The tram part for which they have been partly ordered is the first stage of the Cardiff Metro route which will run between Cardiff Bay and Cardiff Central on an as yet to be constructed street tramway. Last updates on that were that it would be 2028 that would be ready for use \u2013 but as work hasn\u2019t really commenced on that whether that is achievable remains to be seen.<\/p>\n The units which are being used are mainly being allocated to service on the Cardiff Bay-Pontypridd route (which includes some shorter shuttles).<\/p>\n 398 018 was one of three class 398s in service on a short visit to Taff\u2019s Well and is seen here with one of the class 756 tri-mode units also part of the major investment in rolling stock by Transport for Wales.<\/p><\/div>\n![\"\"](\"http:\/\/www.britishtramsonline.co.uk\/news\/wp-content\/uploads\/2026\/09\/1.018-dc.jpg\")
