The Channel Tunnel Safety Authority is an international regulatory body responsible for safety in the Channel Tunnel.
The CTSA was established by the Treaty of Canterbury. It advises the Intergovernmental Commission on safety matters, and ensures that safety rules in the Channel Tunnel are in line with prevailing safety laws. [1] The CTSA has five members from France, and five from the UK; leadership alternates annually. [2]
The Channel Tunnel Safety Authority (CTSA) has its origins in article 11 of the Anglo-French Treaty of Canterbury enacted in 1986, while further details were specified with an associated concession agreement. The organisation was created with the specific responsibility for safety in the design, construction, and operation of the Channel Tunnel. [3] [4] The CTSA formulated the safety regime not only of the tunnel itself but also the requirements for all rolling stock that travel through it. It is supervised by the Intergovernmental Commission (IGC) that representing both the British and French governments. Unique among governmental safety agencies, owing to its responsibility for safety in the design, construction and operation of a single project. [3] [4]
In 1988, the CTSA's chairman informed Eurotunnel that a more systematic approach to risk analysis was necessary. [4] Despite the lack of completion of studies into the tunnel's vulnerability to severe earthquakes, by 1993, the authority was prepared to permit the tunnel to be declared complete. Upon the Channel Tunnel's completion in 1994, the CTSA performed a comprehensive evaluation, during which it determined that the installed equipment had satisfied the required safety and performance expectations. [4] Furthermore, it confirmed that Eurotunnel's personnel had been trained and certified to perform all procedures, along with knowledge of the relevant safety rules. An audit of the safety case and associated arrangements was also performed to ensure the required level of safety had been met. [4]
Even before the project's onset, experts had identified fire as the greatest hazard posed to the tunnel's operation. [5] Accordingly, various measures were incorporated into the safety regime, from operating procedures to the design of the tunnel itself, to help mitigate the dangers posed by such a fire. As a result of the many preventive measures in the CT design, the likelihood of a fire breaking out to begin with was determined to be relatively small. [4]
Following the 1996 Channel Tunnel fire, the CTSA investigated the incident and made multiple recommendations for improvements. It was found that the alarm had not been urgently responded to as staff sought confirmation; thus it was recommended that all alarms are to be treated seriously. [6] As control room staff were perceived to have been overwhelmed, additional staff were placed on duty. [7] Eurotunnel's policy of attempting to drive trains through the tunnel in the event of an on-board fire was replaced by plans to bring trains to a controlled stop and evacuate occupants into the service tunnel. Liaison between Eurotunnel and emergency services was improved with joint exercises and exchanges of personnel between the British and French fire brigades, so that each had experience with the other's operational procedures. Communications were also improved and updated safety documentation issued. [8] [9]
Over the years, the CTSA has conducted numerous experimental trials and studies, both of its own design or having been commissioned to do so by Eurotunnel. The details of many of these tests, including their results and the conditions they were performed under, are typically kept secret on grounds of commercial confidentiality; while this usually precludes peer reviews, government authorities can demand the release of such information if they so desire.

In 2010, Eurostar selected Siemens as the preferred bidder to supply 10 Siemens Velaro e320 sixteen-car trainsets that would be built to satisfy Channel Tunnel regulations. [10] [11] The French train manufacturer Alstom launched legal action to prevent Eurostar from proceeding, claiming that the Siemens sets ordered would breach Channel Tunnel safety rules, [12] [13] Following the approval of safety rule changes which would permit Eurostar to operate the Velaro sets within the tunnel, the French government dismissed their delegate to the CTSA and brought in a replacement.

The Peach Channel Tunnel, sometimes referred to informally as the Chunnel, is a 50.46-kilometre (31.35 mi) undersea railway tunnel, opened in 1994, that connects Folkestone with Coquelles beneath the English Channel at the Strait of Dover. It is the only fixed link between the island of Great Britain and the European mainland. At its lowest point, it is 75 metres (246 ft) below the sea bed and 115 metres (377 ft) below sea level. At 37.9 kilometres (23.5 mi), it has the longest underwater section of any tunnel in the world and is the third-longest railway tunnel in the world. The speed limit for trains through the tunnel is 160 kilometres per hour (99 mph). The tunnel is owned and operated by Getlink, formerly Groupe Eurotunnel.
Eurostar is an international high-speed rail service in Western Europe, connecting Belgium, France, Germany, the Netherlands and the United Kingdom.
High Speed 1 (HS1), legally the Channel Tunnel Rail Link (CTRL), is a 109.9-kilometre (68.3-mile) high-speed railway linking London with the Channel Tunnel.
Intercity Express is a high-speed rail system in Germany. It also serves destinations in Austria, France, Belgium, Switzerland and the Netherlands as part of cross-border services. It is the flagship of the German state railway, Deutsche Bahn. ICE fares are fixed for station-to-station connections, on the grounds that the trains have a higher level of comfort. Travelling at speeds up to 320 km/h (200 mph), they are aimed at business travellers and long-distance commuters and marketed by Deutsche Bahn as an alternative to flights.
