Question: I'm thinking of doing a one-way hike to the top of Mt. Washington leaving from the Pinkham Notch visitor center (so I can go up Lion's Head) and taking the cog railway down. Is it possible to take a one-way trip on the cog down? And is there any shuttle or other way to get from the Cog Railway Base Station back to my car at Pinkham Notch (and what might it cost $)? Any suggestions or opinions?
