The first train service to make the journey from Norwich to London in 90 minutes has successfully arrived in the capital on time.
The train set off from Norwich station at 9am and called at Ipswich half an hour later.
It actually completed the journey two minutes ahead of schedule, arriving in London in 88 minutes instead of 90.
From now on, there will be four 'Norwich in 90' services a day on Mondays to Saturdays - with trains leaving Norwich at 9am and 5pm, and heading back in the opposite direction from London Liverpool Street at 11am and 7pm.
However, the trains will only stop at Ipswich and therefore will miss out other stations along the line including Diss, Colchester and Chelmsford.
The new services will shave 12 minutes off the current fastest journey between Norwich and London and will cut the fastest journey between Ipswich and London by four minutes.
MPs, councillors, and business leaders gathered at Norwich station on Monday morning for the launch of the new service.
The campaign for faster trains between Norwich and London has been ongoing for the best part of a decade and Greater Anglia managing director Jamie Burles told ITV News Anglia it's been a long time coming.
"We're just really proud today," he said.
"We've been working on this for quite some time, but today marks the start of the fastest ever scheduled train services from Norwich and Ipswich to London.
"These are additional services, so we're still running all of our existing services. We've done lots more than only stopping once.
"We've made sure that this train can accelerate and decelerate as fast as possible and we've made sure the speeds on the line to London have been smoothed out as much as possible so we can get there much quicker than normal."
