing data. Railway track engineering problems can be classified into two groups: forward problems and inverse problems. The wheel‐rail contacts determine in part the reliability of railway.
Big data is one of the term named for this large and different type of data. Due to its extraordinary scale, privacy and security is one of the critical challenge of big data.
