We and our 922 advertising partners process your personal data using technology such as cookies in order to serve advertising, analyse our traffic and deliver customised experiences for you. You have a choice in who uses your data and for what purposes.
Some partners do not ask for your consent to process your data, instead, they rely on their legitimate business interest. View our list of partners to see the purposes they believe they have legitimate interest for and how you can object to it.
The Consent Signal (TC String) is stored in the Local Storage with a maximum retention period of 13 months, after which a renewed consent decision is required. Find out more about how your personal data is processed and set your preferences below.
You can set your consent preferences and determine how you want your data to be used based on the purposes below. Each purpose has a description so that you know how we and our partners use your data.
Cookies, device or similar online identifiers (e.g. login-based identifiers, randomly assigned identifiers, network based identifiers) together with other information (e.g. browser type and information, language, screen size, supported technologies etc.) can be stored or read on your device to recognise it each time it connects to an app or to a website, for one or several of the purposes presented here.
Examples:
Most purposes explained in this notice rely on the storage or accessing of information from your device when you use an app or visit a website. For example, a vendor or publisher might need to store a cookie on your device during your first visit on a website, to be able to recognise your device during your next visits (by accessing this cookie each time).

Advertising presented to you on this service can be based on limited data, such as the website or app you are using, your non-precise location, your device type or which content you are (or have been) interacting with (for example, to limit the number of times an ad is presented to you).
Examples:
A car manufacturer wants to promote its electric vehicles to environmentally conscious users living in the city after office hours. The advertising is presented on a page with related content (such as an article on climate change actions) after 6:30 p.m. to users whose non-precise location suggests that they are in an urban zone.
A large producer of watercolour paints wants to carry out an online advertising campaign for its latest watercolour range, diversifying its audience to reach as many amateur and professional artists as possible and avoiding showing the ad next to mismatched content (for instance, articles about how to paint your house). The number of times that the ad has been presented to you is detected and limited, to avoid presenting it too often.
Vendors 662
Information about your activity on this service (such as forms you submit, content you look at) can be stored and combined with other information about you (for example, information from your previous activity on this service and other websites or apps) or similar users. This is then used to build or improve a profile about you (that might include possible interests and personal aspects). Your profile can be used (also later) to present advertising that appears more relevant based on your possible interests by this and other entities.
Examples:
If you read several articles about the best bike accessories to buy, this information could be used to create a profile about your interest in bike accessories. Such a profile may be used or improved later on, on the same or a different website or app to present you with advertising for a particular bike accessory brand. If you also look at a configurator for a vehicle on a luxury car manufacturer website, this information could be combined with your interest in bikes to refine your profile and make an assumption that you are interested in luxury cycling gear.
An apparel company wishes to promote its new line of high-end baby clothes. It gets in touch with an agency that has a network of clients with high income customers (such as high-end supermarkets) and asks the agency to create profiles of young parents or couples who can be assumed to be wealthy and to have a new child, so that these can later be used to present advertising within partner apps based on those profiles.
Vendors 531
Advertising presented to you on this service can be based on your advertising profiles, which can reflect your activity on this service or other websites or apps (like the forms you submit, content you look at), possible interests and personal aspects.
Examples:
An online retailer wants to advertise a limited sale on running shoes. It wants to target advertising to users who previously looked at running shoes on its mobile app. Tracking technologies might be used to recognise that you have previously used the mobile app to consult running shoes, in order to present you with the corresponding advertisement on the app.
A profile created for personalised advertising in relation to a person having searched for bike accessories on a website can be used to present the relevant advertisement for bike accessories on a mobile app of another organisation.
Vendors 528
Information about your activity on this service (for instance, forms you submit, non-advertising content you look at) can be stored and combined with other information about you (such as your previous activity on this service or other websites or apps) or similar users. This is then used to build or improve a profile about you (which might for example include possible interests and personal aspects). Your profile can be used (also later) to present content that appears more relevant based on your possible interests, such as by adapting the order in which content is shown to you, so that it is even easier for you to find content that matches your interests.
