# Rail Construction \[CBG]

Construct one or more rail (railroad track) objects as part of a construction stage. Use this when rails are placed on the structure as the construction sequence advances.

## General

**Stage:** Construction stage in which the selected rails are activated.

**Rail:** List of rail objects constructed in this stage. At least one rail must be selected.

**Self Weight Factor:** Multiplier applied to the rail's self weight when the rails become active in this stage.

**Stiffness \[NO/YES]:** When YES, the rail's stiffness is added to the analysis model during and after this stage.

## 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/construction-cbg/superstructure-construction-cbg/rail-construction-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.
