The ballasting method was tested. A mix of 50/50 PVA glue (with a drop of detergent added) was applied between the sleepers and ballast spinkled on. The ballast used was from Woodland Scenics. It was allowed to dry and excess ballast removed with a small vacuum cleaner. From the trial the mixed version of grey and brown appeared better than the pure brown. Just using the grey would have looked out of place and was not tried.
