The Office of Rail Regulation (ORR) said on Wednesday it had launched an urgent investigation.
'Critical issue'
Chairman of the ORR, Chris Bolt, said: "We fined Network Rail for its project planning and management failings after it failed to complete the Portsmouth re-signalling project last Christmas.
"It is extremely disappointing to have a repeat of that experience on key parts of the network."

Network Rail apologised to passengers for the disruption caused by the "unacceptable" overrun.
It said the West Coast route through the Rugby area would remain closed for "at least the remainder" of Wednesday but it could be well into Thursday before services resume.
A spokesman said the "critical issue" was a shortage of specialist engineering staff, but additional manpower had been drafted in and was working "flat out" to restore the services as quickly as possible.
Network Rail said mainline services on the Great Eastern routes through to Norwich, which have been affected by the Liverpool Street works, would be restored on Wednesday afternoon.
Suburban services would continue to terminate at Stratford in east London, with a full service expected to run from Thursday morning.
Fare rises
Operations and customer services director Robin Gisby said: "Both these overruns are completely unacceptable and an urgent investigation into what has gone wrong has been launched.
"We are deeply sorry for the further disruption this news will cause to passengers.
"We are very grateful for the support of the train operating companies and London Underground in helping us deal with these unacceptable delays."

Tony Ambrose is the founder of More Train Less Strain - a group which is planning a fare strike in protest at increases brought in by First Great Western.
He told BBC Radio Five Live: "The company itself put a letter on every passenger's seat a week before Christmas saying that they realised they were running a very poor train service and they knew they had to do better.
"But what they didn't tell us is that two weeks later they were going to put the fares up by 10%.
"What other commercial company would put prices up at a time when they tell you they are running a rubbish service?"
