More capacity is needed on local railways to serve rising passenger numbers, says a transport campaigner.

Aire Valley Rail Users' Group chairman Tim Calow also called for changes in attitude by rail bosses.

He suggested solutions such as more, longer or faster trains on the line through Keighley.

Mr Calow was writing an overview of local rail travel in the 50th issue of the group's magazine Airelines.

He looked at progress over the past 20 years, current problems and potential solutions over the next two decades.

He said many trains which left Skipton on time, travelling through Keighley, were late by the time they reached Shipley.

Mr Calow believed passenger numbers would continue to rise, especially on the route into Leeds.

He said: "Building more roads is not realistic or sustainable so we will need more capacity on the railway."

Mr Calow said more trains would need improvements to the signals and longer trains would need major rebuilding of stations.

The rail users' group holds its annual meeting on April 19, at 2pm, in Saltaire Methodist Church Hall.
