Were there ever such signal boxes?
If so, any information appreciated.

I have subsequently found the following response from Mikey under a different thread title 'Christmas Poser':

Regarding Twentieth Mile Up & Twentieth Mile Down s/boxes situated about midway between Hatfield and Welwyn North stations when those two boxes were built sometime during the 1870s or 1880s(?) I suspect the surrounding country side was mainly farmland until the current Welwyn Garden City was built and absorbed the area from the 1920s onwards.

I am not sure if both the Up & Down boxes closed at the same time but there is a picture in existents of Twentieth Mile Up box in circulation. Twentieth Mile Up box was situated in the deep cutting next to the Hatfield-Hertford single line roughly where nowadays the single line comes off the 'Welwyn flyover' and re-joins the current Up slow line just to the north of the tall Twentieth Mile bridge. I am not sure of the date of closure of either box (they may have both closed at the same time?) but I suspect that both boxes would have been gone by 1926 when Welwyn Garden City (box) at the station was opened.


So......to answer my own question...yes, these boxes did exist!
