- What you can use
- Connects the story trigger, one-use key, and three confirmed station uses into an unlock-order decision instead of treating the key as a generic collectible.
- Confirm recipe
- Reserve materials
- Choose station
- Unlock and test
Separate the recipe unlock from the three confirmed station uses. Source basis: the references listed on this page, checked for game version 1.4. These are planning checkpoints, not measured rankings or yes/no branches. Follow the linked tables and procedures for conditions, quantities and completion checks. Not to scale; not a game map.
Scope boundary
This page is the station-by-station execution worksheet: confirm the trigger, choose one physical station, use the one-use key, and verify the new connection. It does not decide whether the recipe cost is worthwhile or whether another key should be crafted later. Use the Tram Station Key decision guide for that crafting and opportunity-cost decision.
Unlock trigger
The Tram Station Key recipe unlocks after meeting Sarah Frake and speaking to the Blacksmith. The key is crafted and consumed when used. If the recipe is missing, verify those conversations before searching for a loose key or rebuilding the Crafting Bench.
Confirmed station uses
The current key source lists three locked stations: Manufacturing West near the Digsite, the Cascade Laboratories lobby, and Power Services in Reactors. Choose the station tied to the next active objective rather than unlocking by sector age alone.
| Station | Choose it when | Delay it when |
|---|---|---|
| Manufacturing West | The Train or its connected route is next | Industrial progression is still incomplete |
| Cascade Laboratories | Laboratory travel is the current bottleneck | The save is not ready for that sector |
| Reactors Power Services | Late progression depends on that connection | Earlier routes still need their key |
Route procedure
- Confirm Sarah Frake has been met.
- Speak to the Blacksmith and verify the recipe unlock.
- Set aside one Controller and four Military Electronics, then compare the recipe materials reference below with the recipe shown in your save.
- Select one of the three documented stations.
- Craft the key, travel directly to the selected station, and use it.
- Verify the new connection before crafting another key.
Failure recovery
- The recipe is absent. Revisit the story conversations in order.
- The key was used at an unhelpful station. Record that station as open before leaving. The consumed key is no longer available for the intended lock; set aside another Controller and four Military Electronics only when replacing the key will not block the active objective. Keep using the already-open connection when it serves a later trip.
- The recipe is visible but materials are missing. Recount the Controller and Military Electronics against the table below. Gathering ingredients is a different task from unlocking the recipe; more dialogue is not a substitute for a missing component once the recipe is visible.
- The station door does not match. Confirm the location against the current key source rather than testing every locked tram door.
- The route beyond the station is unsafe. Unlocking transport does not prove the destination loadout is ready.
Completion condition
The task is complete when the recipe is visible, the chosen station is open, and the connection has been tested in both directions. Use the Manufacturing West route for the Blacksmith path or the Reactors walkthrough before committing a late-game key.
Plan the unlock as a transport project
Before spending the key, write down what the station changes. A useful answer names the destination, the task on the far side, and the return benefit. "It is the next locked station" is not enough. The Manufacturing West station supports the Train route documented by its source. The Cascade lobby station changes movement through laboratory progression. The Power Services station belongs to a much later route and should be evaluated against current Reactors objectives.
Stage the station trip separately from exploration beyond it. Carry the key, normal route protection, and enough free space for the immediate objective, but do not assume a transport unlock makes every connected area safe. On arrival, identify both platforms and test where the tram actually travels. This prevents the map from recording an imagined connection based on station names alone.
For co-op saves, tell the group which station was selected before crafting. A one-use item should not disappear into a door that only one player expected to open. If two stations are equally useful, prefer the one that removes the current shared travel bottleneck; the second key can remain a clearly named materials goal.
Record four facts after use: the station opened, the destination reached, the return worked, and the route objective changed. Those observations turn the unlock into durable navigation knowledge rather than a single successful door interaction.
