Description of the Great Northern Railway - 1800s

I came across a well written partial description of the line in working years from Highgate to the Alexandra Palace terminus:

‘On either side of Highgate Station were two sets of single-bore tunnels and the station itself was nestled under Archway Road. As it was originally intended as an intermediate terminus, the two platforms were built sufficiently far apart for a siding track between the platform lines. Increasing traffic lead to a rebuilding around 1880 when the side platforms were replaced with a central island. Access to it was gained from a booking office on the footbridge which led to entrances on both sides of the line. Most of the station is still unchanged, although the surface platform became disused with the withdrawal of the Alexandra Palace service and access to it from the circulating area was subsequently eliminated.

Leaving the junction the Palace branch curved east along the edge of Highgate Wood and entered Cranley Gardens Station. Its wooden booking office was on the west side of Muswell Hill Road and a footbridge led to the platforms with their wood and brick buildings. A separate pedestrian exit was also provided from the down platform to the corner of Muswell Hill road and Woodside Avenue. Here again, footpaths led to the station. (Nowadays housing occupies the station site whilst a school has been built in the former goods yard).

Muswell Hill Station was built next to The Green Man, the line then crossed a valley by a 7-arch viaduct (still over St James’s Lane) to circle around the north side of Highgate Woods and to join Highgate Station.

Under the road bridge the tracks gradually emerged from the cutting, and looking towards the ridge the line entered Muswell Hill Station. Very conveniently situated for the shopping centre it had a small forecourt off the bridge. The brick booking office had stairs leading to each platform but rush-hour travelers could use another entrance at Dukes Avenue. (Today a primary school uses both the station and the entrance from Dukes Avenue).

Onwards the branch ran mainly in a shallow cutting as the Palace loomed up on the right. Passing the signal box on the left, immediately the line ran into its terminus.’

I find the description very well written as I personally know The Parkland Walk as it is at present and have walked it many times and I can visually picture all of the described and how it would have been while it was fully running.
The description was found in book 'Rails to The Peoples Palace & The Parkland Walk' written by the Local Hornsey Historical Society.
