Where did KeolisAmey plan to maintain the class 170s once the 231s took over the Maesteg, Ebbw Vale and Cheltenham Spa workings? Obviously there are now the active travel 153s taking over some of the planned 170 work, but equally there is more planned work for 197s in the south (though perhaps not Cardiff) than the original plan in that regard.Bear in mind that in the long term there should be a much fewer 197s working around Cardiff when the 231s go on the routes they're meant to be on.
