How to Unlock the Train45 Gallery & Memory Room

What the Gallery Actually Contains

The Train45 gallery in the main menu holds three sub-menus:

• CG Gallery — every scene frame from the base game plus the Artbook DLC. Unlocks per companion after their event window closes.
• Memory Room (回想 / 回忆房) — high-resolution scene replays that include the Black Bikini, Hot Spring, Pet Car, and Mai's bunny-girl scenes. Replays use the in-engine models, not static CG.
• Ghost H (幽霊H) — a single rare scene frame unlocked only by finishing the route with the X-Ray Spec equipped. This is the rarest gallery item — Steam Hunters tracks it at roughly 52% global unlock rate.

The gallery is not visible at all until you finish the game once. Save-data carry-over rules apply on subsequent playthroughs.

Why the Gallery Does Not Appear

Steam Community threads repeatedly surface this exact problem. Three causes account for 90% of "where is the gallery?" reports:

1. The save is on an unfinished slot. The gallery only attaches to a save with an ending record. Pick a save file that has any ending — Good, Bad, Destined, or True — and the menu entry unlocks on next launch.
2. Demo save carry-over failed. v1.0.4.2 broke demo-to-full carry-over, so Demo saves do not propagate gallery unlocks to the full release. Delete Demo saves from %USERPROFILE%\AppData\Roaming\TrainNumber45\ before launching the full game.
3. The memory-room trigger was never fired. The Memory Room only unlocks after the True Ending route 8-31-45-54 with Xiao Ke OMEGA equipped. Bad endings and the Destined End do not trigger it.

If none of the above apply, verify your build: the public branch has carried gallery content since v1.0.4.2 (14 July 2026).

Step-by-Step Unlock

Follow this sequence on a fresh or rolled save:

1. Finish a single run that ends on any ending. The simplest path is the Reina Happy Ending — her finale branch is reachable in roughly 4 hours with the Affinity Tracker keeping Lv7 on schedule.
2. After the ending screen, let the credits roll and choose "Return to Title" — do not close the launcher.
3. On the title screen, the gallery entry appears bottom-left. It shows three locked icons if you have not done True Ending.
4. To unlock the Memory Room scenes: complete the True Ending route. Equip the Copper Bracelet, raise Konial to Lv2, watch her Lv1 affection dialogue, then queue 8-31-45-54 with Xiao Ke OMEGA in your inventory. Spend the Memo on the engine room lever. The Memory Room unlocks on the credits roll.
5. For Ghost H: keep the X-Ray Spec equipped from chapter 4 onward. The scene triggers automatically during Konial's finale if you have not unequipped the spec since OMEGA.

Save data persists across Steam Cloud, so the gallery unlocks sync between desktop, laptop, and Steam Deck.

Save File Carry-Over Rules

Train45 cloud-saves gallery unlocks but only if the Steam Cloud channel is active. The save root is:

• Windows: %USERPROFILE%\AppData\Roaming\TrainNumber45\
• Steam Cloud path: 3711590\remote\save_N.sav
• Steam Deck (Linux prefix): ~/.steam/steam/steamapps/compatdata/3711590/pfx/drive_c/users/steamuser/AppData/Roaming/TrainNumber45/

Backing up the entire TrainNumber45 folder before a True Ending attempt is the safest way to keep gallery progress. Our Save Files guide covers the full Steam Cloud procedure and the v1.0.5.1 sync behaviour.

What Each Gallery Sub-Menu Shows

Steam Hunters lists the "Became friends with the ghosts" achievement at 60.56% (74 of 148 club members) and the "Twisted causality" achievement at 52.68% (86 of 148) — both are gallery-locked and represent the long-tail content.

Common Mistakes

• Closing the launcher before credits. The gallery is committed to the save during the credits roll. Hard-closing breaks the trigger.
• Equipping the X-Ray Spec after OMEGA. Ghost H requires the spec to be on at the moment of the finale dialogue — putting it on later does not retroactively unlock the frame.
• Skipping a true-ending carry-over. Demo saves are still flagged as Demo until you delete them. Full-release saves never inherit gallery unlocks from a Demo slot.
