The state of Queensland, Australia has a bucketload of railways (lines platforms, pedestrian access) that were not traced by license acceptors, and so will disappear in the license change if not re-mapped.

They're on my to do list, but I have a lot of other things on there as well, and will have less time over the Christmas break.

Some tempting places to work might be:

Gladstone, the port, the coal terminals (world's fourth largest coal export terminal), and the main line heading south

Dutton Park, a largish junction, and suburban lines heading E and W from there. (This junction is partially re-mapped.)

Acacia Ridge multi-modal terminal, and the main line heading N and S from here.

Port of Brisbane terminal.

Roma Street Station, 8 tracks close to the city centre

Bowen Hills Yards, really big

If you're tempted to help out, remember, please no copying across of line name or platform number unless you can find a legit source or have local knowledge.
I (or some other local) can easily add the line names later.

Please leave the station nodes for now, unless you have a legit source for replacing them. They'll be useful up until the license changeover, and I (or some other local) can use local knowledge to replace them later on.
