The Super It action within the link maintenance tool allows you to convert a sequence of regular blocks into a superblock by making the original blocks “inferior” with the superblock representing them for routing purposes. It combines the activity of one disconnect followed by four connects that you would have to do otherwise.
You need to have two link objects of regular link types (LUL, LUR, LDL, LDR) in spot #1 and #2. A prerequisite is that the link objects represent the outer boundaries of a stretch of track built by existing connected blocks for consideration of a superblock – basically the left and and the right end of the stretch of connected blocks. There must not be any switches of any type, crossings, or control points with signals (visible or hidden). Control points with distant-only signals and/or triggers are allowed. In spot #3 you must have the super block object (link type “block”), which must be empty and not in use, i.e. just created and made superblock.
This action is not reversible within the link maintenance tool. However, you can undo it from the main panel or the detailed list panel.
This example shows the setup to put block B3 in charge of a stretch of blocks B0 left side to B2 right side. The right side of B0 and the left side of B2 point to other blocks within B0 and B2 (here just B1) .

Note that in this example, the left side of B0 was originally NULL. If there would have been a linkage to another object, the value would appear in upper left link of B3, the same goes for right side of B2 into upper right link of B3. The linkage from B0 to the right and B2 to the left are not modified. Also note, that the link type and value in spot #3 does not change, as it represents the whole block.
