One faulty track leaves Harlesden and two other stations with no trains
The Bakerloo and Lioness lines share a ten-station stretch through Harlesden, and their closures overlap at six of them.

A single faulty track at Harlesden has left three north-west London stations without any train service, because the only two lines that serve them are both shut through it, TfL's records showed on Friday 14 August 2026.
The Bakerloo entry reads: "Bakerloo Line: No service between Queen's Park and Harrow & Wealdstone and MINOR DELAYS on the rest of the line while we fix a faulty track at Harlesden. Tickets are being accepted on London Northwestern Railway and London Buses."
The Lioness entry names the same fault: "No service between Watford Junction and Willesden Junction while we fix a faulty track at Harlesden. MINOR DELAYS on the rest of the line. Tickets are being accepted on London Underground."
The two lines run the same stations for a long stretch. TfL's route data lists both calling, in the same order, at Queen's Park, Kensal Green, Willesden Junction, Harlesden, Stonebridge Park, Wembley Central, North Wembley, South Kenton, Kenton and Harrow & Wealdstone.
Six of those ten sit inside both closed sections: Harlesden, Stonebridge Park, Wembley Central, North Wembley, South Kenton and Kenton. At those stations, neither line is running.
Three of the six have nothing else. TfL's station records for Harlesden, Stonebridge Park and North Wembley each list the Bakerloo and the Lioness, and no other rail line. The Smoke did not check the records for Wembley Central, South Kenton or Kenton.
What TfL offers instead differs by line. Bakerloo tickets are accepted on London Northwestern Railway and London Buses. The Lioness entry directs passengers to London Underground, and at those three stations the only Underground line is the Bakerloo, which has no service there.
The Smoke reported earlier today that the Harlesden fault had closed sections of both lines, with track faults then standing at five locations across six lines.
TfL publishes no passenger count for the three stations on the pages consulted, so the record gives no figure for how many people the closure leaves without a train.
Neither entry carries an estimate of when the track will be fixed, and neither names a replacement bus for the stretch the two lines share.
Still unanswered
The documents this story was reported from do not answer these questions.
- When TfL expects to fix the faulty track at Harlesden and reopen the two lines; neither entry gives a time.
- Whether any replacement bus is running along the closed stretch the Bakerloo and Lioness share; neither entry names one.
