A little more to show. Setting the switch in place on the existing line where it will cut in gives me the location to install the new support post to carry the off end of the new bridge. This also sets the alignment to the curving grade around the block wall. You can see a couple of the grade stakes in the left background, I set them at approx. 2 foot spacing. This spacing worked out almost even distances around the curve and it sets my grade at about 3/4 inch per 2 foot.
Here you can see the trestle bents in decending order with their 3/4 inch drop from one to the next. It is a steep grade but workable especially using small mining and geared locomotives. The bents are not built to scale but rather built to endure and carry the top beams and have a big enough landing area for the screws to attach them.
The bents installed. Obviously the long leg on each one (shown in the previous picture) was/is for burial in the ground to provide stability and strength. Here also is a pretty good view of most of the “Shaft House”, I have built a new 3 inch high “foundation” for the building to raise it high enough for the ore car dumps. (More on that later)
More later.
