On Thur 13th Feb, a freight was routed via the avoider and blocked it whilst it waited for the delayed 1806 to go to Westbury and Frome. They then let the freight out to turn into Frome loop in front of the late running 1836 slow to Plymouth that was in Westbury. By this point we were right behind the freight on the bypass on the 1903 to Plymouth as we'd already pretty much caught up the 1806 and 1836. However, they held us to let the 1806 and freight go and then they let the 1836 go first too. So we both ended up late for absolutely no reason and they had to hold the Barnstaple and Penzance trains at Exeter for us. I think another reason it's happening more recently is the works at various times on the West of England line meaning more trains are reversing in Westbury taking up platforms the limited number of platforms.
