Select 'Tack Edit'
from the Linear Draft toolbar. Follow the prompt to select a structure.
Select 'Re-Associate Main Tracks' on the right hand side of the form.
You will then be prompted to select both the left and right rails that are to be associated with the structure. Once selected, the tracks will be re-associated and you can exit the form.
All wires and equipment will be automatically adjusted to suit the new track position.
N.B. If the re-association of the tracks takes the equipment out of its reach value range then the equipment may not display. You will be required to adjust the RECOS of the mast. Details of how to adjust a structure can be found here.
