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.
When Ron is let out of the locked fish van he asks where he's at and is told Macclesfield but the credits list the worker as a Lancashire railway man.
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.
As the train hits the tanker a shot of Jack Warner on the footplate shows him being thrown backwards but the impact would throw him forward.
At around 7.15 minutes into the film in the Hardcastle's kitchen you can see locomotive pictures on the walls, one of which is a LNER P2 in its original condition, why would a LMS/LMR driver have such an image? The shunting locomotive 47327 "Old Lizzie" was built in 1926, the same year as the General Strike and just as modern as the Royal Scot Class Hardcastle refers to. Lastly why would the fish van that Ron was put in be a locomotive yard?Still a great film.
In the shot of the train approaching the wrecked tanker there's just two main lines but in the shot of the carriages piling up there's a spur line going to the right.
