Appendix 2 - ERA

RULE BASIS FOR ITEMS DESCRIBED IN THE IGC CONSULTATION LETTERS
ON SPECIFIC CHANNEL TUNNEL SAFETY RULES
i. Continued Running of a train that is on fire for 30 minutes
The document "List of Standards and technical specifications for Interoperability for
the Channel Tunnel" includes the following notified to the Commission in January
2009 and hereafter referred “LSTS”:
See IV - ROLLING STOCK
4.1.2. - "A fire detection/action/extinguishing system shall be designed to allow the
locomotive to continue travelling and protect the driver for at least 30 minutes in
the event of fire."
See also 4.3 Passenger Trains
4.3.6.3
“Motor compartment partitions shall remain smoke-tight for at least 30 minutes.”
and 4.3.6.4
“Structural devices shall be planned to protect rigid pipework and hose and vital
cabling and appliances against fire for a duration in the order of 30 minutes.”
See also Network Statement Appendix 2 Article 2.7
“A sufficient number of fire barriers must be installed at the ends of some vehicles
to safeguard all passengers and staff as they evacuate the train towards the
service tunnel or during the exit of the train from the service tunnel in the event of
an emergency, for at least 30 minutes.
The traction compartment partitions must remain fire-resistant and smoke-tight
during the exit of the train from the tunnel in the event of an emergency, for at least
30 minutes.
Construction details must afford 30 minutes fre protectionfor pipes and hoses and
wiring and equipment during the exit of the train from the tunnel in the event of an
emergency, for at least 30 minutes.”
There is a statement in the Concession Agreement (Annexe 1 - AI 55.4) where
these obligations are clearly stated for the Shuttle trains. Even though they are
not specifically mentioned, an equivalent level of safety is expected from and for

the other passenger trains. Hence the mention of equivalent specifications in the
Submission to the IGC for TransManche Super Trains (TMST) :
- Submission to the IGC (IGC 10/01/003) from 27/07/1989 - Point 2.3.3
"Precautions against fire".
- Submission to the IGC (IGC 10/01/025) from 02/03/1993 - Point 3.6 "Fire
precautions" (additional points).
The Avant-Projet 12 - "Shuttle trains - Tourist wagons", in line with the
Concession Agreement requirements, describes the design and equipment in
place to allow the safe 30 minutes running out of the tunnel, for shuttles.
ii. Traction requirements
See LSTS III - Track and gauges.
Article 3.1.1
See LSTS 4.3 Passenger Trains
4.3.4.1 (where the requirement quoted in the IGC letter appears)
« Electric locomotives shall be ... able :
* to traverse maximum inclines of 11 per thousand;
* to remove a train of the same type in distress from the tunnel
* and to evacuate its own train from the tunnel from a standstill, 50% of its tractive
performance available.”
Network Statement Appendix 2 Article 2.5
iii. Traction Systems and Extinction of Fires in Traction Units (Distributed
Power)
Traction system
The requirement for a locomotive at each end is from Article A1 (55) (ii) of the
Concession Agreement, though LSTS 4.3. Passenger Trains mentions “motors
units” which concerns units with a locomotive at each end as well as units with
distributed power.
Article A1 (55) (ii) states:
“Except where operating rules otherwise permit, all trains shall be equipped with
two locomotives, one situated at the head and the other at the rear of the train.”
Extinction of fires
See i)
iv. Smoke Penetration Systems and Door Joints
The Concession Agreement requires an Avant Projet to be agreed by the IGC for
all aspects of the construction and operation of the tunnel. The avant projets
relating to the design of passenger rolling stock included highly specific features,
such as for the design of these systems. The intention of the IGC was to indicate
that it would no longer insist on such a specific requirement.

v. and vi. Minimum Length of Trains / Multiple Units
The Concession Agreement requires an Avant Projet to be agreed by the IGC for
all aspects of the construction and operation of the tunnel. The avant projets
relating to the design of passenger rolling stock included the requirement
described in the IGC letter concerning length of train and through corridor – that
the train should normally be at least 375 metres long and have a through corridor.
Network Statements prior to the 2012 statement included this provision.
vii. Splittability
The requirement is from Article A1 (55) (ii) of the Concession Agreement. This
states “Except where operating rules otherwise permit, all trains shall be equipped
with two locomotives, one situated at the head and one at the rear of the train
enabling the train to be split and to reverse direction.”
viii. Electric Traction
See LSTS 3.3 Electricity supply
3.3.1 Locomotives shall conform to standard EN 50136
See LSTS IV - ROLLING STOCK
4.1 - The locomotives
4.1.1 - Traction
"Only traffic hauled by electric locomotives shall be admitted to the tunnel."
ix. Fire Protection Standards for the Design of Vehicles and their Fittings
Article A 1.6 of the Concession Agreement. The Avant Projets for the rolling stock
specify only French standards.
x. Call Buttons at the End of Each Coach
The Concession Agreement requires an Avant Projet to be agreed by the IGC for
all aspects of the construction and operation of the tunnel. The avant projets
relating to the design of passenger rolling stock included highly specific features,
such as for the design of these systems. The intention of the IGC was to indicate
that this would no longer be such a specific requirement. The current requirements
as described and agreed in the relevant avant projet are described in detail in the
IGC’s letter with a comparison to the TSI.
