Here is John Thacker in a comment on my post Slow Speed Rail and the Infrastructure Deficit:
…consider the Southeast High Speed Rail Corridor. That’s mostly an upgrade of existing lines, combined with acquiring an abandoned line and rebuilding it. The environmental and planning work along has taken decades. The corridor was designated in 1992. The Tier I Environmental Impact Statement (EIS) was begun in 1999. That was completed in 2002, and received a Record of Decision. That cleared the way for the Tier II EIS, which began in 2003. The Draft Tier II EIS was finished in 2010 and signed then. That cleared the way for the Final Tier II EIS, which is expected to be finished by the states by the end of 2012, and then a Record of Decision from the FRA by the Fall of 2013.
