The latest Railfan Railroad Mag . says that the under river line to new
Pittsburgh Stadium will probably be a tunnel bore under the river
instead of a casson type drop in sectional tube due to the fears that
sediment stirred up will be heavily polluted with heavy metal toxic junk
from up-stream industries that used to dump their crap into the river !
A more costly way to get things done here !
