Went passed it today, looked like broad gauge and photo from google maps
No railway runs/ran through Eddington.
The Image has the railway running East - West, but the Maryborough - Dunolly railway runs North - South ?
Looks like the best way to find out is call in and didn't have time to call in today was getting late.
To be honest, i'd just leave the people alone. They probably won't take well to a bunch of people turning up asking around.
If they want people to know about it, i'm sure they'd put a sign up or publicize it.
Bing maps shows it stretching slightly further than Google.
