Word just filtering in - I will elaborate in a few hours after sleep - of additional strikes on First Great Western, including around the August Bank Holiday.
The last one was pretty solid and brought travel on that line to a halt.
Affected will be lines out of Paddington including those to Windsor and Bath and Cornwall, among many others.
Elaboration as promised:
The dates announced are four, - Sunday 23 and between Saturday 29 and Monday 31 August.
Often days either side have knock on impact.
