I do not necessarily think that it would require electrification of the north Wales line. With respect, there are proposals at the moment to make improvements to the north Wales line that are based more around changes to signalling, which will allow more trains to run on the track. I do not pretend to be a rail engineer, but the proposals I have seen do not include electrification. They would decrease journey times across the north Wales line and, feeding into Crewe, would therefore decrease journey times between north Wales and London and bring benefits to all passengers.
