Since the 1990s, the line which has two stations of its own has been served almost exclusively by shuttle services to and from Grove Park railway station in the London Borough of Lewisham, where passengers can change trains for onward journeys towards Central London, as well as towards Kent.

[citation needed] 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.

In the 1980s, a plan to partially convert the line into a heritage railway using retired London Underground rolling stock was considered, but did not ultimately come to fruition.

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.
