Scientist 1 : "Well, well, well, if it isn't our intrepid adventurer, right on time for the second anomaly. I must admit, we didn't expect you to make it. Quite the pleasant surprise."
Scientist 2 : "What do you mean, 'we'? I always believed in you."
Scientist 1 : "Yes, yes, of course. The world isn't going to save itself. Our radiation meter here has detected the second anomaly right in this very building."
Scientist 2 : "Ah, but we can't get distracted. Focus! We've done our homework. This building, you see, is no ordinary structure. It used to be the station for the Prince Henri line. It connected the fine towns of Ettelbruck and Grevenmacher, back in the day when people had time to go from one place to another without needing to check their phones every five seconds. We even found a recording in the archives – an announcement from when the trains were still running.
Scientist 1 : "Precisely! But, here's the rub and trust me, it's quite a rub. We can't for the life of us figure out when the last passenger train chugged down the Prince Henri line.
We know it started in 1874, that much is certain. But the last day of service? That's when you come in, dear guest. Your mission involves listening this rather old and crackly recording and making sense of the year."
