Train45 Hot Spring Car Guide
Searches for 温泉, 温泉车辆, “Too Hot!”, and wall 54 all land here. The Hot Spring Car is Reina’s first intimacy terminal and one of the four numbers on Konial’s Memo — not a lost-item box and not the engine room.
What the Hot Spring Car Is
The Hot Spring Car is a special event terminal on Reina’s route. The hint is the Hot Spring Flyer (広告チラシ – 温泉車両). Bring Reina, queue the three cars, and you get two things: her lying-down hot-spring scene plus the Steam achievement Too Hot! (“Enjoyed a hot spring with Reina”), and the wall digit 54 used later for the engine room.
It is not required for the true ending if you already know 54 from this wiki — but first visit still raises equipment capacity (+7), and skipping it leaves a gallery hole and a missing achievement. Do not confuse it with Pazuzu’s Dark Room (2-3-10-41) or Konial’s Memo (8-31-45-54).
Unlock: Reina Lv5, Then 15-1-27
Raise Reina Takahashi to affection 5. Talk until the “hot spring” topic appears — that conversation hands you the flyer. Destinations 9–19 reject guessed codes, so do not type the cars before the flyer exists.
Queue 15-1-27 (Flooding → White residue / dripping white liquid → Fogged glass). Japanese walkthroughs write that walking order; the phone map usually accepts the same set in any order. Reina must be the companion at the door. A wrong partner fails silently — no toast, no CG, full re-queue.
| Car | Anomaly | Role |
|---|---|---|
| 15 | Flooding / submerged floor | First car in the flyer chain |
| 1 | White residue / dripping white liquid | Second car |
| 27 | Fogged / steamed glass | Third car — hot-spring door |
Unequip the Copper Bracelet first or the map is dead. Inside, read the door / wall for 54 before you leave. That is the same 54 on Konial’s Memo. Scene rules: Character Events.
After the Spring: 54, Gallery, Next Reina Beats
Write down 54. Combined with Pachinko wall 45 and the butler poster 8 / 31, the engine-room code is 8-31-45-54. Do not spend that memo until Xiao Ke OMEGA is in inventory — Engine Room.
Reina’s next flyer is the Dog Collar at affection 6 (pet car 6-17-23-28). Black Bikini (30-28-10) waits until Mai’s affection-7 event has already played, even though Reina owns the swimsuit CG. Plan those on First Playthrough.
If the CG is missing in the Event Gallery, you entered with the wrong companion or left before the scene finished. Gallery: Event Gallery.
