Rocrail

Rocrail is a freeware software package for controlling a model train layout from one or more computers. Users can run trains directly from a computer, or have some run automatically with manual control for any others. Rocrail uses a client-server architecture that communicates via TCP/IP, and the client and server do not need to be on the same computer. Rocrail can be used from a single computer connected directly to the layout, or via any other computer on a home network, or over the Internet. Rocrail also has an HTTP interface, which will let the layout run from a web browser. An Android app is available. The server program runs on a computer connected to the layout by one of the standard computer interface setups, and supports many command stations. The Rocrail client connects to the server over a network. The client can also be used by itself to plan layouts. There is no need for the server or the layout to be running to edit plans.
