Code for Design of Emergency Evacuation and
Rescue Works for Railway Tunnel
Issued on May 14,2018
Issued by National Railway Administration of the People’s Republic of China
1 General Provisions
1.0.1 This Code is prepared with a view to implementing the laws and regulations concerning safe
production and safe railway transportation, guaranteeing the safe evacuation and rescue of persons in of accidents such as trains catching fire in tunnel, standardizing the design of emergency
and rescue works for railway tunnel and rendering the emergency evacuation and works for railway tunnel safe, technically advanced, and cost effective.
1.0.2 This Code is applicable to the design of emergency evacuation and rescue works for tunnels on
high-speed railways, intercity railways, and mixed passenger and freight railways.
1.0.3 The principle of “people orientation, safe evacuation, emphasis on self-rescue, and convenience shall be followed in the design of emergency evacuation and rescue works for railway
tunnel.
1.0.4 In case the train catches fire in tunnel, it shall run out of the tunnel for evacuation. If the train
cannot run out of the tunnel, it shall stop at the emergency rescue station for evacuation and rescue.
1.0.5 For the design of emergency evacuation and rescue works for railway tunnel, the overall
scheme design shall be intensified and the interface design shall be coordinated so as to ensure the
working functions.
1.0.6 In addition to this Code, the design of emergency evacuation and tunnel shall also comply with relevant current standards of China.
3 Basic Requirements
3.0.1 The overall scheme design of emergency evacuation and works for railway tunnel shall
be carried out in consideration of the technical standards, works distribution, works features,
rescue environment, and operational mode of the railway line.
3.0.2 Evacuation outside the tunnel shall be preferred to that inside the tunnel. The route and
facilities for evacuation shall be designed in consideration of the transportation property, environment, construction adit etc.
3.0.3 The emergency train on fire stops. The emergency exit, refuge adit and persons evacuation in case of train accident.
3.0.4 Through evacuation passage(s) shall be provided in the tunnel, with single passage provided
side in single-track tunnel, double passages provided on both sides in multiple-track tunnel.
3.0.5 Emergency rescue station(s) shall be provided for a tunnel or a tunnel group with a length of
20 km or above.
3.0.6 For single-tube tunnels with a length of 10 km or above, at least one emergency exit or refuge
adit shall be provided at tunnel body.
3.0.7 For single-tube tunnels with a length not less than 5 km but less than 10 km, one emergency
exit or refuge adit should be provided at tunnel body considering the construction adit.
3.0.8 For two parallel tunnel tubes serving as rescue and evacuation passages for each other.
3.0.9 For tunnels provided with emergency rescue station, the arrangement of the emergency exit,
refuge adit and cross passage shall comply with the requirements of Articles 3.0.6〜 3.0.8 of this
Code.
3.0.10 The structure, waterproofing and drainage of civil works for emergency evacuation and
shall be designed as required by permanent works. The floor of the passages for evacuation shall be
flat, stable, and free of ponding.
3.0.11 The emergency rescue station at the tunnel portal and the portal of the emergency exit should be provided with temporary refuge site.
3.0.12 The design fire scale of tunnels shall be determined by assuming that for one tunnel or one
tunnel group, only one car of a passenger train is on fire at a certain time. The fire scale shall be
determined by the types of the trains operating on the railway line. 15 MW may be assumed for EMU, 20 MW for conventional passenger trains.
3.0.13 The principle of separating persons from smoke shall be followed in emergency ventilation
design.
3.0.14 The safe persons evacuation time shall comply with the following requirements.
1 The available evacuation time shall be longer than the required evacuation time.
2 The required evacuation time for the emergency rescue station in tunnel should not exceed 6 miru
3. 0.15 The design of emergency evacuation and rescue works shall include the following main items.
1 Overall scheme design. type, scale and quantity of emergency evacuation and works.
4 Civil Works
4.1 General Requirements

communication, signalling, buildings, water supply and drainage, mechanic system, etc.
4.1.2 The emergency specific conditions of the tunnel or tunnel group.
4.1.3 When a railway station is arranged in the tunnel or tunnel group, the emergency evacuation
