Gwnaeth Trafnidiaeth Cymru ystyried nifer o fannau posib, gan gynnwys pen draw canghennau Leiniau'r Cymoedd, ar gyfer y depo newydd a chyfleusterau eraill. Er mai Ffynnon Taf oedd y lleoliad oedd yn cynnig y fargen orau inni o bell ffordd o ran costau cyfalaf a rhedeg ac arbedion, rydyn ni'n buddsoddi mewn cyfleusterau pwysig ym mhob rhan o'r rhwydwaith.
Transport for Wales considered a number of potential locations, including the tops of the Valley Lines branches, for the new depot and other facilities.  Whilst Taffs Well is the best value solution for the new depot by a significant margin in terms of capital and operations costs, as well as operational efficiencies, we are investing in other important support facilities around the network.
