I know this is a dead horse that's been flogged way too many times on these forums, but I truly believe it's the only way cwl is going to draw any significant West country traffic from LHR.A lot of the feedback I see about the route is about the convenience it brings in bringing people close to home and negating a journey back from lhr. I wonder if for the West country that convenience is lessened?
Considering the Welsh Gov is spending ~100m on the link road through Pendoylan to improve connectivity for the airport to the M4, I'm even more surprised Transport for Wales (TFW) didn't include a roughly £20-30m spur to the airport from the Vale of Glamorgan line in the metro plans.
This, on top of a relatively modest subsidy to the train operating companies, would improve the access to CWL from the wealthier markets in the West Country so much more effectively.
If the Welsh Gov could then negotiate with GWR to extend their Portsmouth Harbour to Cardiff and Taunton to Cardiff services, there would be a half hourly service through Bristol, Filton Abbey Wood and Newport directly to the airport. That would be on top of connecting Bath, Bradford-upon-Avon, Salisbury, Southampton, Western-Super-Mare and more than 20 other stations in the SW with an hourly service to the airport. The Taunton train in particular stops at most of the outer lying Bristol suburbs such as Yatton, Worle and Bedminster.
The one place such a route and subsidy won't stand up for now, is on the value for money for the tax payer. With the Legal and General industrial park planned for next to the airport, the arithmetic may change on that rather rapidly.
But it's definitely a significant way the Welsh Gov could add value to CWL without breaking state aid rules or burdening the airport with more loans.
Just think, not just about connectivity to the airport either, but the advertisement for the airport. Every half hour, at Bristol Temple Meads and at so many others, there would be tannoy announcements, information screens and millions of journeys a year from places like Romsey to Salisbury, all on the Cardiff Airport train. The reinforcement of the ease of access and, in a lot of cases, the airport's existence would be priceless.
The fact is, Cardiff is never going to have 'those orange planes' nor is it going to have the destinations of LHR. As it stands, access to CWL is an afterthought once a decision is made to fly to or from there.
Having the only regular, direct train service from such an affluent area to an airport would surely be a massive boon when it comes to competing for new routes.
For relatively modest investment, access to CWL could so easily be the airport's 'orange plane'.
