A shuttle service operates, known by the staff as "the popper". The service is three trains per hour in each direction. Public holidays and Sundays are not operated by the franchisee. Through services were originally operated from Bromley North to Holborn Viaduct, Victoria, Cannon Street and Charing Cross. These were cut to a peak-hours only service in 1976, and were then withdrawn completely in 1990.
Additional use during engineering works
Bromley North Station also serves as an alternative station for Bromley, when engineering works are being carried out on the Chatham Main Line or when other maintenance works are occurring at Bromley South. Trains are diverted from London Victoria to Bromley North via Lewisham and Grove Park, and vice versa. During this operation, it is more common to see Class 375s and 376s as well as Southeastern Networkers.
Trains
rolling stock primarily operates on this route, replacing class 466 stock in late 2019 due to the prohibition on units lacking accessible toilets to run alone. Until 2010 this was the only 'true branch', that is branch-only service, in Greater London for trains to be worked with a driver and a guard. Since 2010 this is now driver-only, as mirrors and monitors have been provided on the platforms to allow the driver to look back.
Future proposals
The Southeastern Main Line into central London is at full capacity. Service patterns have begun to entrench all longer distance service destinations as direct, many trains per hour, stations. Therefore, Southeastern consider that it is not economically justifiable to reinstate direct services from Bromley North into central London, and consequently all services must terminate at Grove Park for the foreseeable future. Various proposals have been put forward to convert the Bromley North Line to an alternative mode of transport to make better use of this isolated piece of rail infrastructure. Transport for London have indicated that they are considering a number of possible options for connecting the Bromley North Line to one of the other public transport systems in London, including:
conversion for tram use as an extension of the Tramlink system
incorporation into the London Overground via — problems of line capacity make this a less likely solution.
These schemes have not been taken beyond the proposal stage and recommendations are expected to be published around 2017. In a report published by the London Borough of Bromley in 2012, proposals to extend Tramlink beyond Beckenham Junction into Bromley town centre are outlined, with a further option to continue this route along the Bromley North Line to Grove Park. The report also considers the Bakerloo line extension favourably, but notes difficulties with tunnelling between Lewisham and Grove Park, and with the provision of a depot. The Tramlink proposal also features in the Rail Utilisation Strategy report by Network Rail.
