The GWR announcement has been greeted as good news for Swansea - and it is, not only for current businesses but also for new ones and for the university - but industry, in particular Tata Steel, at intermediate points along the line will also be winners.
The timescale seems right, as well: naturally following on from the work already started. Too often in the past, there has been a big government investment in infrastructure projects followed by a retreat, leading to a break-up of construction teams and a waste of expertise. The only thing that concerns me is the future of the "bi-mode" electro-diesel train-sets (image above) scheduled to replace the HS125s on the Swansea run. The contract for these was still not signed in March of this year. One hopes that there will be no further dithering, because even after the electrification to Swansea there will be a need for them on to Llanelli, Carmarthen and Milford Haven.
All in all, a real triumph for the coalition government after years wasted under Labour. Liberal Democrats have always advocated a better balance between road and rail investment, and it seems that LibDem Norman Baker, as a minister in the Department of Transport, has played his part in the electrification decisions.
