If you get the title of the thread, basically everytime you see a crossing that now has E-Bells in place of the older style mechanical bell at any level crossing in Melbourne, you post it in this thread. I'll start off by saying that every crossing on the Sandringham line now has E-Bells fitted on them. These replaced various mechanical bells (including a rare Safetran Mechanical Bell in Ripponlea, the last in use in Metropolitan Melbourne.)
Most crossings around South Geelong have them.
The upfield line seemed to be the first to get synthetic bells I recall these as long ago as 2003, although they are different to the ones you are referring to, and around the same time, I remember Kensington having these too.
I remember Murrumbeena having these quite a way back too (but not for much longer!)
