Unsure if they're being done in canton or not, but i saw what looked like 2 empty fgw 143's towards cardiff central, in the direction of canton
unless of course they're being use for Taunton > Cardiff
Could be on Taunton-Cardiff. They have been recently.
They are going to be refurbished aswell but I thought they were following 150's through and I doubt that
FGW▸ would put two out-of-service at once.
