The overbridge was still there in the early 90's. The GCR was the Great Central Railway, and this was the 'London Extension' the last major main line built during the growth phase of the UK's rail network. It was seen/proposed as an alternative mainline route to those still extant fron Kings Cross (GNR), St Pancreas(MR) and Euston(LNWR). However the success of the other lines meant that it didn't achieve the critical mass required and was one of the lines cut of the Beeching era. The alignment of the route was as a high speed line and has been reconsidered for use for recent new north/south high speed lines.
The Brill tramway was like many rural branchlines long on charm and ambition, yet short of realistic economic potential. It was absorbed into the Metropolitan line (as per the underground), and closed mid 1930's.
