The last picture in the above series is an example of where with a little bit of extra effort they could have achieved a step-free pedestrian (/cyle) crossing, of course a bonus also for the elderly, those with buggies and the disabled. Insted there's ~12 steps on either side where to my eye there's plenty of clearance for ramps (particularly if the bridge was "humped" rather than flat.
Good pictures on the Railbrit site too e.g. http://www.railbrit.co.uk/imageenlarge/imagecomplete.php?id=48779
