Mr. Hugh Creegan:

The short answer is that if there were more fleet coming in, it would allow greater deployment of trains and, therefore, increased capacity. Against that, we have to balance that we are undertaking the DART+ programme, which is extending electrification and replacing diesel fleet with electrified fleet. We will see the diesel fleet cascading onto other lines. We have to be careful that we do not undermine this fleet deployment strategy by over-purchasing diesel fleet and finding later on that we have more than we need and we are unable to put in the electrified services that we want to in certain places.
