Project T1196 had the objective of delivering a suite of pantograph gauges that will allow simple application of Railway Group Standards, balancing complexity and gauge conservatism. This important research will support the design and delivery of electrification programmes as part of the ongoing decarbonisation of transport in the UK.
Well done to our team of authors David Johnson (D/Gauge Technical Director) Ian Johnston (Head of Engineering) and Jenni Willinson (Project Engineer). You can read the full report, Development of a Suite of Pantograph Gauges - Summary Report (T1196 Report), on the RSSB Spark Railway Knowledge Hub.
The introduction of Railway Group Standard GMRT2173 (Issue 3, 2019) and the European Standard BS EN 50367:20121 in recent years have introduced new complexity into the calculation of the swept envelope of a pantograph. Specifically, GMRT2173.
(Issue 3, 2019) prescribes the relationship between cant excess and deficiency and pantograph sway, and BS EN 50367:2012 prescribes the behaviour of pantographs with independently sprung heads. There is no single gauge or ruleset that allows the simple application of these standards.
The project aims to define a series of gauges to accommodate the parameters defined in these standards, balancing off complexity and gauge conservatism.
Specifically, this project has set out to:
