Can´t go on in Chapter 6

[ete77]

Thanks a lot for your help. It was the right good tip.
But now, I´m back to the "trainstation". I think I have to switch off the Laserbarriers. There are two buttons, too. But when I push these two nothing happens, except the noise in the backround.
How does it work, or how can I switch off these laserbarriers?
