In the country of Attaga *, you have been employed as a railway specialist, to advise the local railway company on monitoring and maintenance issues. This country has a dense rail network with a total of over 20.000km of railway tracks. These tracks span the whole country, from the small islands, through the coastal cities, the delta, and the mountains, up to the desert. About 1/3 of the network consists of high-speed trains, connecting the main cities. Another 1/3 consists of heavy use middle long-distance commuter tracks, connecting cities, and nearby villages. The last 1/3 consists of tracks connecting the remote villages and has a relatively low frequency of usage. During one of your working days, suddenly you receive the following 4 warnings about the system. Warning 1: high continuous vibrations have been measured on one axle of the train. Warning 2: the presence of multiple cracks has been detected in the rail in a curve. There is no information available yet about their severity. Warning 3: irregularities in the track geometry have been detected at the transition from ballasted track to the track on a steel bridge. Warning 4: increased track vibrations have been measured around a rail weld on a steel bridge. Luckily you are working as part of a larger team thus for now you can focus on only one of these issues. Pick one of the issues and answer the following questions about it (while keeping in mind the essences of the network in this country): Please find attached template to complete.
