## 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'

**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'

**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:** 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 offset value perpendicular to the PGL (Proposed Ground Level) can be specified for the rails.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openbrim.org/templates/concrete-box-girder-bridge-workflow/superstructure-attachments-cbg/rail-cbg.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
