A really well scaled blend that accurately reflects prototype size and is eminently suitable for 4mm scale (OO) or HO modelling. The Club Tub is a real value pack for clubs or team-build layouts even those with larger layouts who want total consistency in their ballast supply or really good value! The Brown mix colour has been chosen based on field research and is suitable for heavily trafficked modern or lightly used Steam Era lines. This carefully processed Ballast should not change tone when glue is applied using a suitable mix and wetting agent.
