9m wide?
Those are some fat train tracks. Usually they're barely over 1m wide.
I’m guessing they include all the necessary infrastructure, not just the tracks themselves. And it does say “in each direction”, so we’re talking two tracks.
Honestly you're in the 11-15m range in most cases, because you want lineside equipment (signal cabinets, masts, cable routing etc) and ideally a 4WD path for maintenance access.
9m is doable but you don't built an entire system like that unless you really have to. Equally, your roads have hard shoulders and crash barriers.
Checks out:
Standard guage rails are 1.435m wide, plus surrounding space because trains are wider than rails plus a second track.
