ABOUT SOUTHAMPTON AIRPORT PARKWAY RAILWAY STATION
Hastings station is sat at the conjunction of the TTH and ATH lines. The station is a combination of a relatively new build station concourse and overbridge between platforms, of older construction.  Platform I is a bay platform facing the up ATH direction, platform 2 (Down Ore Up Hastings) and 3 (Down Hastings/Up Ore) serving as up and down ATH lines, platform 4 line is referred to as the Number 4 road, and appears to act as a platform for turning trains round, or as an overflow for the other main platforms.

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

The current SISS equipment room is located to the rear of the new station building, adjacent to the plant room. The SISS equipment rack is co-located with the station fire suppression system and two boilers so some consideration may be required regarding situating equipment in this environment, although it is unlikely to go to the lower end of the temperature scale of the equipment operating parameters. The room is lockable and keys are retained by the TOCs station staff. As far as a suitable location for the network terminating point is concerned, it is possible to locate a lockable Network Rail equipment rack. A few elements in the room currently are redundant so some degree of rationalisation can be undertaken to free up space.  Additionally, station staff use the room as a bit of a property lock up, which may require discussion also.

Station SISS wise the station has a mix of CRTs and ANDUs on the respective platforms; situated predominantly at the foot of the overbridge stairs, and portrait LEDs in the station concourse.  It is anticipated that the TOC will want to relocate the platform displays as they create a bottleneck at the bottom of the stairs.

Depending upon TOC requirements arising expect this to be a Cat B or C station CCTV, SISS and public address requirements.

The station has been rebuilt in recent times so it may be that the TOC will want to offer additional services to the customers e.g. WI-FI. Power at the station is apparently in good condition with a number of spare ways available.

That the node is within reach of the station a diverse route may be possible but a few issues to overcome as outlined above.

Surface concrete trough (SCT) cable route exists to the rear of platform 4 on the opposite side of the station to the station building and hence equipment room. A short section of SCT is in the up cess prior to the road rail access to the up end of the station after the old p-way accommodation, but this doesn’t interconnect to any other sections of route.

ACCESS/EGRESS
Via Authorised Walking Route – 82 MP + 528 yds, via Park sidings

NEAREST NODE/JUNCTION
2235 Hastings 82m291y actually shown as 82+201may be behind signal box in park sidings check again.
The original node location mileages were inaccurate the node is adjacent to park sidings at ATH 82.15 approx or TTH 62.52. The authorised walking route is correct as the access point; this is the signallers access to the signal box from park sidings.

NEAREST JOINT
F-ADIC-BPJC-A-32 - Node section 2236-2235  (ADIC-BPJC)
Location OS ref 581197/109595 - TTH 62MP + 394m Up Hastings

NODE INTERCONNECTION OPTIONS
The nearest node (Hastings station node 2235) which is supposedly at 82m201y according to asset data, as built records photos put it behind the signal box in the sidings adjacent to the station, this required re-checking and was located at approximately 82+330y.
On the approach to Hastings tunnel, is the nearest fibre cable joint that is not directly associated with the node itself.

...if interconnecting to the node
Utilise equipment room trunking to exit the SISS equipment room at high level to the concourse area, identify or install interconnection via the platform approach area to the down cess adjacent to platform 1 where this an S&T route travelling in the down TTH/Up ATH direction towards the signal box and ORE. Approximately 250 yards in this direction is a UTX to the opposite cess, utilise this for interconnection to the opposite cess (UP ATH/DN TTH). Investigation is required into the function of the route in the opposite cess if E&P install new route for 180m approx to the location of node 2235 in the UP ATH cess behind park sidings. Interconnect at the respective ODF.

...if interconnecting at the fibre joint
The joint is in the up cess on approach to the tunnel, approximately 70 yards Hastings side of the tunnel, hence the first route would be via station trunking through the wall from the equipment room and ticket office to high level trunking to the station overbridge which has high level tray to and down along platform 3 and 4. Currently there is no clear duct route from the platform to the down side trough route, so it should be assumed that a new ducted route will be required from the platform to the down side cess to interconnect to the down side route and from there the run to the sidings of 200m or so to the node.

The second and alternative route would be to locate the duct route from the equipment room to the car park (the alternative to this is to use the tray into the plant room and use the plant ducting out to the car park route) then from the car park route towards the gated entrance of the old p-way accommodation. From behind the gate, new duct route to the fence line behind platform 2 and SCT to the Road rail access point on the opposite side of the rail over road bridge and continue towards the Hastings tunnel portal, locate the fibre joint above.

The signal box is at the down end of platform 4, the FTN node (2235) is approximately 250m in the Up Ore direction in the up cess adjacent to Park Sidings. No obvious UTX in evidence between platform 4 and the up Ore cess but the station signalling services must get across to the signal box, so there will be something in the vicinity but local knowledge will be required to nail this element down if diversity is sought at this end of the station.

** RISK MATRIX CHECKLIST	NOTES & RISKS
Equipment room suitable for node	The existing SISS equipment is in the ticket office, there is very little room here, suggest replace smaller floor mounted rack with 2 metre rack and re-locate existing equipment.
Internal/external housing required	Internal
Station trunking suitable	Some supplementary work required to interconnect to routes toward the node.
External ducting segregated	Trunking within the subway looks to be segregated , under platform ducting needs inspecting, this was a non-intrusive survey so no cable chambers were inspected, these exist along platform 2.
External ducting clear/roped/accessible	Unknown but all trunking is in reasonable condition, assume rodding and roping will be required for ducts under platform 2.
Power supply suitable	Within the ticket office there is a distribution board which appears to serve existing small SISS equipment racks, there are four spare ways.
ET&I records obtained	Within main power room there is a record folder.
Power supply residual issues from ET&I	Unlikely but subject to ET&I documentation
Vandalism issues	None advised by TOC.
SSSI issues	None advised by TOC.
Other environmental issues e.g. rodents	None advised by TOC.
Existing support structures suitable	SISS equipment utilise standard fixings.
Existing guttering and drainage suitable	No drainage issues evident.
Listed building / heritage issues	None advised by TOC.
Noise abatement issues	None advised by TOC.
Pedflow and changes of function	None advised by TOC.
Issues left behind by previous projects	None advised by TOC.
Issues with exit from station to lineside	Route exists under length of platform 2 to line side east and west.
Any local issues, affecting subsequent work	Sizeable car park at station, Parking is metered and monitored agreement with TOC required for works parking.

SUMMARY
For the purposes of maintenance, and what would look to be a less problematic cable run, look to interconnect at the node ODF, adjacent to park sidings.
