50049 Defiance & 50007 Hercules cross Arten Gill Viaduct on 14 April 2018 with the Pathfinder Tours 1Z50 06:01 Birmingham International to Carlisle 'Cumbrian Hoovers' railtour. This was well worth the ridiculously early start, long drive, and then strenuous climb to get to this location. Given the rarity of Class 50s on the Settle to Carlisle line, I was surprised that there were just five photographers at this spot, which is one of the best viewpoints on the route. Admittedly there are many other scenic locations on the line, and some are easier to get to!
