Londoners in their thousands have had journeys disrupted in the past month (November) and into December after Transport for London (TfL) announced the wheels needed urgently attending to.
Angry passengers left stranded at stations for half an hour before rail replacement services arrived shared their frustration on Wednesday (December 7) morning as delays continued .
Whilst many have been told by the Piccadilly line Twitter feed that they do not have a date for when repair works will end, getwestlondon put a few questions to London Underground about how long the mayhem will last.
When will the repair works come to an end?
A London Underground (LU) official said repairing one train takes two days.
"We don't have a timeline for it exactly, the problem with the wheels between 23 to 25 November knocked out two days to fix the train and we are repairing two trains a day," getwestlondon were told.
There are currently 56 trains on the line and in order to run a "good service", 70 are needed.
The spokesman said: "It is somewhere in the region of at least another week," although no guarantees can be made at this stage.
Could anything else impact how many delays are expected?
Although the London Undergournd is saying it could be "another week", commuters should not get their hopes up as there could be potential hurdles to set repair works back.
LU has said if there is any adverse weather, it could mean trains will have to be pulled once again due to damaged wheels.
As it currently stands, it said: "We have had conditions improve and they're not being damaged as much as they were - but it will depend on the weather."
Why was the whole fleet pulled from services at the same time?
London Underground said the wheels of trains were damaged by wet leaves which left them with no choice other than to pull half the fleet in order to repair them.
Whilst it caused chaos for those travelling in November , unions such as the RMT said the line should be closed until it's safe.
Can commuters claim for a refund due to delays?
If the tube was over 15 minutes late, passengers can claim a refund on the TfL website .
They will be backdated to November 24, but in an unfortunate piece of irony, TfL has said due to the large volumes of people, the money will take time to refund.
