Hi,
I regret having to make this request but given the reluctance for TfL to make this information available easily, I am forced to go by this route.
I would like to know the following information for so far this calendar year. So, for clarity, that is all months from January to June 2023 inclusive. If possible, I would prefer it split into individual months.
For all Elizabeth Line services, how many Elizabeth Line train faults have occurred that have led to a delay of an Elizabeth Line service?
For further clarity:
Only include Elizabeth Line trains.
A fault includes any mechanical, electrical or software fault.
A train that has developed a fault which has been remedied and then develops either another fault (or a recurrence of the previous fault) is to be counted as 2 faults.
It doesn't matter whether the fault only affects the one service or multiple services, it only counts as a single fault.
If it makes it quicker for you, I am happy to simply receive raw data, that would allow me to extract the requested information electronically myself.
