Just some context for the anime Train to the End of the World, the girls are taking the Seibu-Ikebukuro line https://en.wikipedia.org/wiki/Seibu_Ikebukuro_Line from Agano (31) and are heading to Ikebukuro (1). It's 30 stops, and the express usually takes 1.5-2hrs normally.
They spent Episode 2 taking the train from Agano (31) to Higashi-Agano (30).
The effects of 7G made the gaps between stations longer. It also had mysterious effects on the Koma River, which the tracks run parallel to for a few stations, become some kind of lake instead.
So the map from the duck boat guy in episode 2 seems to correspond to the stations on the Seibu-Ikebukuro line:
1) Agano: Bear
2) Higashi-Agano: Mushroom
3) Musashi-Yokote: Fox
4) Koma: Octopus/Squid/Flower?
5) Higashi-Hannō: Circle?
6) Hannō: Ghost
7) Motokaji: Buildings
8) Bushi: Person praying?
9) Irumashi: Stomach?
10) Inariyama-kōen: Multiple people
11) Musashi-Fujisawa: -
12) Sayamagaoka: Pipe smoking
13) Kotesashi: -
14) Nishi-Tokorozawa: Fart jumping?
15) Tokorozawa: Sushi
16) Akitsu: -
17) Kiyose: Zombie
18) Higashi-Kurume: Fighting with kicks?
19) Hibarigaoka: Depression
20) Hōya: High-five
21) Ōizumi-gakuen: Dog
22) Shakujii-kōen: -
