Browser Requirements

An up to date browser is needed which supports:

Tested browsers

Browser Version Remark OS
Safari 8 OS X Yosemite, iOS 8, iOS 91)
Chrome 43 OS X, Windows, Linux, Android
Firefox 38 Highly recommended for Android is version 54+. OS X, Windows, Linux, Android
Opera 29 OS X, Windows, Linux, Android
Edge 10 Windows 10 64bit

A complete list of supported browsers is found on the jQuery Mobile Site.


  • An up to date Rocrail installation.
  • WLAN (WiFi) in case of mobile devices. The quality of the signal should be at least 50%.
  • The mobile device should not be older then 2016, especially in case of Android devices. (Android before 2016 have generally poor JavaScript performance.)


In the Rocrail properties dialog there is a RocWeb Tab on which the needed port and directories can be set. This must be done for every individual Workspace.
The SVG Theme paths are identically interpreted as by Rocview.

The images of locs, wagons etc. are only displayed in rocweb, if the image path in rocrail setup is correctly2) defined.


Install directory. Rocrail RocWeb properties.

In the install directory of Rocrail a directory named web should exist; If not the the Rocrail install must be updated.
This directory contains the HTML and JavaScript files needed for Rocweb.


If Rocrail was installed in the Applications directory the web is found here:



The web directory is found here:


Chromium Browser

The most easy way to launch Rocweb under Linux/Raspbian is to use the Rocweb shortcut in the "Other" menu.
Raspbian comes with Chromium pre installed, and on other Linux distributions the following command will install it:

sudo apt-get install chromium-browser

The shortcut starts Rocweb without any menu and navigation bar like this:

chromium --app=http://localhost:8088

The localhost parameter can be replaced with any computer name or IP address.

Browser URL



  • This is only an example IP address which should be replaced with the IP address of the Rocrail Server computer.
  • Do not use to same port number as used for the HTTP Service Port.

The "Help/Info" dialogue of Rocview will show you the IP address.


Needs Rocrail revision 11.200+


With the optional parameter z a ZLevel can be preselected.
Example of selecting ZLevel 1:

Video demonstrating the handling of Rocweb

This video explains the operation of a layout by Rocweb (in German). It includes the following chapters:

  1. Installation and setup
  2. Starting Rocweb in a web browser [03:40]
  3. Operating Rocweb part 1 (basic configuration, options, system) [07:52]
  4. Operating Rocweb part 2 (layers, zoom, track power, automatic mode) [11:46]
  5. Operating Rocweb part 3 (loco functions) [13:36]
  6. Operating Rocweb part 4 (switches, signals, block functions and a concluding demo) [18:40]

For iOS 9 Rocrail must be at least 9907.
The path must be achievable from the server
