Greater Anglia has told rail passengers to expect disruption to services in the coming weeks.
The latest wave of strike action and engineering works across the rail network are set to cause delays and cancellations between January 29 and February 6.
But how will services into and out of Norwich be impacted?
February 2: Strike
February 2 has been scheduled as a full strike day, meaning very few trains will be running across the country.
Jamie Burles, Greater Anglia's managing director, said "no services will run on most Greater Anglia routes" on this day.

However, he confirmed there will still be an "hourly service for limited hours" between Norwich and London Liverpool Street.
The first train will leave Norwich at 8am and the final train will leave London at 9.30pm.
January 29 - February 6: Action short of a strike
Apart from February 2, January 29 until February 6 will be days of "action short of a strike".
Mr Burles said that on the days not scheduled for a full strike, "the vast majority" of Greater Anglia services will run as normal but there will be "some alterations and cancellations" across the network.
Journey planners will be updated with exact train times three days before each strike date and passengers are urged to check before they travel.
February 3 - February 4: Engineering works
Engineering works will take place across the Greater Anglia network on the weekend of February 3 and February 4.
All lines will be closed between London Liverpool Street and Shenfield on February 4, meaning passengers from Norwich will have to take a connecting rail replacement bus from Shenfield into the capital.
Rail replacement services will also be available on other disrupted lines.
Passengers are advised to check journey planners before travelling on these dates.
