The horrors of Halloween came early for hardworking Londoners traveling on the Central Line on Wednesday.
The second-most frequent line on the London Underground ground to a halt in morning peak as heavy rain wreaked havoc with its signals.
The line normally runs around 34 trains per hour through central London but restrictions placed upon services meant this number was severely reduced.
Thousands were left waiting for those trains still running on the line as alternative routes also encountered problems. Delays were reported on Transport for London's website across the Circle, District and Hammersmith and City lines.
Heavy rain which fell overnight and through the morning is thought to have added to the problems, with commuters facing a soggy, snail's pace journey.
Londoners were understandably rather pissed off

It's taken me 45 minutes to get from Bond Street to St. Paul's. That is 4 stops. Let's comprehend the state of the Central Line right now.— Sadiq Ali Jaffer (@SadiqAliJaffer) October 28, 2015
