It would seem that 1F45 the 1336 Birmingham to Liverpool lost it's pantograph on the approach to Crewe today. My question is this: why did this disrupt services which should not have been affected? Case in point woudl be 1T40 the 1405 Chester to Shrewsbury. This is a non-electric service routed via Platform 12 - as near as possible to a self-contained route away from the main line. Any thoughts?
