Rugby and Crewe stops I think in addition to those mentioned above.

Your visual system gets conflicting evidence due to the fixed timebase video sampling of the image and the varying speed of the train. The most regular part of the view is the OHL posts, and the sampling rate / train speed combination determines whether these are perceived as advancing or retreating. (Same effect as spoked wheels 'coming to rest' then changing direction on film as their velocity increases.) When most of the other visual cues are lost due to fog your brain is pretty much wholy dependent on the OHL posts, and bases its' motion estimate on the artefact of the sampling timebase and velocity product.

The 'wandering all around the houses route' is interesting as a permanent reminder of the original concept, of picking up traffic from every place feasible en-route between the end destinations. The advance in speed in 1830 from horse and carriage or canal boat, to the truly startling 30 to 40mph of even the relatively early railway, must have made the relatively small deviations from the most direct route permitted by the geography seemingly inconsequential. A steam version of the trip would be a wonder, but we have to make do with the little we have. Recent BBC programming has shown a delightful clip of a Claughton overfilling the tender tank and giving the leading coach an impromptu wash, quite early in the LMS regime.

Great illusion isn't it? There's probably only one name on the tyre, but four, five, or more apparently identical spokes so they are effectively running at different frequencies. If each spoke was a different colour, then you would perceive them staying in phase with the the tyre makers name.
