if you saw this on a model railway you would naturally assume that either the modeller was bone idle or had run out of weathering paint.
They do say truth is stranger than fiction and so’s the case here. This is a comparison of platform roads 8 and 9 in Leeds. 9, like most of the through roads at Leeds are primarily used by DMUs and show the evidence. 8 tends to be one of the 2 platforms reserved for the London service which is invariably (but not always) the electric Class 91 and Mk4s. The result is quite striking and would make an interesting talking point on a model.
