Superstructure
 

The railway is built on a wooden structure which is raised between 1 meter and 1.5 meters from the ground.

This structure is built from a mixture of 100mm (4in), 150mm (6in), or 200mm (8in) wide,  x 50mm (2in) high, tannanlised and treated carcassing, mounted on top of 100mm (4in) treated fence posts, which are isolated by being set in 375mm (15in) of 'Postcrete'. This in turn is covered with 12mm Marine Plywood, on top of which a layer of 'Green' Roofing Felt has been applied. - Side-Finishing has been added using redundant lengths of treated 100mm tongued and grooved section.

The Jetty Section is different in that it has been built using 150mm (6in) x 18mm (5/8in) planed timber, painted with several coats each of undercoat and external stonewall paint.
 
 
     

Stage 1 of construction at Coolamusta Mine:

100mm Fence Posts with 'Tee' pieces are set into 375mm of 'Postcrete and then treated with creosote substitute -

It is imperative that the timber does not in any way come into contact with the earth, because if it does, then the former will rapidly turn into the latter........

  

Stage 2 of construction at Coolamusta Mine:

Tanalised 'Cascasing' is laid and secured on to top of the 'Tee' pieces, before also being treated with creosote substitute
     
 
     

Stage 3 of construction at Harrison Point:

12mm Marine Plywood is laid and secured to the 'Carcasing' - The Jetty section has yet to be added

  

Final Stage of construction at Coolamusta Mine:

Green roofing felt is laid over the plywood and secured on the sides, over which strips of T&G are secured before also being treated with creosote substitute.

Trackwork
 
 

This has been kept as simple as possible!

Apart from the diamond crossings at the Coolamusta Mine and Harrison Point Yards, all track and point-work is ‘PECO’ SM-32. – The diamond crossings are both hand-made using components supplied by ‘Marcway’ of Sheffield.

To keep things even simpler, all points are hand worked, and can safely be ‘run-through’ by trains when running in the trailing direction.

All reference distances (or meterages) are measured in decimetres, the zero point being directly under the centre of the lighthouse on the end of the jetty at Harrison Point.

A General Plan of the railway (not to scale) is shown below:
 
 
The first ‘Visitor’

No sooner was the final fishplate fitted on the ‘Company's’ new railway on Anglesey did the first 'Visitor' turn up........... from the Planning Department at the Local Council!........  It would seem that not everyone in our hamlet was happy about the construction work that had been taking place, and someone had deemed fit to go sneaking!

Needless to say, the Inspector was highly amused and told the 'CSM Management' that it 'was the most bizzare complaint that they ever had to deal with'.

After the laughter had died down, a set of photographs were taken so that other members of the Planning Department could have a good laugh later, after which it was mutually agreed that there were some extremely sad individuals out there! - The 'CSM Management' are now in possession of a 'Certificate' to say that no further action is required!.............
