Southern & SWT are now moving again, with some trains delayed and/or having been run at caution, but London Overground remain disrupted. The trespasser has been wandering around unpredictably in an awkward area which has encompassed the BML, SWML and the Ludgate Lines, effectively stopping the job for each, one at a time, and resulting in GSM-R calls which have also spilled over to the rest of the surroundings. However staff are now trying to actually detain the trespasser after they have been found again.
