Today's issues to the lines are described as such by TfL on their website:
- Elizabeth Line: No service between Heathrow T2&3 and Heathrow T5 due to a faulty train at T5. GOOD SERVICE on the rest of the line.
- Piccadilly Line:
- No service between Rayners Lane and Uxbridge due to difficult track conditions caused by significant leaf fall. (not really related to LHR, but it's something that has consistently cracked me up over the years, I wonder how they manage in autumn in the taiga section of the Transsiberian!)
- No service between Rayners Lane and Uxbridge due to difficult track conditions caused by significant leaf fall.
