Welcome to the balloon railway control room. A test pulse moved several switches together; the starting positions are still recorded. Your team has the original records on the table. First recover five pieces of information, then use the final plan to configure the railway switches. Keep every result beside its badge so another teammate can check your reasoning.
Find opening stock, closing stock and the DONE or CANCELLED marks.
Hint 2
Only completed entries change stock. A cancelled plan cannot be added or subtracted.
Hint 3
Apply every known completed change to opening stock. Compare that result with closing stock to recover the missing completed return.

2
Known stock: 12 + 5 - 1 = 16. Closing stock 18 minus 16 gives the missing return 2. Cancelled +7 never arrived. Result: 2.
5. Signal 5
Hint 1
Find the symbol key and the message strip.
Hint 2
Use the same key every time a symbol repeats. Read the message in its printed order.
Hint 3
Write the complete decoded word, check every symbol, then use the conversion row for that exact word.

5
The decoded word is HOME; its row gives 5. Result: 5.
6. Final
Needs: Signal, Record, Station, Stock, Signal 5
Hint 1
Find the starting states, dial order and pulse-card key.
Hint 2
Each selected vector lists turns for every dial. Several different cards can affect the same dial.
Hint 3
Add one dial column at a time to its starting state, wrap around the three-state loop, then check that all five pulse cards were used.
Reveal host answer
A1-B2-C1-D0-E0
Select one pulse card for each of the five badge results. Add the turns by dial column to the printed starting states and wrap each total around 0, 1, 2. The checked configuration is A1-B2-C1-D0-E0; each pulse pair has equal size and total turns, so its shape does not identify the correct choice.
Suggested timeline
3 minutes: Read the opening. Show the evidence record and choose starting roles.
5 minutes: Solve Signal. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Record. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Station. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Stock. Offer one hint at a time and rotate roles after checking.
5 minutes: Solve Signal 5. Offer one hint at a time and rotate roles after checking.
7 minutes: Build the checked five-dial configuration using all five results.
3 minutes: Read the ending. Ask each teammate to explain one rejected alternative.
Pause whenever the group needs a break. This is a planning estimate.
