Place Wire Run
Places one wire run or more between the selected reference lines.
- Select geometry or select
- Select geometry method creates a wire path that runs through whole geometry ignoring turnouts.
- Select geometry sections method is user-selected geometry sections that are divided based on turnout locations. When a section is selected, this section is highlighted up to next turnout location. At this location a fork selection is requested from the user (similar to complex geometry command). Right click to finish selection. The final path highlights, left click to accept.
- Select start reference line or overlap.
- Select the end reference line or overlap
Standards used while placing the wire is read from the reference lines. If there are multiple standards read from the reference lines, then the tool asks for user to select which standard to be used.
Wire placement automatically creates overlaps based on the maximum wire length or maximum number of spans defined in the standards.
Wire stagger, contact wire height, encumbrance, when to use stitch wires, etcetera, is read from related tables in the standards except overlaps. On overlap areas those values are read from related overlap tables.
Wire stagger is defined as negative or positive. Negative is to the left of rotated axis, and positive is to the right of rotated axis.
Wire alternates (zigzag) between left and right stagger on a straight geometry, to even out pantograph wear. On the curves stagger is always to the outside of the curve. That is on a left-hand curve stagger is to the right.
Type of the overlap to be used is defined in the selected standards. Normally on straight portions of the geometry 3 span overlaps are used, and on curves 4 or 5 span overlaps are used. Selection of the overlap type is based on radius and speed.
Wire Run Manipulation
Manipulators at the start and end of wire runs allow selecting the end of a wire and dragging it to next/previous reference line.
