Model Railway - TPWS Grids 3D print model

Train Protection and Warning System Grids There are two versions available single and double, they are also commonly found on railways in pairs.

These items have been designed to fit Peco Code 75 and Code 100 tracks. These are relatively small and thin objects so take care when printing and trimming.

Models are designed for OO/HO gauge track, approx 1/76 scale but can easily be scaled for other gauges. for O gauge UK at 175%, 1/43.5 Scale, for O gauge International print at 158%, 1/48 Scale, for N gauge print at 51.49%, 1/148 Scale, (Caution: I have not printed this model in N gauge so can’t guarantee their printability) As these have been designed at HO/OO scale when printing for other gauges you might have to experiment to get the size correct.

The examples in the pictures were printed on an AnyCubic Proton 3D resin printer. I recommend printing these on a 3D resin printer to get the best print definition. As normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.

The main resins I use for printing can be found with my affiliated links below. I use AnyCubic Water Washable Resin for most of my items but use AnyCubic ABS Like Resin for anything that needs to be stronger and tougher.
