I would love to see DTG do a Irish or northern Irish railway route as it will be a bigger expansion for what’s already been created I hope they choose a Irish or Northern Ireland network Belfast to Derry or any of the other routes in the network.
Add more details and The exception being Belfast Newry Dublin Railway Line. One reason is that Newry is the United Kingdom Ireland Border Station any trains South of there need CAWS Ireland. Safety systems are basically the same as British route after Tees Valley Line 1989 AWS TPWS DSD.
