Many of the railway scenes in the movie were shot on a preserved railway line between Dendermonde and Puurs, Belgium.
The poem Thomas reads when he is with Evelyne, "I often make that strange and penetrating dream / Of an unknown woman and whom I love and who loves me ...", is "Mon rêve familier" by Paul Verlaine.
The lines after the fight on the train, "Out, out, brief candle! / Life's but a walking shadow, a poor player....", are from 'Macbeth' Act 5 Scene 5.
As some of the locations were rather remote (particularly the unguarded railway crossing at Sint Amands), much of the technical crew and equipment was carried on the train.
