Every year, thousands of pounds are spent in producing and installing new FSPs on the rail network. This was the case at Grangemouth Junction in 2017 where the normal method and route was being followed. Timescales and deadlines were driven by the installation and laying of new FGT 2 Core 95mm² Copper cable. A new iLECSYS DITA (Distribution Interface Transformer Assembly) was also installed at Grangemouth Junction midway down the new feeder. This allowed for the de-markation between the Fouldubs branch and Mainline. Following a successful training session with the iLECSYS Rail team, the decision was taken that the existing signalling location should be retained and that the only element that needed updating to Class II was the existing switchgear, terminals and transformers housed within.
iLECSYS proposed that following survey interrogation that all of the sites could be retrofitted saving on average of £8,000 per site. Due to a lot of the sites having multiple existing Legacy transformers, the decision was taken to use a quad output (4x350VA) transformer where possible. This would result in only having to install one transformer instead of three and maximise on space savings. This was also achievable due to existing low loadings on the transformers. This was particularly beneficial where more than one TX was present in the original LOC, why spend money on individual transformers when a multi winding TX can be utilised!
