Well, if the system is a bit interactive, some more things can be done to assist the blind person. I am compiling a document which I will post soon. and if the hand held device can do a little bit more at the control of the user then lot of things can be done.
As a balance between low cost and maintainence as JTD suggests and interactivity as desired, we could have the same repeater system giving out not just plain speech but interactive speech, like a tiny voice enabled web page. When the user is in close proximity to the railing transmitter, it dumps an entire website into the user's device. This website will be based on the particular railing position. The user then interacts with it asking it for detailed addresses and locations around it, as desired. The device can have a keypad in braille format where the user punches queries and the device reads out the answer. Once the user moves on to another railing, the old data is replaced by a new web site.
The advantages of this system will be that the railing will have to be fed once with the respective web pages and after that its sealed against dust and water and maintainence is not needed. The user gains by getting to ask customised queries.

Rony.
