<h1>Edit Level Crossing</h1>
|
|
A level crossing is a special piece of track that represents two tracks crossing at grade. A
|
|
level crossing is commonly referred to as a diamond. A level crossing has four connection
|
|
points, and two tracks, designated 1 and 2. When a level crossing is created, track 1 is the
|
|
horizontal track, and track 2 is the inclined track. The angle between the two tracks, the
|
|
incline of each track, and the length of each track may be varied by dragging connection
|
|
points with the meta key pressed. The center of the level crossing may be positioned by
|
|
dragging the center circle with the meta key pressed (see the help bar for which key is the
|
|
meta key for your operating system).
|
|
<p>Optionally each track will be either <em>mainline track</em> or <em>side track</em>
|
|
depending on the mainline track or side track designation of track segments connected to each
|
|
track. Also optionally you may independently assign each track to a different block. If a
|
|
block name is entered in the <strong>Block: Name</strong> field of the tool bar prior to
|
|
creating a level crossing, that block is assigned to both of the tracks. Each track may be
|
|
assigned a different block in the Edit Level Crossing dialog. The Edit Level Crossing dialog
|
|
also allows a Create/Edit Block dialog to be requested for each of the two blocks, so
|
|
information for these blocks may be entered or changed. Blocks are discussed more fully on
|
|
the help page of the Create/Edit Block dialog.</p>
