Dovetail seem quiet about it but maybe I've missed an official announcement, anyway there are two computers currently set up in the hall of King's Cross station loaded with the London-Peterborough route and the Flying Scotsman. It's part of the centenary of that loco, and the 170th anniversary of the station, and there are other related attractions including the train itself steaming away on platform 1. Worth a look if you're in town, I think it's there until Wednesday!
