Cut and cover A tunnel or box structure where a trench is excavated to the required dimensions tunnel/box and is roofed over with an overhead support system , strong enough to carry the l oad of what is to be built above . Engineering A non - service track connection between two rail systems to allow movement of link vehicles between them for maintenance or for stabling in a depot. Track i nter - Where tracks are side - by - side, the track inter - axis is the distance between the axis centre points of each track. The wider the distance, the more space there is between passing vehicles. Tunnel p ortal The entrance or exit to a tunnel. The interface poin t between the underground tunnel and the ground level. Segregation Metro tracks are fully separated from other traffic and from pedestrians. It is an essential requirement for the running of high frequency m etro vehicles.

Therefore, t he objective of this Green Line Metro Upgrade study is to estimate the costs and identify the extent of work required to upgrade Line B from Ranelagh to Sandyford for three potential metro operating scenarios, namely: 1. Scenario 1: 60m long low - floor vehicles, operating similar to the current Luas system with minimal additional segregation with the exception of road junctions. 2. Scenario 2: 60m long high - floor vehicles, op erating fully automatic and requiring significant infrastructure segregation from road junctions, other vehicles, passengers and pedestrians . 3. Scenario 3: 90m long low - floor vehicles, operating similar to the current Luas system with minimal additional