Keep the three station decisions independent
Opening one station does not prove that another station is ready or useful. Manufacturing West, the Cascade Laboratories lobby, and Reactors Power Services belong to different route states. Evaluate each against the objective currently shown in the save and the hazards on the connected route.
Before a later key is crafted, review the first unlock. If it shortened a route the group actually repeats, use that result as the decision standard. If it opened transport that no current task uses, do not repeat the same reasoning at the next station. This is a progression choice, not a fixed best-to-worst tier list.
Keep the key in a named expedition slot until the selected lock is reached. The source documents that it is consumed on use, so the team should confirm the station label before interacting. Afterward, update the route note rather than leaving an obsolete "locked" marker in the base plan.
Common Mistakes
| Mistake | Why it happens | How to avoid it |
|---|---|---|
| Crafting the key before meeting Sarah Frake | Player assumes the recipe is always available | Complete both NPC conversations first; check the Crafting Bench recipe list |
| Unlocking the furthest station first | "Unlock the hardest area early" instinct | Match the key to the current active objective, not the sector difficulty |
| Using the key on the wrong tram door | Multiple locked doors look identical | Confirm the station name on the current Tram Station Key wiki page before interacting |
| No one in co-op knows which station was opened | Player crafts and uses the key without announcing it | Call out the target station before crafting; all players should agree |
| Assuming the unlocked station means the destination is safe | Transport access feels like progression completion | Scout the far platform and check enemy levels before committing supplies |
| Copying recipe materials from an outdated guide | Patch changed the crafting cost | Read the in-game recipe directly; do not trust screenshots from older versions |
| Crafting multiple keys at once without a plan | Player stockpiles keys "just in case" | Craft one key per confirmed objective; materials are better spent elsewhere until needed |
Recipe materials reference
For this guide's version 1.4 scope, one craft produces one Tram Station Key:
| Material | Quantity per key | Preparation before leaving the bench |
|---|---|---|
| Controller | 1 | Reserve one finished component; if absent, follow the Controller recipe in your save before starting the station trip |
| Military Electronics | 4 | Reserve four for this key, separate from the stock committed to other crafts; use the farming route if short |
Quantities: Tram Station Key, Recipe, cross-checked with the Japanese community wiki's recipe table on October 12, 2026. The key is a one-use item, not a reusable master key. Check the Crafting Bench if your game version or server configuration differs.
If the recipe is absent, revisit Sarah Frake and then the Blacksmith. If the recipe is present but cannot be crafted, check the ingredient counts instead. Do not treat a missing material as evidence that the dialogue failed. This table covers the final key craft, not the raw ingredients needed to manufacture a Controller or the time required to collect Military Electronics.
Pre-departure and arrival worksheet
Use one row at a time. The checkpoints are planning checks, not additional game unlock requirements or promises that a destination will be safe.
| Checkpoint | What to record in this save | Proceed only when |
|---|---|---|
| Recipe | Visible at the bench after the story conversations | You can distinguish an absent recipe from insufficient ingredients |
| Supplies | One Controller and four Military Electronics for one key | This allocation does not consume supplies reserved for the active objective |
| Destination | Manufacturing West near Digsite, Cascade Laboratories lobby, or Reactors Power Services at the far wall | The chosen lock matches the location listed in the key's Uses section |
| Arrival | Station name, key carrier, and intended connection | The group agrees before the one-use interaction |
| Return | Where the connection leads and whether the return is usable | The route has been checked instead of inferred from a sector label |
For an interrupted trip, resume from the last checkpoint actually completed. Owning the ingredients is not the same as carrying the finished key. Carrying the key is not the same as opening the selected station. Once the station is open, record that result before planning another craft; this avoids budgeting twice for the same already-completed transport task.
Co-op decision framework
In a group save, the three stations serve different progression paths. Before crafting, ask two questions: which station removes the longest current detour, and which destination has a task the group is ready for. If opinions split, pick the station that benefits the most players on the current session. The second key can wait until materials restock and the next objective is clear.
