Sukdeung Station Line 3 Train Specifications | Size, Capacity & Track Gauge

Sukdeung Station Line 3 Train: Basic Information

The train type serving Sukdeung Station on Line 3 is "Commuter-type DC electric multiple unit," with a track gauge (the distance between the two rails) of 1435 mm and a power supply system of DC 1,500V overhead catenary. Track gauge refers to the rail specification the train can run on, while the power supply system describes how the train draws electricity to move.

An overhead catenary system draws power through a pantograph from a contact wire above the track, while a third-rail system draws power from a separate electrified rail alongside the running rails. Because the two systems are not compatible, trains can only run through sections that share the same train type, track gauge, and power supply system.

Sukdeung Station Train Size and Capacity

The train is registered with a length of 17500 mm, a width of 2750 mm, and a height of 3600 mm. It has 8 doors (4 per side), and the body material is Stainless steel. Body material affects the vehicle’s durability and weight, and this page reports only the value recorded in the source data.

Capacity is seated 39, standing 74 for the lead car (the car at the front or rear of the train) and seated 48, standing 76 for a middle car. Lead and middle cars have different capacities because the lead car includes space for the driver’s cab. These figures combine seated and standing capacity and do not reflect real-time congestion.

Sukdeung Station Train Control, Braking, and Signalling

The speed control system is VVVF inverter control, and the braking system is Combined electric (regenerative) and pneumatic braking. VVVF inverter control adjusts speed by varying both the voltage and frequency supplied to the traction motors, while regenerative braking feeds the electrical energy generated during braking back into the power grid.

The onboard signalling system is ATP/ATO signalling system, the train information and monitoring system is TCMS, and the motor type is Induction motor. Line 3 has onboard signalling registered as ATP/ATO signalling system, and the source data does not indicate driverless operation.

Sukdeung Station: Previous and Next Stations

Sukdeung Station is stop 6 of 17 on Busan Metro Line 3, between Deokcheon Station and Namsanjeong Station.

Based on this data, Sukdeung Station only appears on this line.

Comparing Train Specifications Across Busan Metro’s 4 Lines

Line 3 shares the same track gauge (1435 mm) as Line 1/Line 2, but this differs from Line 4 (1700 mm).

The power supply system is DC 1,500V overhead catenary, which differs from the DC 750V third rail used on Line 4.

Line 3 uses a different train type (Commuter-type DC electric multiple unit) from the other lines.

Line 3 trains have 8 doors (4 per side).

How to Use This Train Specification Data at Sukdeung Station

This data covers only the vehicle’s own characteristics — specifications, capacity, and control systems — and does not include real-time train location, service intervals, time-of-day congestion, or platform screen-door availability. For live operating information or service intervals, check Busan Transportation Corporation’s official channels; if you want to avoid crowded periods, plan your trip around commuting hours.

• Keep Line 3’s track gauge and power supply (1435 mm, DC 1,500V overhead catenary) in mind when transferring to other lines
• Estimate rough capacity using the lead- and middle-car figures (seated 39, standing 74 / seated 48, standing 76)
• Use the door count (8 doors (4 per side)) to anticipate where to wait for boarding and alighting
• Since a train operator is on board, follow crew instructions in an emergency
• Check real-time schedules and delays through Busan Transportation Corporation’s official channels, not this data
