CaltrainPY
I started on the Python version since I wanted a schedule for my Cingular 8525 PDA/smart phone running Microsoft Windows Mobile device after I had migrated away from a PalmOS device which had a great Caltrain schedule application. It was the inspiration for me starting this project.
The GUI is done using the Tkinter package. Unfortunately Python doesn't run very well on Windows Mobile, which lead me to start working on the Javascript version (see below).
It would be interesting to see if the Python versions works well on OpenMoko. PyGTK might be a better option than Tkinter in that case, at least if I am reading the OpenMoko Python page right.
Guido van Rossum expressed interest in a port to the Nokia S60 platform. The Nokia Python for S60 and Python for Series 60 tutorial seem like good resources to get started. But please note that the online Javascript version already works in Nokia phones using the more capable WebKit-based browser (see below).
CaltrainPY version is available from the Python Package Index aka Cheeseshop, just easy_install caltrain.
The Python version can also work as a library to screen scrape the online Caltrain schedules and provide output in various formats, including JSON.
