A fault that may require repair work is the source of this morning's peak hour delays in Bromley.

National Rail was advised at about 5.30am this morning that due to a track circuit failure in the Crofton Park area, trains from Southeastern and Thameslink could be delays until at least midday.

"On approach to Crofton Park train crews will contact the signalling centre to confirm their location, whereby the signaller will then manually authorise each train past the affected signal which is consequently held at red," a message read on the National Rail website.

"Discussions are still in place between the train operators and Network Rail as to when the fault will be rectified; however, there is a possibility of engineers attending after the morning peak to effect necessary repairs.

"Sometimes Network Rail has to carry out engineering work at short notice, and we can't give you much warning. We'll still let you know as far in advance as we can."

The fault between Denmark Hill and Bromley South means that trains running between those two stations may be delayed or revised

All trains passing through Crofton Park towards Orpington and Sevenoaks will be delayed between 5-10 minutes. Specifically, these services are:

  • London Blackfriars to Sevenoaks
  • Luton to Orpington
  • West Hampstead to Orpington

Southeastern trains that run from Victoria towards Rochester/Gillingham/Dover will be diverted, not calling at Denmark Hill and some other trains may be delayed. Trains towards London Victoria will call there as normal.

Thameslink travellers have been advised by National Rail to "continue your journey as usual this morning as a regular service will still run."

"If you're making an essential trip, you may wish to check for individual service updates on this line.

"You can do this via the online journey planner, or by speaking to station staff."
