Wonder if the suggestion of the Cog Railroad - Mount Washington - NH.... Took it when I was a child on a Family Vacation and what an experience to take. Thought it would be a challenge like many of our simulators climbing mountains with different various engine techiques. Just a thought.
Excellent idea and for DTG they can sell this as the Mountain Railway pack Switzerland Lucerne Interlaken UK Snowdon Mountain Railway Germany Stuttgart or Bavaria and US Mount Washington.
