According to Southeastern a “disturbance on a train” this afternoon is causing many delays out of London Bridge this evening.
Not a great night for it with the Jubilee Line suffering the effects of shortage of trains due to cracks being discovered on one train last night – as covered here.
⚠️ Severe delays to the entire line.
ℹ️ This is due to mechanical issues we have identified on a number of our trains.

Maybe try the Thames Clipper if you can – though that may also be a tad busy as a new stop at Royal Wharf serving 5,000 people finally opened this week.
Or go to the pub.
