"drawbridge" crossings of cane lines over QR

[Eddie Oliver <eoliver@efs.mq.edu.au>]

I am looking for information about the locations of the "drawbridge"
crossings (replacing former diamond crossings) where sugar cane lines
cross Queensland Rail tracks. Apparently complete lengths of
cane-railway  track can be lowered to pass across the QR tracks when
required, but are otherwise lifted out of the way.

A complete list of such locations would be ideal, but just a sample
would be better than nothing. I realise that individual cases have been
mentioned from time to time in journals like Light Railways, but I am
hoping for a more consolidated source.

Any information about how these crossings actually work would also be
valuable.

Can anyone help, please?

Thanks in advance
