Horsley railway station is on the NGL line between Effingham Junction and Clandon at 22m352y. It has 2 platforms which are adapted to manage 10 car trains. There are 2 main line running rails operating a mostly stopping service with interspersed fast trains. Platform 1 is 205m and platform 2 is 206m long according to the sectional appendix.

Much of the station platform area is served by high level tray work through the platform canopy and concourse area.

Fibre Joint F-2300-GSCS-A-02 @ 22m15y
Copper Joint C-2300-2301-A-04 @ 22m12y

NODE INTERCONNECTION OPTIONS
With both fibre and copper joints available off the up of platform 2 either cables could be routed. There has alternatively been identified a coppy joint behind platform 2 which would greatly reduce the cost of taking a possession to pull additional fibre cable.

...if interconnecting at the existing fibre joint
The joint is 192y on the up from platform 2 and there is tidy SCT (surface concrete troughing) as far as the survey would permit. The route from the end of the platform is troughing to the station building. There is also dig the complete length of the platform with pits.

...if interconnecting to the copper joint
The identified copper joint behind the platform is direct above troughing which runs to the station building. There is also dig the complete length of the platform with pits although it is not clear if there is a route from the troughing to the ducting.
