Presentation To Cherrywood Inquiry (Luas B1) Mark Gleeson BA BAI MSc MIEE Technical Officer Platform 11

Platform 11. Ireland National Rail Users Organisation Concerns Capacity Impact on existing passengers of Line B Design Road junctions Stop locations Route Choice Glencairn Vs Harcourt Street July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Platform 11. Ireland National Rail Users Organisation Capacity (1) Existing Line B classic Dublin low density Relatively static population Higher density development on Line B1 Glencairn Ballyogan Cherrywood July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Platform 11. Ireland National Rail Users Organisation Capacity (2) RPA approach Increasing frequency from every 5 to every 3 gives 67% increase Reliability with level crossings ? 40m to 50m gives 34% Possible impact on performance Depends on platform lengths Combined gives 123% Is that enough ?? Is there sufficient capacity for the Next 5 years? Next 10 years? Line B already ahead of forecasts July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Platform 11. Ireland National Rail Users Organisation Design - Clonlea Listed status could lead to delays Awkward CPO Legal challenges Could lead to an undue delay in the delivery of this project, with resultant impact on costs. In light of the ambitious targets laid down by Transport 21 this is of particular importance. Vertical alignment suggests possibility of cut & cover Glencairn stop is on a significant hill July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Platform 11. Ireland National Rail Users Organisation Design - Depot Access Still only one single track Red Cow, Fairview and Inchicore All at least 2 connections Best practice 2 derailments leading to disruption already July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Design - Road Junctions Many road crossings at or near T junctions in Ballyogan and Glencairn Reduced visibility Traffic management issues Traffic queuing blocks tram line Classic yellow box problem T junctions are the most tricky of all level crossings July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Design - Racecourse Stop Which racecourse ?? Stop name ambiguous Location is distant from Leopardstown Quicker + cheaper via Sandyford No local access provided Occasional status provides no local benefit July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Design - Emergency Crossovers No emergency crossovers on the proposed 7.6km alignment. Line B, which is of similar length has 2 At least one should be provided Later addition of a crossover may require permission of the Department of Transport. July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Platform 11. Ireland National Rail Users Organisation Route Choice Harcourt Street route More direct Fewer at grade crossings Minimal disruption during construction However smaller catchment area Glencairn route Significant catchment and demand Archeological issues More CPO July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Route - Sandyford - Central Park Selected alignment Alternative Continue on the Harcourt street alignment in parallel to the current depot to Brewery Road turn left and continue towards the Leopardstown roundabout July 15, 2019 Platform 11. Ireland National Rail Users Organisation

Route - Sandyford - Central Park Benefits Reduced land acquisition Provides full segregation Avoid Burton Hall Rd Awkward crossing FAAC electronics site Minimises disruption to existing Luas services during construction phase Provides access to depot from both north and south sides Maximises use of existing Harcourt Line July 15, 2019 Platform 11.