Examples:
You read several articles on how to build a treehouse on a social media platform. This information might be added to a profile to mark your interest in content related to outdoors as well as do-it-yourself guides (with the objective of allowing the personalisation of content, so that for example you are presented with more blog posts and articles on treehouses and wood cabins in the future).
You have viewed three videos on space exploration across different TV apps. An unrelated news platform with which you have had no contact builds a profile based on that viewing behaviour, marking space exploration as a topic of possible interest for other videos.
Vendors 236
Content presented to you on this service can be based on your content personalisation profiles, which can reflect your activity on this or other services (for instance, the forms you submit, content you look at), possible interests and personal aspects. This can for example be used to adapt the order in which content is shown to you, so that it is even easier for you to find (non-advertising) content that matches your interests.
Examples:
You read articles on vegetarian food on a social media platform and then use the cooking app of an unrelated company. The profile built about you on the social media platform will be used to present you vegetarian recipes on the welcome screen of the cooking app.
You have viewed three videos about rowing across different websites. An unrelated video sharing platform will recommend five other videos on rowing that may be of interest to you when you use your TV app, based on a profile built about you when you visited those different websites to watch online videos.
Vendors 210
Information regarding which advertising is presented to you and how you interact with it can be used to determine how well an advert has worked for you or other users and whether the goals of the advertising were reached. For instance, whether you saw an ad, whether you clicked on it, whether it led you to buy a product or visit a website, etc. This is very helpful to understand the relevance of advertising campaigns.
Examples:
You have clicked on an advertisement about a “black Friday” discount by an online shop on the website of a publisher and purchased a product. Your click will be linked to this purchase. Your interaction and that of other users will be measured to know how many clicks on the ad led to a purchase.
You are one of very few to have clicked on an advertisement about an “international appreciation day” discount by an online gift shop within the app of a publisher. The publisher wants to have reports to understand how often a specific ad placement within the app, and notably the “international appreciation day” ad, has been viewed or clicked by you and other users, in order to help the publisher and its partners (such as agencies) optimise ad placements.
Vendors 771
Information regarding which content is presented to you and how you interact with it can be used to determine whether the (non-advertising) content e.g. reached its intended audience and matched your interests. For instance, whether you read an article, watch a video, listen to a podcast or look at a product description, how long you spent on this service and the web pages you visit etc. This is very helpful to understand the relevance of (non-advertising) content that is shown to you.
Examples:
You have read a blog post about hiking on a mobile app of a publisher and followed a link to a recommended and related post. Your interactions will be recorded as showing that the initial hiking post was useful to you and that it was successful in interesting you in the related post. This will be measured to know whether to produce more posts on hiking in the future and where to place them on the home screen of the mobile app.
You were presented a video on fashion trends, but you and several other users stopped watching after 30 seconds. This information is then used to evaluate the right length of future videos on fashion trends.
Vendors 384
Reports can be generated based on the combination of data sets (like user profiles, statistics, market research, analytics data) regarding your interactions and those of other users with advertising or (non-advertising) content to identify common characteristics (for instance, to determine which target audiences are more receptive to an ad campaign or to certain contents).
Examples:
The owner of an online bookstore wants commercial reporting showing the proportion of visitors who consulted and left its site without buying, or consulted and bought the last celebrity autobiography of the month, as well as the average age and the male/female distribution of each category. Data relating to your navigation on its site and to your personal characteristics is then used and combined with other such data to produce these statistics.
An advertiser wants to better understand the type of audience interacting with its adverts. It calls upon a research institute to compare the characteristics of users who interacted with the ad with typical attributes of users of similar platforms, across different devices. This comparison reveals to the advertiser that its ad audience is mainly accessing the adverts through mobile devices and is likely in the 45-60 age range.

Information about your activity on this service, such as your interaction with ads or content, can be very helpful to improve products and services and to build new products and services based on user interactions, the type of audience, etc. This specific purpose does not include the development or improvement of user profiles and identifiers.
