TD Joe Costello said the plan has now "morphed into a cross city metro line".
The metro project is due to start in 2021 and be completed in 2027.
Commenting on the newly published plans he said: "Now, inexplicably the optimal route of 2005 has changed from Drumcondra to the new optimal route of Glasnevin. In the process the price tag has increased by an extra billion euro to over €3billion.
"The changed route is creating a whole new set of problems. Some 100 houses, including over 20 in Glasnevin, will have to be demolished along the route to make way for the metro. Furthermore, a major GAA club, Na Fianna and a major soccer club, Home Farm, will have their grounds ravaged by the metro developments.

"For example, most of Na Fianna club grounds and pitches will be appropriated for the development for up to six years to facilitate the construction of the new Griffith Park station and it is not clear what will happen to the Na Fianna lands after the construction phase.
"Thousands of young men, women and children will be deprived of their sporting facilities and the immediate future of the club will be placed in jeopardy.
"To compound the situation the National Transport Authority (NTA) and TII conducted all their planning in complete secrecy only now opening up the consultation process after the major decisions have been made. Na Fianna were kept completely in the dark in relation to the drastic plans for their grounds and pitches.
"It is totally unacceptable for any state body to deprive this city centre club of its sporting facilities and the essential services it provides to the local community and beyond."
