We all know the benefits to be had from keeping our model railway locomotives and rolling stock lubricated: smooth running, no squeaks, less wear on the gears and bearings, and potentially more reliable pickup of power from the wheels to the motor or decoder in locomotives.In damp environments, oil can provide some protection against corrosion of metal parts.But not everybody is aware that some oils can harm some types of paints and plastics used in model railways, and can be too heavy for use with the relatively delicate model railway gears and bearings.Woodland Scenics have come to the rescue and have formulated this oil especially for use in model railways, giving modellers peace of mind that the oil they are using is actually helping rather than harming the products it is applied to.The bottle contains 5 fl.Oz (15mL) and is fitted with an extra fine nozzle to permit accurate application into tight spaces.Recommended for small gearing found on Z to N gauge models.
