If we needed additional seating capacity, I guess that would be a worthwhile avenue to explore. However, as it stands, only our Easter and Christmas trains come close to our train capacity and we will be adding another coach (No. 9) within several years. And this capacity alone, doesn't spell success for us. We need to have appropriate ancillary facilities to match the capacity of our trains. In this sense (station platform capacity, speed of visitor flow, to name a few) we are already close to our peak on those days.
I believe we do have J&S floorplans for #6, so it shouldn't be impossible to find out about those folding seats. It's a neat idea. As for coach 6, or coach 1 for that matter, once we reach 218 or Head Tide I could see it being used to carry bicycles so that visitors could do a train-bike loop or some other use baggage related. We could use the slot in the postal section as a place for visitors to mail postcards sold on board the train. There are lots of options we just have to get creative.
The last thing I want to see is us falling into the same habits as other railways. While modern additions could be seen as a draw, they can also be a distraction from the atmosphere that you are trying to create and the points that we are trying to reinforce. By trying to cater to the masses, we could mistakenly dilute our mission/goals and fall short by trying to be a jack of all trades and a master of none.
For example, Cumbres and Toltec has a gift shop and concession car. They also have absolutely world class scenery, so the authenticity is not nearly as much of the attraction. If the scenery wasn't so great, and the railway wasn't so impressive the experience would have fallen short. Many cars are simply passenger car bodies built on freight car frames. If this was the sole attraction, without the amazing locos and beautiful railway, I probably wouldn't have gone.
To me, our draw is our authenticity- it is our strongest hand, so to speak. We should capitalize on that aspect to the greatest degree possible. I would love to see news butchers and vendors going up and down the aisles peddling their wares and platform vendors at the bigger stations- if there is evidence that this once existed. No railway, to my knowledge, is providing this experience, and it could provide an important convenience, while also giving a snapshot into how this mode of transportation once functioned.
