Rail
Section: Assign a section to be used on rails.
Deck: Upon selecting the connected deck, the rail will be placed on top of it and the vertical elevation will be adjusted accordingly.
Start Station Option[Deck Start/Input]: If you want to automatically assign start station to the deck start, select 'Deck Start'. If rail starts at different locations along the PGL, choose 'Input'.
Start Station: If the "Start Station Option" is defined as 'Input,' this column can be used to specify the rails' start station. Otherwise, this parameter will be marked as N/A (Not Applicable).
End Station Option[Deck Start/Input]: If you want to automatically assign end station to the deck end, select 'Deck End'. If your rail ends at different locations along the PGL, choose 'Input'.
End Station: If the "End Station Option" is defined as 'Input,' this column can be used to specify the rails' end station. Otherwise, this parameter will be marked as N/A (Not Applicable).
Gauge Distance: The distance between the rails, also known as the gauge, can be adjusted using this parameter.
Transverse Offset: The transverse offset is measured from the PGL. A value of 0 indicates that the center of the rail is located at the PGL. Positive values indicate offsetting the center of the rail to the right, and negative values offset the center of the rail to the left when looking upstation along the PGL.
The positive direction of the Y-axis will be to the left when looking upstream along the PGL. However, based on the requests of engineers who have been using OpenBrIM for their bridge projects, positive transverse offset values will indicate the right-hand side when looking upstream along the PGL. This distinction should be taken into account when defining the location of bridge elements using transverse offset values (where positive transverse offset indicates the right side), as well as when making definitions related to FEM and loading (where positive Fy indicates the left side along the PGL).
Ballast
The properties of the ballast of a rail can be defined using the parameters listed below. For a visual representation of each parameter, please refer to the figure below.
Ballast Height: The ballast height can be specified using this parameter.
Ballast Shoulder: The ballast shoulder can be specified using this parameter.
Ballast Slope: The slope of the ballast can be specified using this parameter.
Sleeper
The properties of sleepers of a rail can be defined using the parameters listed below. For a visual representation of each parameter, please refer to the figure below.
Sleeper Width: The width of the sleeper can be specified using this parameter.
Sleeper Depth: The depth of the sleeper can be specified using this parameter.
Sleeper Thickness: The thickness of the sleeper can be specified using this parameter.
Sleeper Spacing: The spacing between sleepers can be specified using this parameter.
