This production starts by showing scenes of the lines under construction and the trams being built at the Alstom factory in LA Rochelle, France.
This is followed by a detailed look at the operation of both lines including visits to their respective depots.
The Red Line links Connolly and Heuston mainline stations, before heading out to Tallaght in the south west suburbs.
The Green Line terminates at St. Stephen's Green and, after traversing Harcourt Street and Adelaide Road, climbs onto the alignment of the former Harcourt Street to Shanganagh Junction railway line, to head southwards to Sandyford.
Both lines are operated by Alstom Citadis trams, the Red Line using 26 30m long type 301 cars, and the Green Line using 14 of the longer 40m class 401 cars.
