There was once a link between the LNWR St Albans Branch just north of the new How Wood station, to the MR main line close to the site of Napsbury station and the branch to the former mental hospital. According to Wiki, it was built to allow materials to be delivered during MR construction but I know no more about it than that. The earthworks at the LNWR end are still clearly visible, but the rest must have been obliterated during the construction of Radlett aerodrome, probably in the 1930s.
