Some of them suffer from poor lighting, and some are blurred, but they can be (mostly) fixed with a better camera. The biggest issue is the composition, and that will take time and experience to get right, but you will improve.Perhaps the same points or different ones could be raised in these HST ones I took? (on the same day, also at York)
The confusing thing can be when shooting on curves (and even at some stations), the track can be slightly canted so the train won't look straight even when the horizon is!
Station shots can be really boring... unless some thought goes into them. It's better to take a smaller number of considered photos, than to just take loads of photos randomly.
I don't generally take station photos.
Consider the lighting, for example this photo benefited from the low glow from the sun (btw, I have no idea who the enthusiast at the other window is).
For station shots, consider night photos, perhaps a low down angle might work? (example) Keep the camera still to avoid blur.
I am not a photographer either, but from an enthusiasts point of view, I could not disagree more. I realise it is all personal preference, but station shots are my favourite. I love to see the trains in station settings, especially if they are in ones I have never visited.
