Note the 3rd rail pickup and <a href="https://en.wikipedia.org/wiki/Acton_Central_railway_station" class="extiw" title="en:Acton Central railway station">Acton</a> headboard. This stock was in use on the <a href="https://en.wikipedia.org/wiki/North_London_Line" class="extiw" title="en:North London Line">North London Line</a> -  ie Euston-Watford, Broad Street-Watford and Broad Street-Richmond services. This is an example of the LMS-built compartment stock, which tended to appear mostly on Watford services in the post-war period; Broad Street to Richmond was almost entirely operated by LNWR-built Oerlikon stock
