I created these cable troughs to lay alongside the track on my 7mm/ft or 1/43 scale O gauge model railway. These are a common sight all across the railway network carrying essential cables for signals and other systems.

There are files with lengths of 1 to 8 trough sections and each section represents a length of 1m on the real railway.

I have also created a set of closed troughs with the lids already fixed in place that can be combined with these open troughs just like on the real railway. They can be downloaded separately here:
