Heathrow rail engineering works: 16 & 17 November

Due to planned engineering works, there will be no Heathrow Express or Elizabeth line services to or from Heathrow on Saturday 16 November and Sunday 17 November.

Piccadilly line services will be running as normal on both days.


Passengers should plan their journeys before travelling, and allow for additional time where necessary as trains that are running will be much busier than normal.

Documents related to workplace safety at Heathrow

To assist Property customers further to meet the Health and Safety regulations and other supporting regulations, we have made the following documents available.

The ban on works at Heathrow that break the surface is absolute. You cannot perform any surface-breaking activity – drilling, scraping, cutting or excavating – on Heathrow land without a Heathrow permit.

We keep detailed maps of Heathrow’s hidden infrastructure. When you apply for a permit, we’ll check our records and let you know whether you’re okay to dig.
Once you get your permit, you’ll know exactly where you can dig and how deep.

Heathrow is committed to being a leader in HSSE management, and in keeping security and safety the highest priority, we wish to inform our property customers of our policy on the storage, transportation and use of Acetylene and Nitrogen gas.

Unlike other pressurised cylinders acetylene gas which is used for flame cutting and welding, is extremely flammable. More importantly, fires involving acetylene cylinders require a closure of up to 24 hours due to the unstable nature of the gas during the cooling phase. The current operating protocol from the Fire Brigade is a minimum 200 meter hazard (exclusion) zone for acetylene cylinders involved in a fire, which will cause a major impact on Heathrow's operations and its passengers, potentially closing the runways. we wish to avoid a major incident involving acetylene gas and it is the intent of Heathrow to absolutely minimise the use of acetylene and to gradually phase out the storage of acetylene at the airport.

In order to reduce and control the risks outlined above, the following procedures will now apply at Heathrow airport:

  1. High risk flame cutting and welding operations should, where possible, be avoided within the airport boundary by the use of alternative techniques or by taking the work off airport.

  2. If such operations have to be carried out at the airport, alternative and more stable gases than acetylene should be used.

  3. If there are absolutely no practicable alternatives then acetylene may be used subject to the submission of an "Acetylene Justification Report" by the user and approval of such by the Heathrow Fire Safety Team. Please refer to Appendices A and B, on the following document Heathrow Instruction: Restricting the Storage and the Use of Acetylene (233KB PDF)

  4. Only sufficient acetylene should be brought onto the airport for the approved works and, where possible, acetylene cylinders should be removed from the airport on completion of those works.

  5. If acetylene has to be used on a regular basis then approval to store acetylene on the airport may also be requested via the same "Acetylene Justification Report". Any such approvals will be valid for a maximum period of one year, upon expiry of which renewed application must be made.

  6. Approval to use and/or store acetylene will only be granted where if can be demonstrated that alternative methodologies have been exhausted and high levels of control will be applied.

As part of the communications around hazardous substances, Heathrow also wishes to work with you on compressed nitrogen gas (used to inflate tyres). It is recommended that the cylinders are stored in a purpose bulit cage in a safe exterior area that us not enclosed in any way.

For further information on Heathrow's acetylene procedure please contact your Safety Adviser, the Heathrow Health and Safety Team or the Heathrow Fire Safety Team. Any deviation from this procedure must be agreed with the Head of Fire Safety for Heathrow Airport.
