I'm caught up in this. I was on the 1936 LM service from Nuneaton to Euston. We were held at Rugby before proceeding to Milton Keynes where the train terminated. We were told to get on a Virgin train from Milton Keynes which has run on the slow lines practically all the way. Apparently this train turned round at MKC which I would have thought is quite unusual given it has made it through the disrupted area.
We crawled through Kings Langley on the slows. To the south of the station were two penldolinos, one on each fast line, with the front of the southbound one being inspected by several 'orange jackets'. Couldn't see much else due to it being dark.
Thoughts are with those involved.
