Yes, yes it is Matt. Have you noticed, it appears from the limited information those pictures show that this could be something we have never seen before. In what I assume is the maintenance shed, notice the placement of the catwalks.
They butt right up to the edge of the rails, just placed higher than the rails. You could not place cat walks like that on most other B&M's as most, if not all of their trains have a slight overhand each side of track, which means more of a gap would be needed between the catwalk and track when, even more visible when viewing from an elevation like these plans. Even if the overhang is small, they have a little overhang. This appears to not be the case with this.
Saying that, it could have a flat platform at the bottom where your feet stand that could stick out each side, the cat walk allows for that but it appears it could not accommodate the rest of the train / bogie configuration from existing trains. As the overhang on most existing rides extends for the height of the train. Could we be seeing a more central riding position here, perhaps the riders being sideways to the way the train moves, this cat walk supports that theory. This is also like surfing, as you generally stand sideways to the way of motion when you surf.
The placement of those catwalks, do not appear to be able to accommodate any existing B&M train. That is interesting indeed. Unless of course, I am looking at the plans wrong, but I do not think I am. This plan does support a brand new type of train, I am sure. Amazing what information you can extract from a simple catwalk eh!
