The Terminal Escape Room Morse code puzzle appears in Chapter 1: Dead End of the Roblox experience created by CCF Studios. In Standard Mode, the flashing red light in the first train carriage translates to the keypad code 3967. Entering this code into the locked door at the back of the third carriage opens the way into the cockpit.
Chapter 1 Morse Code Solution and Keypad Combination
The locked door at the end of Carriage 3 (the sleeping car) requires a four-digit numeric code to open. Above the doorway hangs a reference poster detailing how to translate Morse code into numbers.
The digits correspond to the following signals:
- 3: Dot Dot Dot Dash Dash (...--)
- 9: Dash Dash Dash Dash Dot (----.)
- 6: Dash Dot Dot Dot Dot (-....)
- 7: Dash Dash Dot Dot Dot (--...)
Entering 3967 into the keypad unlocks the door and grants access to Carriage 4, where you begin the final sequence to stop the runaway train.
How to Restore Power to the Cabin 3 Keypad
Before the door keypad accepts any input, you must restore electrical power to Carriage 3. Touching the keypad for the first time causes the breaker to trip, knocking out the cabin lighting and dropping a fuse from the electrical box next to the door.
Equip your flashlight to locate the missing fuse. The fuse spawns in different spots depending on the session:
- Under a seat in Carriage 1 (such as beneath seat B6, B9, or the rear rows)
- Under one of the blue tables in Carriage 2
- Next to the vending machine in Carriage 2
Pick up the fuse, return to Carriage 3, and place it into the open fuse box. You must then flip the ten switches to match the pattern shown on the upper walls and ceiling of Carriage 2. Setting switches 2, 5, 7, 8, and 9 to the up (active) position restores power to the train car and turns the door keypad back on.
Decoding the Cabin 1 Flashing Siren
Once the power box is active, head back through the train to Carriage 1. High on the wall near the rear of the cabin, an alarm siren blinks red in repeating intervals.
A quick flash represents a dot, while a longer illuminated burst represents a dash. A prolonged pause indicates the break between separate numbers, and an extended shutdown indicates the restart of the entire four-number loop.
The light transmits the following sequence:
- Three quick blinks followed by two long pulses (...--), which translates to the number 3.
- Four long pulses followed by one quick blink (----.), which translates to the number 9.
- One long pulse followed by four quick blinks (-....), which translates to the number 6.
- Two long pulses followed by three quick blinks (--...), which translates to the number 7.
The numbers provide the complete sequence 3967 without requiring letter translations.
Approach Comparison for Chapter 1 Carriage 3
Players tackle Carriage 3 differently depending on whether they want to practice manual codebreaking, clear the room quickly, or play on lower difficulty settings.
| Method | Scenario | Action Required |
|---|---|---|
| Standard Direct Input | Speedrunning Standard Mode | Input 3967 into the Carriage 3 keypad immediately after setting the fuse switches |
| Standard Manual Translation | Standard Mode puzzle solving | Observe the Carriage 1 red siren blinks and match them against the Carriage 3 wall chart |
| Beginner Riddle Solution | Beginner Mode playthroughs | Count neat beds, unmade beds, and blankets in Carriage 3 to calculate the code 9536 |
In Beginner Mode, the developer replaces the Morse code sequence with a four-question bed riddle. Standard Mode retains the flashing siren and electrical circuit tasks.
Other Morse Code Locations Across Terminal
While Chapter 1 contains the most recognized Morse code puzzle, the mechanic reappears in later story content. In Chapter 4: Trial and Error, buttons mounted on the left and right sides of the laboratory fume hood blink in Morse patterns. Translating the signals from left to right yields the numbers 6 and 8. These two digits form part of the multi-chapter clue chain used during the Chapter 6: Revolution secret ending puzzle, which requires an 11-digit code to unlock the final facility exit.
Frequently Asked Questions
What is the Morse code for Carriage 3 in Terminal Escape Room?
The keypad code for the Carriage 3 door in Chapter 1 Standard Mode is 3967. Players obtain this code by translating the four sequence intervals of the red flashing siren in Carriage 1 using the Morse chart above the door.
Where is the flashing red light located in Chapter 1?
The flashing light hangs high on the wall in Carriage 1, near the starting area of the train. Players must run back from Carriage 3 to observe its short and long light pulses after restoring power to the fuse box.
Does Beginner Mode use Morse code in Chapter 1?
Beginner Mode replaces the Morse code puzzle with a bed counting riddle above the Carriage 3 door. Players count neatly made beds, missing pillows, messy blankets, and bare mattresses to reach the combination 9536.