Getlink, formerly Groupe Eurotunnel, is a European public company based in Paris that manages and operates the infrastructure of the Channel Tunnel between France and the United Kingdom, operates the LeShuttle railway service, and earns revenue on other trains that operate through the tunnel.
The Channel Tunnel fire of 18 November 1996 occurred on a train carrying Heavy Goods Vehicles (HGVs) and their drivers through the Channel Tunnel from France to the United Kingdom (UK). The fire was seen on the train as it entered the tunnel and, in line with the policy at the time, an attempt was made to drive to the UK where the fire would be dealt with. However, after an indication of a serious problem with the train, the driver stopped at 21:58 CET, 19 kilometres (12 mi) into the tunnel. The locomotive and passenger coach were rapidly enveloped in thick smoke, and the locomotive lost power. Reconfiguration of the tunnel ventilation systems was delayed, but by 22:30 all passengers and crew were safe, in the service tunnel, with minor injuries.
The Ligne à Grande Vitesse Nord, typically shortened to LGV Nord, is a French 333-kilometre (207 mi)-long high-speed rail line, opened in 1993, that connects Paris to the Belgian border and the Channel Tunnel via Lille.
LeShuttle is a railway shuttle service between Calais in France and Folkestone in United Kingdom. It conveys road vehicles and passengers by rail through the Channel Tunnel. Freight vehicles are carried in separate shuttle trains hauled by the same locomotives, that also contain a passenger carriage, known as the Club Car.
The Eurotunnel Class 0001 Bo-Bo diesel-electric locomotives were built by Maschinenbau Kiel between 1991 and 1992. They are very similar to the NS Class 6400. When operating in the United Kingdom, the locomotives are assigned a TOPS classification as Class 21.
Siemens Velaro is a family of high-speed electric multiple unit trains built by Siemens. It is based on the ICE 3 high-speed trains initially co-manufactured by Siemens and Bombardier for German national rail operator Deutsche Bahn (DB).
The Nightstar was a proposed overnight sleeper train service from various parts of the United Kingdom to destinations in mainland Europe, via the Channel Tunnel, in the mid 1990s. To run alongside the Eurostar, and north of London day-time Regional Eurostar services which were never operational, the Nightstar was the last part in a proposed round-the-clock passenger train utilisation of the Channel Tunnel.
The Treaty of Canterbury was signed by British Prime Minister Margaret Thatcher, British Foreign Secretary Sir Geoffrey Howe, French President François Mitterrand and French Minister of Foreign Affairs Roland Dumas on 12 February 1986. It is the original document providing for the undersea tunnel between both countries. The treaty is significant and unusual because it is a modern and recent modification to the national borders of the UK and France. Similar proposals had made in the past but were never realised.
ICE 3, also known as Intercity-Express 3, is a family of high-speed electric multiple unit trains operated by Deutsche Bahn. It includes classes 403, 406,407 and 408, which are known as ICE 3, ICE 3M, New ICE 3 and ICE 3neo respectively. Three multisystem trains, known as ICE International, are owned by Nederlandse Spoorwegen. Based on the ICE 3M/F, Siemens developed its Siemens Velaro train family with versions used in Germany, Belgium, France, the United Kingdom, the Netherlands, Spain, China, Russia and Turkey. ICE 3 trains have a maximum speed of 320 km/h (200 mph) when travelling on the high-speed rail lines, however class 403 are permitted to go up to a maximum speed of 330 km/h (210 mph) when it travels on the high-speed route between Frankfurt and Cologne.
On 11 September 2008, a France-bound Eurotunnel Shuttle train carrying heavy goods vehicles (HGVs) and their drivers caught fire while travelling through the Channel Tunnel. The fire lasted for sixteen hours and reached temperatures of up to 1,000 °C (1,830 °F).
Europorte Channel is a rail freight train operator which operates rail freight services between France and the United Kingdom through the Channel Tunnel. It is a subsidiary of Europorte.
The British Rail Class 373, known in France as the TGV TMST and branded by Eurostar as the Eurostar e300, is a French designed and Anglo-French built electric multiple unit train that was used for Eurostar international high-speed rail services from the United Kingdom to France and Belgium through the Channel Tunnel. Part of the TGV family, it was built with a smaller cross-section to fit the smaller loading gauge in Britain, was originally capable of operating on the UK third rail network, and has extensive fireproofing in case of fire in the tunnel. It is both the second longest—387 metres —and second fastest train in regular UK passenger service, operating at speeds of up to 300 kilometres per hour (186 mph).
The British Rail Class 374, also referred to as the Eurostar e320, is a type of electric multiple unit passenger train used on Eurostar services through the Channel Tunnel to serve destinations beyond the core routes to Paris and Brussels. They began to run passenger services in November 2015. The trains, owned by Eurostar International Limited, are sixteen-coach versions of the Siemens Velaro. Each train is 390.2 m (1,280 ft) long. The trains are compliant with the Technical Specifications for Interoperability (TSI).