Examples:
A technology platform working with a social media provider notices a growth in mobile app users, and sees based on their profiles that many of them are connecting through mobile connections. It uses a new technology to deliver ads that are formatted for mobile devices and that are low-bandwidth, to improve their performance.
An advertiser is looking for a way to display ads on a new type of consumer device. It collects information regarding the way users interact with this new kind of device to determine whether it can build a new mechanism for displaying advertising on this type of device.
Vendors 574
Content presented to you on this service can be based on limited data, such as the website or app you are using, your non-precise location, your device type, or which content you are (or have been) interacting with (for example, to limit the number of times a video or an article is presented to you).
Examples:
A travel magazine has published an article on its website about the new online courses proposed by a language school, to improve travelling experiences abroad. The school’s blog posts are inserted directly at the bottom of the page, and selected on the basis of your non-precise location (for instance, blog posts explaining the course curriculum for different languages than the language of the country you are situated in).
A sports news mobile app has started a new section of articles covering the most recent football games. Each article includes videos hosted by a separate streaming platform showcasing the highlights of each match. If you fast-forward a video, this information may be used to select a shorter video to play next.

Special Purposes
Your data can be used to monitor for and prevent unusual and possibly fraudulent activity (for example, regarding advertising, ad clicks by bots), and ensure systems and processes work properly and securely. It can also be used to correct any problems you, the publisher or the advertiser may encounter in the delivery of content and ads and in your interaction with them.
Examples:
An advertising intermediary delivers ads from various advertisers to its network of partnering websites. It notices a large increase in clicks on ads relating to one advertiser, and uses data regarding the source of the clicks to determine that 80% of the clicks come from bots rather than humans.
Certain information (like an IP address or device capabilities) is used to ensure the technical compatibility of the content or advertising, and to facilitate the transmission of the content or ad to your device.
Examples:
Clicking on a link in an article might normally send you to another page or part of the article. To achieve this, 1°) your browser sends a request to a server linked to the website, 2°) the server answers back (“here is the article you asked for”), using technical information automatically included in the request sent by your device, to properly display the information / images that are part of the article you asked for. Technically, such exchange of information is necessary to deliver the content that appears on your screen.
The choices you make regarding the purposes and entities listed in this notice are saved and made available to those entities in the form of digital signals (such as a string of characters). This is necessary in order to enable both this service and those entities to respect such choices.
Examples:
When you visit a website and are offered a choice between consenting to the use of profiles for personalised advertising or not consenting, the choice you make is saved and made available to advertising providers, so that advertising presented to you respects that choice.
Features
Information about your activity on this service may be matched and combined with other information relating to you and originating from various sources (for instance your activity on a separate online service, your use of a loyalty card in-store, or your answers to a survey), in support of the purposes explained in this notice.
In support of the purposes explained in this notice, your device might be considered as likely linked to other devices that belong to you or your household (for instance because you are logged in to the same service on both your phone and your computer, or because you may use the same Internet connection on both devices).
Your device might be distinguished from other devices based on information it automatically sends when accessing the Internet (for instance, the IP address of your Internet connection or the type of browser you are using) in support of the purposes exposed in this notice.
With your acceptance, your precise location (within a radius of less than 500 metres) may be used in support of the purposes explained in this notice.
With your acceptance, certain characteristics specific to your device might be requested and used to distinguish it from other devices (such as the installed fonts or plugins, the resolution of your screen) in support of the purposes explained in this notice.

We answered
TfL Ref: FOI-2221-2425
Thank you for your request received by Transport for London (TfL) on 12th October 2024.
Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.
Specifically you asked:
“I would like to request the following information regarding passenger emergency alarms and ramp usage across all lines and rolling stock:
Passenger Emergency Alarms:
1. The location of the passenger emergency alarms on trains.
2. The height of the passenger emergency alarms from the train floor.
3. The number of times the emergency alarm was activated in 2023 due to mobility aid users being unable to deboard at their destination.
