The viaduct track needs to accurately align with the track on the baseboard and that involved much discussion and preparation.
This layout is being developed to give members the opportunity to try out new techniques and learn new skills which they can re-use on their own layouts.
The layout is 4mm scale with two loops and a freight line. The layout can be controlled by analog DC controllers or by digital DCC control.
There are 20+ points on the layout and these are controlled by the CBUS messaging system developed by members of the Model Electronic Railway Group (MERG).
Each week a number of members get together to progress the layout and the postings below summarise what is being done.

A tale of Gorilla glue, five minute Epoxy glue and the ubiquitous PVA. All three glues needed to ensure that the track and viaduct components stay together. Apart from that work started on the station mimic panel and the modellers started stripping - the ballast that is.
All the components of the eight arcch viaduct have now been 3D printed and glued together. The 'ravine' has been made wider and the arches now lock in place. A line of low relief cottages is under construction. More progress on fiddle yard pointwork.
The 3D printer has been working overtime and four of the eight arches are now ready. Work continues on the wagon works, fiddle yard points, DC control wiring and servo movement detectors this week.
Purleigh members had the distraction of a weathering workshop and an electronics workshop to contend with but still managed to make good progress on the wagon works, pointwork, interchange interlocking and viaduct planning.
We have been doing some further thinking on the girder bridge and dcided that we needed to rethink our approach. Some early prints of a curved viaduct, using the new Prusa 3D printer look to be promising. Even more so when the height of the viaduct differs from the baseboard height …
The tracklaying focus ois now on the West side of the fiddle year. Three 3-way points were ripped up in preparation for the laying of conventional points. More work on electronics and a revamp of the mimic panels.
Sckets are being placed at four stations around the layout to allow flexibility in operation and to allow multiple operators to work in their own space without getting in the way of others. Multiple sockets are available for DC and DCC control.
