Clearing them elswhere on the valleys is a big challenge. Lots of works required. They might look like a 150 but they’ve got yaw dampers and are significantly heavier. Even Cardiff Bay is challenging!The bodyshells are very similar to class 150s so clearing them for the other routes could be quite easy. I think it was only ever planned for seven of the nine units to be diagrammed. That could be achieved if they can run the Cardiff Bay to Caerphilly shuttle.
