  I may look into the raspberry pi route. I bought one when the first came out, powered it up and played with it a bit but got frustrated when I could not get a schematic or even a data sheet on the CPU.
  
  OT and speaking of schematics, is the schematic available for the sbrick? Would I get in trouble for publishing one?  less

Octave is a fine product for what t does, but it not seem to support things like building GUIs, image capture and processing, and communications with external instruments. It may be possible to implement a lot of this if you are very familiar with Linux, but I am not. The home version of Matlab with a the tool boxes I want will run about US$400. I think that is reasonable.
  
  The EV3 would be fine but somewhat bulky and expensive solution for controlling a switch yard, but going the EV3->IR ->PF route to control trains has serious limitations.
  
  Reed switches and other sensors along the layout would certainly work, but I would really like to have a wireless solution. A cheap webcam seems like a nice solution.  less

  The image capture / image processing capabilities of Matlab coupled with the sbrick would be idle for controlling multiple trains on the same track and doing other complex tasks. Matlab has recently released a 'home' license in the US that is affordable. I really want to get Matlab working with sbrick. I suppose I could also wait for Matlab to support BLE if they do not already.
  
  Yet another possibility would be to build my own external BLE dongle.  less

  I want to be able to control My sbrick through programs like Labview and Matlab. I do not believe these programs directly support BTLE yet. Obviously, they would have a hard time directly supporting BTLE without native OS support, which is sparse. They do support COM ports. It seems I can buy USB BTLE dongles with drivers that make them virtual COM ports. Is this a viable path? Are there any specific hardware recommendations?  less

  How about a small sbrick?

  I Would love to see a very small single-channel sbrick that snaps directly to a 9V battery. It needs to have very low standby current draw. I want to use it to light rail cars, control railway switches in a yard and run monorails.

  A 9V battery adapter for the current sbrick would also be welcome. I ca make these, but I would rather just buy them.
