Mae Llywodraeth Cymru yn gwneud cais hefyd am £40 miliwn arall o leiaf o gyllid yr UE i gefnogi gwelliannau i seilwaith y Metro a fydd gobeithio wedi'i sicrhau erbyn diwedd 2018.
The Welsh Government is also applying for a further £40million plus in EU funding to support Metro infrastructure enhancements, which it hopes will be secured by the end of 2018.
