A centerpiece of the new Blea Moor layout is a T gauge model of Ribblehead viaduct. This is a 3D printed model, 0.9m in length, designed in pieces using OpenSCAD. While not totally accurate, it does capture most of the prototype's distinctive features.
After a few more experiments, it turns out to be very easy to convert this free data to a 3d printable terrain model, as well as to cutout diagrams for foam sheets representing selected contours for scenery construction.
One challenge With a layout like Blea Moor is getting the very well-known terrain just right. Contour maps are the obvious source of data, but there is a UK government website with free-to-download 1m and 2m resolution aerial LIDAR (laser-radar) data covering much of the UK.
The picture shows the north end of the Ribblehead viaduct approaching Blea Moor, plotted in Excel. This has potential, so more to come! https://environment.data.gov.uk/ds/survey/index.jsp#/survey The baseboards for Blea Moor have now been built, as an arc of 4 boards following the 1-mile radius curve of the track in this area. Viewing is from the outside of the curve, with an outside length of 6.5m or 21.5 feet.
I have been planning to start building a new exhibition layout for over a year now, but have found it very hard to decide what to model.
I eventually settled on the Blea Moor to Ribblehead section of the famous Settle and Carlisle line, done to about 90% of true scale. |
