The Cathcart Circle is an 8km long, circular track around the South of Glasgow, Scotland. Several substantial claims for compensation from the Scottish Railways had been submitted for wheel wear and complaints about the noise.
Cathcart Circle had 29 hydraulic and mechanical lubricators positioned trackside that were filled with an alternative gauge face grease. Engineers reported that even with a high quantity of lubricators, the grease struggled to carry down far enough lubricate all of the track. This resulted in noise complaints from the community and noticeable levels of wheel wear.
RS Clare were invited to trial their Network Rail approved Claretech Supreme rail grease and before the trial commenced 2 x LB Foster Electric Protector IV Lubricators and 1 x LB Foster Electric Protector IV Lubricator were installed along with 4 of the original hydraulic lubricators, and all of the remaining 25 hydraulic and mechanical lubricators were removed.
One of the key performance criteria’s for the trial was carry down distance and the engineer reported that Claretech Supreme achieved excellent bi-directional carry down, giving a plentiful band of protective lubricant. From the outset of the trial noise complaints subsided, and the wheel/rail wear reported has reduced considerably.
The Head Engineer at the Glasgow Maintenance depot has since converted the grease supply for all of their over 300 lubricators to Claretech Supreme, and their
lubrication maintenance team continue to feedback good performance, noting an additional tangible benefit that Supreme is cleaner to work with.
