Keala R. Kaanui, The emphasis on TOD is an tantamount to an admission that there is not enough housing along the rail line to justify it.  Housing along the rail line is sparse.  Much of it is open space, light industrial, commercial, and single-family homes.  There are a few low rise apartment buildings here and there, with some high rises in Kakaako, but much too few to create a potential customer base that is within easy walking distance of rail stations.
