In Chapter 16, Strike arrives home from Cornwall via the “Night Riviera” sleeper train at Paddington Station.
If you’d like to see what Strike’s sleeper compartment looked like, check out this great video guide below. (Please note that the compartments were refurbished in 2018 so this is a slightly updated version.)
“Brinel’s steel arches curving above him like the ribs of a blue whale’s skeleton, cold dark sky visible through the glass ceiling.” Troubled Blood, Chapter 16
Strike also uses Paddington Station when he returns to Cornwall in Chapter 54.
