I recently decided to try out Woodlands Scenics' track bed for a prospective OO layout (my first) - so having boned up on ballasting, I thought it only sensible to have a few test runs and see what worked for me...
Mixed results - but my main issue is getting the ballast to follow the steepness of the chamfer - I end up with either bald patches where the ballast has just fallen away, or a spread at a shallower angle that results in the ballast bed being too wide.
Currently thinking of trying options of removing the chamfer on the track bed / cutting the track bed to the sleeper width, and applying neat PVA to the chamfer before ballasting in the usual way.
But thought I might first ask if anyone has any tips for this?
