Research Railcar

Exploration Stage: Station
From: Conductor
Description: The City sent me a strange dream in which I was looking for... something like a toy observatory on wheels. I’ve seen this once in my life. It was part of a train bringing scientists to study the northern lights. Will you find the observatory railcar?
Completed: Look at this observatory railcar - it looks so small, but there are two telescopes and everything you need to study the sky... There’s a letter too. This time it’s "L." Let’s find the rest of the railcars. Maybe we can form a word with them.
