Due to issues with a Class 90, Caledonian Sleeper had
to use 87002 'Royal Sovereign' to work a northbound sleeper service on 23.06.15. This meant that the vintage AC electric was somewhat isolated out of position in Scotland and unable to undertake its ecs duties from Wembley to Euston. Rather than run it as a highly inefficient light engine operation it was utilised on the 1M16 up Highland Sleeper. After checking the internet I found that it was indeed leading the train so I popped out from home to see the train passing a rather grey Milton crossing between Roade and Blisworth. Notice that the 87 is in its smart new Caledonian Sleeper livery with branding but that the Mk. III stock is still in the old First Group livery who relinquished the franchise three months previously.
