Above is the GE Locomotive ‘Trip Optimizer’ Software. You can see a nice video about it here -> GE Locomotive Trip Optimizer

And here is a really cool video of GE intermodal at work, with the Trip Optimizer of course.

I’ve borrowed some of the graphic layout ideas from this to make the GUI for my phone app- Not quite sure what I want yet but I like this minimalistic implementation.


Again, the idea here is that the phone sits in the cradle (see below) and communicates with the Xbee master in the cradle via bluetooth. The Xbee master reads the knob and the buttons and syncs up with the phone app to keep the display refreshed. The Xbee master controls the Xbee client in the locomotive and also can query the locomotive for speed (via a wheel encoder) and current draw (via a pololu current sensor). There are also hooks available for an RFID reader (I use a somewhat pricey one from Sparkfun – $33) for position information.
