East Coast has become the first train company to announce fares for 2014, revealing a freeze on more than half its to-and-from London fares and below-inflation rises on others.
But its regulated fares, which include season tickets, are rising by the recently-agreed 3.1% average which is in line with the July 2013 RPI inflation rate on which the January 2014 national rises are based.
East Coast, which has been run in the public sector for the last four years, operates services from London up the east side of England to Scotland.
The company has said its overall average rise for all fares from January 2 2014 was 1.21% with unregulated fares which include off-peak and advanced-purchased tickets going up by an average of 0.83%.
