Looking at your new pic, and since you say modern era, I would say 2. Your beams aren't tall enough for one. The prototype would strongly like to avoid the one between the tracks as that is likely railroad owned ROW that close to the switch. I think one as close to the bank as you can get but still have it full height, and then one at the edge where you show it.
