Chris Powers, a Cincinnati native, has spent the summer in Dublin using their LUAS streetcar system. Over on the CAAST blog, he explains how his experience in Ireland has convinced him a streetcar will be successful in Cincinnati:
One of the primary reasons that the street car has been pushed is its role in helping re-develop the rougher parts of cincy that it runs through including Over The Rhine. A similar idea was apart of the planning of the LUAS as it runs right through the north side of Dublin where many underdeveloped areas have historically been located. The LUAS since its installation has brought a significant amount of new development to the streets it runs through including a lot of tourist development.
