Delay to 1925 Docklands M3 Parkway
Not sure what is going on. When I arrived there was a 22k out of service and a 29k in service. At 1925 the 22k left empty. Driver of 29k is telling us that due to a technical fault on the train a replacement _will_ be arriving on the other platform and we are to change to that train. Still waiting for that to happen...
