The Kashmir Railway Project aims to provide reliable transportation to the Kashmir Valley by constructing a 345km railway line. It faces significant challenges due to operating in mountainous terrain with extreme weather conditions. Major obstacles include long tunnels, high bridges, and construction through seismic zones. The line is being built in sections, with the most difficult being the 148km Katra-Quazigund leg requiring a 1.3km bridge over the Chenab River that is 359m high. Construction began in 1994 but has faced delays, with the projected completion date now in 2020.