Ramp and Mini Ramp Usage Statistics:
1. The number of times a ramp or mini ramp was requested in 2023.
2. The number of instances where a requested ramp or mini ramp was not available for a mobility aid user at their destination in 2023.”
I can confirm that we hold some of the information you require.
In answer to Questions 1 and 2 on Passenger Emergency Alarms (PEAs), the information is as follows:
Elizabeth Line:
PEAs are located at doorways A, C and E on every saloon and Call For Aid (CAF) points are located in the wheelchair bays. This is further illustrated in the attached diagrams (PEAs are shown as red dots, CAF points are green dots).
The PEA height is 1390mm, the CFA height is 750mm
London Underground:
We have different rolling stock in use across different London Underground lines. There is a passenger alarm in every vestibule (door area) on every train except on the Waterloo and City line (note that the Waterloo and City Line fleet is being overhauled to incorporate equipment required to comply with the Rail vehicle Accessibility Regulations 2010).
Passenger Emergency Alarms are fitted in wheelchair bays at heights determined to be operable by users between the 5th percentile female and 95th percentile males when using a reference wheelchair. These vary in height and design by fleet. Alarms available in other areas of the train also vary in height determined by the space available on the train but have been determined to be operable by standing users 5th percentile female and 95th percentile males.
We have assured our designs for accessibility and operation by the ‘smallest’ to ‘largest’ of our Customers (otherwise known as the 5th percentile female to 95th percentile male) including those who use wheelchairs. The PEAs are therefore positioned at a height to ensure that they can be accessed and operated by those standing and those using wheelchairs in the vestibule area.
London Overground:
For both 378s and 710s the PEAs are located on the right hand side of the double doorways as you exit through them. The 378s also have two extra buttons, one in each wheelchair section and the 710s have two Call for Aid buttons, also one in each wheelchair section.
On the 378s the buttons in each doorway are 1500mm from the train floor and 750mm in the wheelchair sections. For 710s, the passenger emergency alarms are 1460mm from the train floor and the call for aid buttons are 760mm in the wheelchair sections.
Docklands Light Railway:
Both the B2007s and B92s have a similar arrangement apart from the B92 Disabled Alarm Talkback unit (or DATU) height from floor level. The Passenger Alarm Talkback units or (PATUs) number 4 per vehicle and are located on the doors 1, 3, 6 and 8 at a height of approx. 164cm height from floor level. Disabled Alarm Talkback units (or DATUs), number 2 per vehicle, and are located in the area of the wheel chair spaces, at a height of approx. 73cm from floor level for the B2007 vehicle and approx. 86cm for the B92 vehicle. The illustrations attached (two halves of a complete vehicle) shows the positioning of the units highlighted in yellow.
Regarding question number 3 on Passenger Emergency Alarms (The number of times the emergency alarm was activated in 2023 due to mobility aid users being unable to deboard at their destination) this exact information is not recorded for the London Underground, the Elizabeth Line or the London Overground. For the DLR, there were a minimum of 25 activations due to passengers missing their stop (the remaining 189 activations are just recorded as general “passenger alarm activation”, with no reason recorded).
Regarding the questions on ramp and mini ramp usage, the information is not recorded for the London Underground. Nor is it recorded for the Elizabeth Line, although we do know that there were 12,413 prebooked passenger assists in 2023, but we are unable to determine how many of these required a ramp or mini-ramp (noting that not all passenger assistances require a ramp or mini ramp, as some stations have level boarding). For the London Overground, the total number of times a ramp was requested in 2023 was 23,747 times. The London Overground does not keep records of where a requested ramp or mini ramp was not available for a mobility aid user at their destination in 2023 (however, note that all London Overground stations that are wheelchair accessible are equipped with a ramp). The questions are not applicable to the DLR which did not have ramps or any mini ramps in use in 2023.
If this is not the information you are looking for please do not hesitate to contact me.
