Bygones is the sixteenth episode of Season 3, and the thirty-fourth episode overall.
Edward can't shake the feeling he's been a little responsible for Alfred being sent away in 1923. He stops outside a signal box where he meets Thomas. Later, Thomas arrives at Knapford and tells Gordon about his account of the incident. He was shunting while Alfred passed him with his train. He saw some sleepers move, whistled a warning, but unfortunately Alfred didn't hear him.
Gordon is shocked and asks Thomas why he didn't bring this up earlier. Alfred, meanwhile, is travelling with a goods train when he derails at the crossover outside Killdane. Sean saw the accident and calls for help. Gordon is at Maron station when the stationmaster tells him what had happened. Gordon takes the train to a siding and comes back for Alfred.
The arguing is finally over when Gordon apologised to Alfred for the misconception. At Maron, Sir Topham Hatt says to Alfred that the railway inspectorate in London will re-open the case.
