Bamboo train still running (Sep 2014) and worth it?

Hi everybody,
I was surprised to find out that the bamboo train (norry) is still recommended in this forum as a highlight in Battambang. I have seen a beautiful documentary about it (2009, in German) but they said it would be closed by 2011.

Has anyone used the bamboo train recently (Aug/Sep 2014)?
Is it worth riding it beyond the stretch frequented by tourists?
How do I find it when I'm at Battambang?

Thanks for your help.

Matthias
