I too visited Northlandz, maybe six or seven years ago. As GRJ and RT pointed out, it was disappointing. Hardly any trains running and those that were making the rounds were two and three car freights with a single F3 or Geep at the head end.
The original builder probably had grand plans, but it appeared, to me, that he may have taken on too large a task and got bogged down in building endless mountains and wood trestles.
