Within the first minute and a half of the film the locomotive pulling the Euston to Liverpool express varies several times in cut shots from the largest 4-6-2 "Duchess" express locomotive to a variety of different, smaller 4-6-0 locomotives, variously with or without smoke deflectors, with single or double chimneys, with tapered or parallel boilers and with different numbers and tender insignias ("British Railways" or "LMS"). At one point a "Duchess" is seen again. Locomotive classes seen pulling the same train without it stopping thus include "Duchess", "Jubilee", "Patriot" and "Royal Scot".
At 1:13 a clean, rebuilt "Royal Scot" class 4-6-0, number 46126, backs onto and couples up with the carriages forming the express in the station. At 1:14:52 the train leaves the station headed by a scruffy "Jubilee" class 4-6-0.
As the train approaches the level crossing where the crash takes place it is traveling through open countryside. Yet during the rescue operation after the crash a bridge is clearly visible at a point 30 to 40 meters behind the train.
