Id say that having a service to/from both Newport and Cardiff per hour is a nice balance. Id imagine people would want to travel to both cities, Newport as its closer to Ebbw Vale plus Cardiff being the capital has a lot more to offer in terms of work and social life.
Going back on topic, does anyone know what date we can expect the first 3 car 197 into service? Given so many services are transferring from May onwards its going to be a decrease in capacity for some routes if its 2 cars initially.
