Add a railway to your multimodal simulation in InfraWorks

00:03

Train networks are fundamental components of many multimodal simulations.

00:09

In InfraWorks, the process of adding a railway to a simulation model begins with adding and connecting railway segments.

00:17

Begin with a new InfraWorks Mobility Simulation model open, and ensure you are working in Orthographic mode.

00:25

On the Layer tab, under the first Aspect column, 0 – General, ensure the following layers are turned on:

00:34

Walk Centrelines, Walk Connections, Walk Edges, Handle – End, and Handle – Other.

00:42

Also, since you are working with rails and lanes, select Links, Lane Streams, and Lane Midlines to turn these on as well.

00:51

You are now ready to start adding rail segments.

00:55

Use the ViewCube to orient the model to plan view, then zoom out a bit with the cursor at the desired location of the first rail.

01:03

Right-click and select Rail > New Rail at Cursor.

01:08

This opens the Parameters for New Rail dialog.

01:12

Here, you can specify the class, length, direction, number of lanes, lane width, and speed limit for the railway.

01:22

In this example, leave the default settings, and click OK.

01:27

The railway segment now displays in the Mobility Simulation model.

01:32

On your keyboard, press ESC.

01:35

Next, pick the rail, move it down below the viewport, and use the ViewCube to rotate the rail segment into a more complex angle.

01:44

Repeat the process to create another rail segment.

01:48

Right-click the location you want, then select Rail > New Rail at Cursor.

01:54

You are now ready to connect the two railway segments.

01:58

Use the ViewCube to zoom in to your model.

02:01

Here, there are design entities you need to be aware of.

02:05

The blue lines on the rails are links and the yellow circles on each end are nodes.

02:11

Multi-select the nodes on the two facing segment ends you want to connect.

02:16

Once selected, the nodes turn from yellow to red.

02:20

Now, right-click and select Node > Combine.

02:25

A blue line appears connecting the node at the top end of the upper rail to the top end of the lower rail.

02:32

Currently, the blue line appears outside of the top rail, but that will be corrected once the two rail lanes are connected.

02:40

At the top end of the lower rail, click the left lane, and then, on the bottom end of the upper rail, click the corresponding lane.

02:49

Right-click and select Lane > New Stream.

02:53

You can see that the two left rail lanes are now connected.

02:57

On your keyboard, press ESC, and then repeat the process for the other side.

03:03

Select the lanes to connect, then right-click and select Lane > New Stream.

03:09

If the rail lines do not connect properly, as in this case, press CTRL+Z to remove the last connection.

03:17

Then, right-click again and select Lane > New Stream to create a proper connection.

adding and connecting railways to a model is an important first step for building a multimodal simulation model.
