The second iteration of the new track type remained largely similar to the first, with only incremental refinements in detail.
The largest alteration was offsetting the spine standoffs by half of a tie spacing to increase the track rigidity by essentially doubling the frequency of connection points per section.
Additionally, the tie spacing was increased by 5mm to a total distance of 25mm, in turn reducing the total number of ties required while having a near negligible change in rail stiffness.

Some laid out "exploded views" of how the track and supports fit together.
|
Alterations to the base of the supports and footers were made, including adding hexagonal plates with decorative bolts as well as more simple and discrete connections between the supports and footers.
The base securement was reverted to the original method of using a singular screw that goes through the footer from the bottom and threads into the underside of the column.
