'Duchess of Sutherland' is passing Harringay on Friday morning with the first leg of a nine-day tour round the island, the Great Britain XIV (details here).
What time? Goodness, don't know.
Neither the Railway Touring Company nor the usual online train time sources have posted any times as of 1900 Wed 20 April, just 36 hours before the likely off.
I'll carry on checking for times and put up a fresh discussion when I find them. It's not the MI5-grade 'Flying Scotsman' this time. In 2017 it was 0745, in 2018 it was 0825. (In 2019 it started at Paddington and in 2020/21 it, well, didn't happen).
For any very early commuters, it will arrive at Harringay from Southall about an hour earlier than whenever and then be towed in reverse to King's Cross.
