National Express East Coast has shown the highest improvement among all the rail operators in Britain, according to a new survey.
Results of a survey conducted by the Office of Rail Regulation showed that nearly 90.4% of the rail operator's trains arrived on time in the first three months of 2009, an increase of 4.3% over the same period in 2008.
The jump is the biggest for any British train operator, according to the quarterly National Rail Trends survey.
National Express East Coast is nationalised, after its former parent company National Express was forced to give it up following a $1.7bn debt. National Express is up for takeover.
In the same survey, c2c, which operates trains between London and the Essex coast, was named as Britain's most punctual train operator with a 96.7% punctuality rate.
