We're using Python for a computer-controlled railway simulation system at a german university. It consists of a rather large model railway network, constructed with realism concerning railway operations, coupled to realistic railway control centre technology. Uses are education of students, training of railway employees, teaching of railway basics to career changers and managers, and simulation of new operating procedures. Python (2.5.1) is used here for - the main database where all states are kept (signal aspects, given and actual turnout states, track occupation ...). It's a simple binary protocol using TCP; the server maintains string:int pairs in a Python dict. It's made with Twisted and running under twistd. - the automatic drive controlling software of the model trains. It listens for changes of signals and track occupation and controls the model trains using a commercial digital model railroad controller attached to /dev/ttyS0. Also using Twisted/twistd, and pyserial. - various helper scripts and little servers for small functional units (tramway reverser, level crossings) Momentarily, I'm working on a program that simulates a german relais rail control centre of a certain type (also using Twisted). We already have it in C++, but it's difficult to maintain and needs a rewrite because of various bugs. Starting to use combined wxPython/Twisted apps in the near future is likely. We're mainly using Debian Sarge as OS. pylint is also recently used to check the code. Right now, we use Python for approx. 2 years. Other languages used are C, C++, and Perl (ugh :) ), for other core applications and the microcontrollers (interfacing with the railway components). We mainly have "low-end" computers (100-800 MHz), but the performance suffices absolutely. The source code is maintained using Subversion.
