Sorry if this is wrong board, i really dont know where to post this

Im about to start work in a place that has an element of transport in it, mainly that we are working in the near vicinity of train tracks. Every now and then a person/a customer might unalive themselves by throwing themselves in front of a coming train. This is considered something that the worker must deal with (the internal psychic dealings that come with witnessing something like that)

Im just wondering, are there people who have experience in jobs like this? What have the situations been like, and would you characterize them as traumatic, to yourself or others? Im just trying to get a feel of what the potential situations that might come across can be like
