The Office of Rail Regulation (ORR) has launched a consultation into its 2008/09 business plan.
The consultation will help set health and safety and economic regulation for the period between April 2008 and March 2009.
ORR Chief Executive Bill Emery said, "During the first two years of our present corporate strategy, the railway has continued to develop in positive ways.
"Safety, performance and efficiency have improved, and we are moving closer to our decisions on access charges and Network Rail's outputs for the five years from April 2009. Also we have continued to improve our own efficiency and effectiveness as the integrated regulator of Britain's railways.
"Now we are asking interested parties to tell us the priorities we should be adopting to ensure that improvement in railway services to passengers and freight customers continue throughout 2008-09," he said.
2008 will complete the ORR's work on the five-yearly periodic review of access charges and the outcomes required from Network Rail. The economic and safety regulator will also continue to assess industry performance and, where necessary, enforce compliance with health and safety law and licence obligations.
Responses to the consultation are sought by Friday 25 January 2008, and ORR expects to publish its business plan in March 2008.
