With only photographs of the bridge to hand the challenge is to accurately determine dimensions of it. First stop was the satellite image on Google maps and using the scale measure provided I estimated the length of a side to be 150 feet, that's 600 mm in 4 mm scale and since the sides are skewed the model is going to be huge. Next, I needed to work out its height and radius of the curved top.
My photo of the north side was opened in Photoshop and scaled by reference to the brick pillars and a standard brick size and as a check measured the length for comparison with the previously determined 600 mm. It was 601.5 mm - good enough.A Model Railway - Life in Miniature
Railway modelling is a craft that fuels the creative needs of the soul. This is a journal about my railway modelling activities.

Project 24 - Battledown Flyover #1 (preamble)
Having successfully completed my first Resin 3D print project I was considering what to create next. The thing about Resin 3D printing is its ability to produce miniscule, crisp details. This drives us to go the extra mile in model design. In particular, as far as railways are concerned - rivets. Yes, I have become a rivet counter!
Within walking distance of my home is Battledown Flyover - The Gateway to the West. It carries the up line from Southampton whilst the Salisbury up & down lines pass underneath, at a slew.

If I modelled this scene where could I put it? My railway room is overflowing with layouts.

Ballast Cleaning Train - Part 19 (SLA Resin 3d Print Version)
This is the final part for this project.
How they were coupled for travelling. In operation the generator was coupled to the other end of the machine and an electrical cable connected between them. |
