Havering (East London Times) August 3, 2026 – Transport for London (TfL) has confirmed that plans remain firmly “on track” to launch the new SL12 Superloop express bus route across Havering and outer East London later in 2026.
As initially reported by the Romford Recorder, the transport authority affirmed its commitment to expanding outer London’s express transit infrastructure following questions regarding the service’s progress. Speaking to the publication, a spokesperson for Transport for London stated: “TfL is still on track to launch SL12 later this year. Launch date will be announced in due course.” While the spokesperson declined to provide a specific date for the official ribbon-cutting, the update reassures local commuters that the long-anticipated cross-borough service is nearing operational reality.
The announcement follows an extensive public consultation process conducted by TfL, which initially unveiled proposals in spring last year to expand the outer-London express bus network. The SL12 route is designed to plug historical transport gaps in East London by connecting major commercial, healthcare, and residential centers. The service will serve multiple major interchanges across Havering and neighbouring boroughs, stretching from Gants Hill down to the industrial zone at Rainham’s Ferry Lane. Key stops along the corridor include Romford, Elm Park, and Queen’s Hospital, providing orbital connections that bypass central London bottlenecks.
Public engagement regarding the proposed transit corridor yielded overwhelmingly positive feedback. Transport for London confirmed that a total of 805 people submitted formal responses during the public consultation. Of those who answered the specific survey question, 79 per cent stated that the introduction of an express route would make their everyday journeys significantly more convenient. Furthermore, as highlighted in official TfL consultation findings covered by local outlets, 69 per cent of respondents noted they would be more likely to choose public bus transport over private car travel once the SL12 becomes operational.
In response to direct feedback gathered during the public engagement phase, TfL made specific structural operational adjustments to the finalized route layout. As published in TfL’s consultation report and reported by transport press, the authority agreed to alter the path in Rainham so that the service calls at the Rainham Tesco bus stop (stop F) in both directions. This change aims to deliver a consistent link for local shoppers and nearby residents. Additionally, in Romford town centre, TfL shifted the designated pick-up and drop-off points from the originally proposed stops V and T to bus stops Y and Z near Romford station. Transport planners believe these modified stop allocations will enhance passenger interchange efficiency, giving travelers a wider selection of immediate onward connections to the Elizabeth line, London Overground, and local bus networks.
Operational specifications confirmed by TfL indicate that the SL12 will run daily with robust service frequencies. Between Monday and Saturday during daytime hours, buses will run every 12 minutes. During evenings, early mornings, and all day on Sundays, the frequency will shift to every 15 minutes. Standard TfL fares and concessions—including the Hopper fare and Freedom Passes—will apply fully across the entire express route.
When Was the Superloop Expansion First Proposed for Havering?
The journey toward bringing an express Superloop corridor to Havering began when Transport for London first introduced the broader Superloop concept—a 138-kilometre network of orbital, limited-stop bus services surrounding outer London. Following the launch of initial routes in 2023, Mayor Sadiq Khan and TfL announced plans to extend the network into previously unserved outer boroughs.
Official public consultations for the SL12 route specifically were opened between March 28, 2025, and May 23, 2025. During this period, transport planners sought public opinion on establishing an express link connecting Rainham, Ferry Lane, and Gants Hill via Romford. As noted by Geoff Hobbs, TfL’s Director of Public Transport Service Planning, during the launch of the scheme’s feedback window, outer London demonstrated a clear demand for express orbital transport to better connect local communities without requiring travel into central London zones.
Local authority leadership strongly backed the initial proposal. Writing in response to the outcome of TfL’s consultation report, Councillor Ray Morgon, Leader of Havering Council, welcomed the outcome, describing the route as a “vital connection for Havering” and noting it represented a major milestone in the council’s ongoing campaign to secure stronger north-south transit infrastructure across the borough.
Background of the Particular Development
The development of the SL12 Superloop route sits within a broader effort by Transport for London and the Mayor of London to modernize transit infrastructure in outer London boroughs. Historically, outer London transport networks have been heavily radial, prioritizing travel into and out of Central London while offering limited, slower options for orbital travel between neighboring towns and local commercial centres.
When TfL launched the initial Superloop network in June 2023, early operational data demonstrated a marked increase in passenger usage. TfL figures showed that average passenger numbers along Superloop corridors grew by 5 per cent—outperforming the broader network growth average by 12 per cent. Despite this success, early iterations of the Superloop map drew criticism from local politicians and residents in Havering, who noted that the borough had been completely omitted from the original circuit.
In response, local campaigning by Havering Council, community action groups, and regional stakeholders pressed TfL to address orbital deficiencies in East London. The resulting SL12 route was engineered specifically to connect isolated residential areas, major NHS healthcare facilities (such as Queen’s Hospital in Romford and King George Hospital in Goodmayes), and rapidly expanding commercial hubs like the Ferry Lane Industrial Estate in Rainham, which previously lacked direct public bus connections.
Predictions: How Will the SL12 Route Affect Passengers and Local Commuters?
The launch of the SL12 Superloop service in 2026 is projected to deliver several direct, measurable impacts for residents, workers, and businesses across Havering, Redbridge, and Barking & Dagenham:
- Reduced Travel Times for Hospital Visitors and Staff: By offering limited-stop express transit between major hubs, health workers, patients, and visitors will experience significantly shorter travel times between Queen’s Hospital in Romford, King George Hospital, and surrounding residential communities.
- Enhanced Industrial and Employment Access: Commuters working at Rainham’s Ferry Lane Industrial Estate will gain direct, high-frequency public transport access for the first time, helping local businesses recruit talent while offering workers a cost-effective commute.
- Modal Shift Away from Private Car Usage: With nearly 70 per cent of consultation respondents indicating a higher likelihood of choosing the bus over personal driving once SL12 launches, the express service is likely to alleviate local traffic congestion along key arterial roadways such as the A12 and Eastern Avenue corridors.
- Improved Multi-Modal Interchange: Passengers connecting to major rail networks—including the Elizabeth line at Romford, the Central line at Gants Hill, and the District line at Elm Park—will see smoother transfers, unlocking wider geographic travel across Greater London without additional travel stress.
