The AM has previously called for a metro hub at the Celtic Manor, along with suggestions of a regular bus connection to Monmouth, allowing residents quick and easy access to more parts of Wales.
Mr Ramsay told the Beacon: "Now that rail is being devolved, I’m calling on the Welsh Government to look at undertaking feasibility studies into light rail/tram solutions to cement Monmouth’s position on the metro map.
"New light or heavy rail services clearly provide a more durable solution over the longer term.
"Given some of the calls in West Wales for the Carmarthenshire-Aberystwyth railway line to be reopened, the Welsh Government should look at whether there is any future scope for reinstating closed routes or developing new rail or tram services - which can utilise roads too - in Monmouthshire. The problem with heavy rail solutions is they are extremely expensive, particularly once the former infrastructure has been lost."
Mr Ramsay said that he believes the devolution of rail to the Assembly is a positive move that will give the Welsh Government greater flexibility in developing rail services which are suited to the future transport needs of Wales.
He said: "There is of course the issue of cross border services but this has been taken into account during the discussions between the UK and Welsh Governments.
In 2015 the Beacon reported that while plans to bring Chepstow into the Metro network were under way, Monmouth was dropped as one of the locations, with Mr Ramsay expressing deep concern at the time that the town was no longer part of the proposed South East Wales Metro network. The map published by the Welsh Government showed the Metro extending along existing rail links to Abergavenny and Chepstow but previously outlined Metro links to the county town itself have seemingly vanished.
