Everyday is different
Was on the 13:00 from London Paddington to Bristol Temple Meads when we were routed into the loop at Challow and crawled along before coming to a stand. Seems we were carrying a mobile fitter who was dropped off to attend to a sickly 12:15 from London Paddington to Cardiff Central which was sitting on the Down Main. Never had that before. Not sure what was wrong with the Cardiff service or how long it took to fix. When I got out at Swindon the displays were showing the failed train was going to be terminated at Newport. By the time I got down the stairs it was being cut short at Bristol Parkway.
