Aerial Tramway and Cable Car Fires: NFPA 130, Kaprun 2000 and Station Zoning

Ski resorts, urban cable cars (Istanbul Eyüp–Pierre Loti, Bursa–Uludağ) and mountain aerial tramways cannot be assessed like an ordinary building; each has its own fire risks. On site, the hardest issues are combustible materials in the cabin, station smoke control and evacuating passengers stranded on the rope line. The Kaprun 2000 funicular tunnel fire (Austria, 155 dead) is the key reference event that shaped today’s NFPA 130 and EN 50126 requirements. This article walks through cable car types, the Kaprun lesson, cabin material selection and station zoning.

Cable-Car Types

• Gondola: Small cabin for 4–8 people, suspended from a single rope.
• Aerial tramway: Large cabin for 80–200 people, running back and forth on two track ropes (jig-back).
• Funicular: Rope-hauled railway on a slope (the Kaprun type).
• Chair lift: Open seats; with no combustible material, fire risk is close to zero.
• Cable car: Generic term covering all rope-hauled transport systems.

Kaprun 2000 Lesson

• Event: Fire in the funicular tunnel on the Kitzsteinhorn.
• Fatalities: 155; the worst single accident in Austrian history.
• Cause: A faulty fan heater ignited hydraulic oil that had leaked onto it.
• Escape: Smoke flowed up the tunnel, and passengers fled upward in the same direction as the smoke.
• Lesson: In an inclined tunnel fire the correct escape direction is downhill, because hot smoke flows upward; the evacuation plan must be based on this.

Cabin Material Properties

• Structure: Aluminum or composite shell; low external fire load.
• Interior trim: Flame-retardant (FR) polyester; EN 13501 class C-s2,d0 is targeted.
• Windows: Polycarbonate panels; for impact we prefer UL 752 certified material.
• Electrical: 24 V battery; fuses and isolators against short circuits are critical.
• Static electricity: Static charge on the ropes must be continuously discharged through an earthing line.

Station Smoke Control

• NFPA 130: The station must be fully evacuable within 6 minutes.
• Smoke extraction: Fire smoke is exhausted directly outside by fans above the line.
• Sprinklers: Priority on the station machinery room, with its concentration of oil and electrical equipment.
• Cabin rescue: Evacuation towers at roughly 100 m intervals along the line.
• Rope rescue: A rappel kit for trained staff kept ready at every station.

Turkish Examples

• Istanbul Eyüp–Pierre Loti: Urban cable car with an 800 m line.
• Bursa cable car: At 8.2 km, one of the longest lines in the world.
• Uludağ: Ski resort; fires are rare in winter, but electrical faults are the main risk.
• Kartalkaya: The January 2025 hotel fire was not related to the cable car, but it put fire safety culture in the region’s resorts back on the agenda.
• Maintenance: Annual inspection under TS EN 1709 is mandatory.
