You know, I think Mr C may have a good idea about being held outside Cardiff waiting for platforms as, if I’m not mistaken, is viewing it from the front window of the 67 or DVT.
I must also add that you say you feel it important to raise the issues you see when you travel, but that’s rather different from virtually insisting that the change that would suit you best, is the best overall option.
I have a feeling TFW would have looked at the numbers, figured where their bread was buttered and hence the reason they made the changes that they made. If they thought the money was in cross Cardiff connections, they’d have made changes to try and make the most money from that instead.
