T he number of disruptions are based on delays to the train service of 2 minutes or more where a train in passenger service has either been
delayed or withdrawn due to an issue related to the train. Whilst an issue may have caused a delay to the service, in many cases the train wil
have continued in service for the rest of the day without any subsequent delays, or the need to withdraw it.

It is believed the record for acceleration is held by an S 8, whilst not in passenger service. T he simple answer is they al accelerate at the same
rate, with the exception of the B akerloo and P iccadilly, which do lack horsepower. It is the signalling system that restricts the maximum allowed
acceleration, not the train itself.
