Currently Minor Delays on the Bakerloo Line due to 'a faulty track at Waterloo'. What is meant by this more specifically?

There may be slower journey times or less trains in consequence. The "faulty track", could be a few things, something noticed during traffic hours by train operators and the ESR being put in, or during engineering hours patrols, for attention at a later point or data from the Track Recorder. |

It can also mean a track circuit failure, but in this case I believe it was a faulty rail.

A track circuit failure would be a signal failure in punter-facing language... but it is an element of the signalling system so is true.

Confusingly, I have heard NR track circuits referred to as "tracks", thus a "track" failure would be a failed track circuit. Calling it a "track failure" when addressing Joe Public would be confusing, but they do it anyway.

In fact, the term track circuit is surprisingly rarely heard. |

In fact, the term track circuit is surprisingly rarely heard. LUL use "track" all the time, the three basic failures of the signalling systems are "track", "point" and "signal". The one most often heard by the public will be "signal" because any of the basic three failures will result in a signal failure. Until the Technical Officer arrives to localise the failure the detailed cause is often unknown. All sorts of things electrical, mechanical and other can cause the basic failures i.e. faulty relays, trainstops, motors, valves, blown fuses, faulty cables and broken trackwires, shorted blockjoints, earthing faults, traction issues, loss of mechanical adjustment, rodents, insects, hedgehogs etc. Thus even a basic failure may be described in different ways but generally the public will never hear more than the basic three types. |
