TfL has confirmed that the December 16th launch of Night Tube services on the Piccadilly line will go ahead as planned, despite trains being a bit buggered at the moment.
The combination of bad weather, an unprecedented number of wet leaves on track and old, old rolling stock has led to wheel damage, causing a significant shortage of working trains. Around two have been returning to action each day, with TfL saying that 66 out of 86 are now back in business.
While that’s not enough trains to adequately serve daytime commuters, it turns out that the 24-hour Piccadilly line service will only require around 25 trains, running every 10 minutes between Cockfosters and Heathrow Terminal 5.
We’re not yet sure when the Piccadilly line will fully recover, but the RMT union -- which has called for the Night Tube launch to be pushed back -- says the problems could continue into February. [Londonist]
