Cradle Valley Monorail

I've often pondered the Cradle Valley traffic problem and been frustrated by the apparent non-sensical boom gates. How about this for a crazy idea...
A ground level monorail from the Visitor Centre to Dove Lake with a branch up to Waldheim and the cabins. It would completely replace the road from the Park boundary at Pencil Pine Creek allowing an even greater level of revegetation than what has been achieved with the new single lane road sections.
A driver could be on-call through the night for late/early bushwalkers and emergency requirements. Paint the carriages and rail to blend in with the button grass and it would almost be invisible.
Now...
I wonder if anyone has a slightly used monorail system going cheap...
P.S. I've just spotted the posts about the Fjordland proposal in Kiwiland and, yes, I have heard sound grabs from the relevant Simpsons episode.
