Would like to see the routing from, right at Mangotsfield to Yatton, my suggestion, without a reversal, Mangotsfield to Gloucester, thence towards Newport taking the curve at Maindee East to join the Welsh Marches line to Hereford thence through Great Malvern to Worcester, Cheltenham and Yate taking the original GWR▸ curve to join the South Wales Main Line at Westerleigh Junction to Stoke Gifford taking the line to Filton Abbey Wood to Temple Meads and thence to Yatton.
Mornington Crescent!
