TfL have published their response to issues raised by local people about the proposed extension. Below is an extract of the report relating to Beckenham. The full report can be found at:
8.1 Beckenham Junction and Hayes already have sufficient public transport links & 8.2 The proposed route duplicates the current Hayes branch
The option of extending a Bakerloo line onto the current Hayes branch has been proposed for three key reasons:
- The trains that currently operate on these lines could be reallocated elsewhere to provide greater capacity on other rail lines.
- Converting the Hayes branch to London Underground is expected to increase the frequency of services and most journey times could reduce. For more information see Appendix C – Proposed Bakerloo line extension (to Hayes and Beckenham Junction) frequency in comparison to current rail services and Appendix D – Estimated journey times with a proposed Bakerloo line extension.
- Converting the Hayes branch to London Underground and utilising the existing infrastructure is currently expected to cost less than installing new infrastructure for the proposed extension beyond Lewisham.
The conversion of the Hayes branch to London Underground was also suggested by Network Rail in the Kent Route Utilisation Strategy (2010) for the rail network from London into Kent.
As part its long term planning process, Network Rail is commencing a Route Study for the Kent region in 2015. This study, which is anticipated to be completed in 2016, includes consideration of the Hayes line branch TfL will work with Network Rail and other industry partners during this study to understand the options that exist for improving capacity More information about Network Rail’s planning work is available online at: https://www.networkrail.co.uk/long-term-planning-process/
8.3 Extending beyond Lewisham is cost prohibitive
Extending the Bakerloo line beyond Lewisham to Hayes and Beckenham Junction could be achieved by converting the existing National Rail branch to London Underground. Without this existing infrastructure, a longer extension would have a higher total cost.
8.4 Tube access is not required as far as Beckenham Junction and Hayes
The Central, Piccadilly, Northern, District and Metropolitan lines all have stations at a similar distance, or further away, from central London than the Hayes station.
An Underground extension could improve the frequency of services to locations along the route of the proposed extension, as shown in Appendix C – Proposed Bakerloo line extension (to Hayes and Beckenham Junction) frequency in comparison to current rail services and in Appendix D – Estimated journey times with a proposed Bakerloo line extension.
8.5 Extending the line to Beckenham Junction and Hayes could lead to overcrowding on the Bakerloo line
The Bakerloo line offers an opportunity for an extension as it has spare capacity and this is forecast to continue following the planned line upgrade.
For more information see Appendix E – Future crowding forecast for Underground and DLR, 2031. In addition, the Bakerloo line is planned to operate up to 27 trains per hour (tph) following its upgrade. Modern systems provided by this upgrade might have the capability to enable service levels above 27 tph – the Victoria and Jubilee lines both achieve train service frequencies of over 32 tph. As option development work continues, demand modelling will be reviewed and updated.
8.6 Preference to extend the Bakerloo line to Beckenham Junction or Hayes (one or the other, but not both)
Extending the line to either Beckenham Junction or Hayes would require the proposed extension taking over the Hayes National Rail branch south of Lewisham. As National Rail services that currently serve these destinations would be reallocated, if the proposed underground extension terminated at Beckenham Junction and did not serve the terminus at Hayes, stations south of New Beckenham would lose a rail service.
Currently, there are no timetabled services on the Hayes to Lewisham National Rail branch to or from Beckenham Junction. If the proposed extension only served the Hayes Page 24 of 40 terminus and not Beckenham Junction, there would not be a loss in rail services for existing passengers. However, a proposed extension also serving Beckenham Junction could provide an interchange opportunity with Tramlink and other rail services towards Kent, Dulwich and Brixton.
8.7 Concern that the proposed extended Bakerloo line would not have the same capacity and provision that current National Rail train services provide, i.e. passenger capacity and bicycle carriage.
Although London Underground trains are smaller than National Rail trains, they operate at a high frequency, and therefore can provide high overall capacity.
The extension option to Hayes was based upon an estimated service of 27 trains per hour (tph) between Elephant & Castle and Catford Bridge, 21 tph between Catford Bridge and New Beckenham, six tph between New Beckenham and Beckenham Junction and 15 tph between New Beckenham and Hayes.
The table below shows how the capacity of London Underground Bakerloo line train services compares to existing National Rail services to Hayes. Currently the Hayes National Rail branch receives two Cannon Street services consisting of 12-car Class 376 Electrostar trains and four Charing Cross services consisting of 10-car length Class 465 or 466 train types. The 465 train has been used in the table below as it has the higher total capacity.
The table shows that on the Hayes branch there would be a slight reduction in seated capacity between Hayes and New Beckenham but an increase in total capacity.
Beckenham Junction would benefit from new regular train services of at least six tph. From New Beckenham to Lewisham, there would be an increase in seating capacity and an increase in standing capacity for users of the line compared to the existing services that operate. If the 10-car trains that currently operate were lengthened to 12-car, seated capacity would still be lower than the proposed Bakerloo line service.
Note: the table below assumes the current forecast capacity of a Bakerloo line train following a planned upgrade to trains. The train timetabling estimates are also subject to further development.
Foldable bikes are permitted on the entire Underground network at any time of the day. Non-folded bikes are currently permitted on above-ground sections of the Underground network outside the peak times of 0730 to 0930 and 1600 to 1900 hours. Based upon this current policy, non-folded bicycles would be permitted between Ladywell and Hayes outside of these peak times as this extension option is expected to run at surface.
8.8 What will the train timetable be for services to and from Beckenham Junction and Hayes
Planning for the extension has assumed an estimated service pattern of 15 trains per hour (tph) to Hayes and six tph to Beckenham Junction. A further six tph is assumed to reverse at Catford Bridge, making 27 tph on the extension north of Catford Bridge into central London.
Trains would be scheduled to service termini and intermediate stations in a regular service pattern to manage demand and provide predictable departures. The service assumptions for any proposed Bakerloo line extenison option would be developed in more detail as part of future work.
8.9 Suggestion to tunnel all the way to Beckenham Junction and Bromley, rather than taking over the Hayes branch
Constructing an extension in a tunnel would be more expensive than converting the existing rail corridor. For this reason, it is likely that a tunnelled extension beyond Lewisham would represent lower value for money.
Further, a tunnelled extension would not provide the potential capacity benefits elsewhere on the rail network. One of the key drivers of the proposed extension is converting the Hayes line so the current National Rail services on this line can be reallocated.
8.10 Concerns regarding disruption that may be caused to services during construction
Subject to construction methodology, it would be TfL’s aspiration to maintain a rail service on the Hayes National Rail branch during construction.
8.11 Oppose a Tube extension serving Hayes and Beckenham Junction as this would lead to too much new development
An extension to Hayes and Beckenham Junction has been proposed because it can improve the rail services on the line by increasing their frequency and capacity.
Further, by converting the line to London Underground, trains that currently operate on these lines could be reallocated elsewhere to provide greater capacity on other rail lines, helping to support future growth in southeast London.

I too sent a letter to Vicki Foxcroft raising concerns about this extension as I live in Ladywell whose station is grade two listed and we don’t want this tampered with or disruption all night tubes would bring among many other reasons which you have clearly stated . The reason why I write now is that a worker at Ladywell Station said his manager (who is based at Eden Park Station) had told him that the Hayes line will stop calling at Charing Cross from May 19 and will call at Cannon Street and possibly Victoria. I can’t find any written proposal within their timetable plans for May 19 or anywhere else so not sure how to combat it or who to direct concerns. Worry that they will slip this in by stealth as they did to Greenwich. Have you heard any thing ?
