In addition to the editor of railways, EEP has a separate editor for rail structures and this is what we will discover in this article.


Note : EEP contains four similar editors for editing railway, road, tram and river infrastructure. The construction principles remain the same from one editor to another for all models.

This article is divided into three main chapters:

  1. The presentation of the editor located in the 2D plan window with its two sections. This will allow us to choose a model among different categories such as stations, platforms, bridges, etc …
  2. The installation and configuration of the model and the various settings of its properties,
  3. Choose a track style before posting a model

Presentation of the editor

In the first section at the top are grouped the various categories of objects (Turntables and ferries, Stations and platforms, Bridges and tunnels, etc …). All you have to do is open a folder and click on the checkbox of the desired subcategory to immediately see the corresponding models appear.

Here for example, the Bridges and Tunnels category is selected and the Bridges subcategory is checked. Immediately, all the railway bridges appear in the list of models at the bottom. In a category with several subcategories, you can check several and even combine different main categories. In this case, all affected models will be added to the bottom list.

You can also create your own categories yourself, filter and display the models according to several specific criteria (Model designer, country, period, etc.). See the article Inserting  models in the section Customizing categories et Filter elements to learn more about these features.

In the second section at the bottom are displayed all the models corresponding to the selected subcategory. Once you click on a model, a preview is displayed in the dedicated area so that you can view it in all its forms. Click on Overview of models to learn more about manipulating objects with the mouse

Track style before laying a model

The track style applied to a bridge (or any other model) is the one chosen in the Track style drop-down list in the Railway tracks editor. Therefore, if you choose the Standard Timber sleeper style, this style will be applied. You can therefore apply the desired style according to your layout.

Below is the same bridge with two different styles (standard wooden sleepers at the top and concrete sleepers at the bottom):

Laying and setting up a model

To accompany us during this tutorial, we are going to choose the US 4 Bridge model. Like all models, you can find common properties such as position but also properties specific to each of them. For example, you will find models where fire management will be implemented or even light or smoke management.

Sample preview for the US 4 Bridge

Nothing could be simpler to place an object on the layout: select the model in the list and click where you want to place it. Then you can readjust its position if necessary. The object will appear in 2D and 3D editors as below:

Display of the bridge in the 3D view

Do you remember the track properties window ? Well there is also a properties window for our bridge just like there is a properties window for each model.

Object properties

For now, let’s start by opening the bridge properties window. As for the track, right-click on one of the model track to open the contextual menu:

As this model was designed with 4 tracks, you can access the properties of each of them by selecting the Track Properties command like any other railway track. But what interests us here is the Object Properties command to open the bridge properties window:

Properties of the US 4 Bridge

In this window, you can distinguish two main areas:

  1. The Object Properties  section with the input boxes and options,
  2. The Movable elements (axes) section.

Three buttons respectively allow:

  1. Associate a tooltip with the object,
  2. To write or modify a text. The button is disabled because this model is not eligible for this functionality (More information in chapter 5.6.4 – Models designed for personalized signage in the EEP16 manual,
  3. To validate your choice.

In this window, the properties common to all models are grouped together. In order you have the position of the object on the X and Y axis, the height and relative height of the object and the tilt properties on the three axes X, Y and Z.

Checkboxes allow you to activate or deactivate the properties specific to the current model and as all models do not necessarily have the same ones, some are inaccessible from one model to another. For example, some models offer management of fire (fire), light or even smoke while others do not.

For this bridge we have three applicable properties, these are electrification, shadows (depending on lighting, the bridge casts shadows on the ground or on surrounding objects) and SSAO mode.

Movable elements

Do you remember the sports car model in the article Standard functions – Position of moving parts ? We had the car’s spoiler as a moving part. There is no movable element here so the list is disabled. If we had had the sports car instead of the bridge, the spoiler would be selectable from the list and configurable exactly as in the control window (3rd tab) or the toolbar in 3D mode.

Below the movable element’s slider scale you will find a label showing the Lua name of the bridge. This name can not be changed. We’ll come back to that later because before we get into scriptwriting with Lua…

We have just discovered an example for rail infrastructure. Keep in mind that laying and manipulating models are based on the same actions. Only the properties may vary from one model to another.
