Network Rail has apologised to passengers after it closed rail lines in areas where predicted heavy snow failed to materialise.
The company, which is responsible for maintaining tracks, announced on Monday that no trains would operate on Greater Anglia's rural routes on Tuesday and Wednesday, with a limited service on main lines.
It said it took this decision to enable operators to run "the safest and most effective service with the predicted conditions".
Although there was snow in parts of Norfolk, Suffolk and Essex, the anticipated heavy flurries fell further south in Kent.
Network Rail responded by lifting all restrictions on Greater Anglia routes but a full service is not expected to resume until Wednesday as the rail firm works to get drivers and trains in the correct locations.
