Before, that though GWR need to look at where you have the most passengers get on/off the Cardiff - Portsmouth trains and as discussed on other threads, maybe have it such that more local passengers are not using the GWR Semi - Express service, but are actually using more of the local services, even if they are stopping at more stations. For instance, if you have a customer travelling from Cardiff Central to Newport (South Wales), then you have the GWR service as pickup only from Newport (South Wales) station. So for instance anyone travelling to Newport (South Wales) could for example go on a TFW service to Gloucester. It stops at the same amount of stops as the GWR service to Severn Tunnel Junction, so the time travelled would not be any different to using the GWR service.
