Bydd lefel y gwasanaeth yn cadw o leiaf at ei lefel bresennol. Bydd systemau awyru'n cael eu gosod ar yr holl stoc gerbydau wrth i'r fflyd gael ei thrawsnewid.
Power supplies will be available at over 95 per cent of seats across all rolling stock types by 2020, with 100 per cent roll out completed by 2022.

Air conditioning will be rolled out on all rolling-stock in the transformed fleet.
