Instructions for use of these these bridges in a route of your choice:

Seven Bridges are available in this distribution they are identified as:

1   Description ( "One Track One Culvert no berm" )
    FileName    ( "1trnobrm.s" )
    
2   Description ( "One track One Culvert no berm handrail" )
    FileName    ( "1trnobrmhr.s" )
    
3   Description ( "One Track One Culvert" )
    FileName    ( "1tr1culvrt.s" )

4   Description ( "ONe Track Two Culvert" )
    FileName    ( "1tr2culvrt.s" )
    
5   Description ( "One Track Short" )
    FileName    ( "1trshort.s" )
    
    This is a minimal bridge which is used to cross a small creek on a short spur.
    
6   Description ( "Two Track Two Culvert" )
    FileName    ( "2tr2culvrt.s" )
    
7   Description ( "Two Track One Culvert" )
    FileName    ( "2tr1culvrt.s" )
    
8   Description ( "Two Tracks 30 Degree Angle" )
    FileName    ( "2tr30ang.s" )

    This is a somewhat specialized bridge which I needed where one double track rail line crossed over another at an angle.  It could also be used for small river bridging.

Follow these instructions carefully, making back-up copies of any files that you edit.

If you do not need all the bridges in your route, you can copy only as many of the .s and .sd files as are required for your selections.  The texture files are used by all the bridges.

----

1. Copy "Textures\PVculbridge.ace" into your route's TEXTURES folder;
   Copy "Textures\PVTerrain.ace"   into your route's TEXTURES folder:

   Copy "Textures\Snow\PVculbridge.ace" into your route's TEXTURES\Snow folder
   Copy "Textures\Snow\PVTerrain.ace"   into your route's TEXTRUES\Snow folder

   The PVTerrain texture is a predominantly green texture, appropriate for a summer or grassy route.  It is used as a berm texture only.  If you this texture is not appropriate for your terrain, you can substitute a different 256 x 256 texture.  It must have the same name (PVTerrain.ace) and No transparency is used.

2. For each bridge which to be used in your route, copy that bridge's files with the .S and .SD extensions into the SHAPES folder for your route.

3. The next step requires that you edit your route's .REF folder, which contains a list of all the shape files used in your route.  Cut and paste the file PVBRIDGES.REF into your route's .REF folder.  If you are not using all the bridges, then delete the information fpr the bridges you will not require.  Save edited .ref file  as a UNICODE format document.
   
   Note that a object classification heading of "PV BRIDGES" is used to group these bridges in your list of available objects in the Route Editor.  You do not have to use that heading, for example it could be changed toe "Bridges" or "Structures" or any other term of your choice.

   When you use the route editor to place a bridge at a location, change the bridge's properties so that it is a "terrain object".  Then the track ties and will show up on the bridge surface, rather than along the ground beneath it.

----

The textures (.ACE) files and models were created by myself (Phil Voxland) based on prototypes of bridges along the ore and logging lines in northeastern Minnesota.  They are offered for use in the public domain. I would enjoy hearing from anyone who eventually finds them useful in their own route creation, whether for private, non-commercial, or eventual commercial use.

If you use any of these bridges in a route, or in a collection of route building files which you redistribute freely or sell to others, acknowledgement of the authorship of these components is requested.
