    MockHttpServletRequestBuilder builder = MockMvcRequestBuilders.put(UPDATE_TRAIN_URI)
        .contentType(MediaType.APPLICATION_JSON_VALUE).accept(MediaType.APPLICATION_JSON).characterEncoding("UTF-8");
    this.mockMvc.perform(builder).andExpect(MockMvcResultMatchers.status().isOk())
        .andExpect(MockMvcResultMatchers.content().string("Train status"))
        .andDo(MockMvcResultHandlers.print());

Probably your project has a configured spring security. Than the controller requires some authentication - for instance a jwt token in a request header. In test your request does not have a valid value than You receive a 403 forbidden status
