# Trams

Advice on how you can make the most of the data provided by the Tram on Road Feature Type.

## Introduction

**Tram on Road Feature Type definition**: A subsection of the Road Link geometry that indicates where there is a Tram within the road area.

Trams are rail tracks dedicated to the movement of passenger tram rolling stock within big towns and cities. Understanding where tram tracks are present on the Road Network can provide useful information for maintaining both road and tram assets, understanding risk for road users sharing the same space as trams, and supporting transport network management.

Within the OS NGD, there are several feature types which will allow you to view and analyse tram track information, each with their own design and intended use cases.

These feature types are all found within the OS NGD Transport Theme and are listed below:

* Tram Presence attribution provided on the [Road Link Feature Type](/osngd/data-structure/transport/transport-network/road-link.md)
* A dedicated [Tram On Road Feature Type](/osngd/data-structure/transport/transport-network/tram-on-road.md) to help you understand the extent of tram track presence on the Road Network
* A network representation in the [Railway Link Feature Type](/osngd/data-structure/transport/transport-network/railway-link.md)

The following sub-pages give more detailed information about the above three representations and how they can be used to allow you to decide which one best suits your use case:

* [Tram Presence attribution on Road Link](/osngd/using-os-ngd-data/os-ngd-transport/trams/tram-attribution-on-road-link.md)
* [Tram On Road Feature Type](/osngd/using-os-ngd-data/os-ngd-transport/trams/tram-on-road-feature-type.md)
* [Trams in the Rail Network](/osngd/using-os-ngd-data/os-ngd-transport/trams/trams-in-the-rail-network.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.os.uk/osngd/using-os-ngd-data/os-ngd-transport/trams.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
