You can keep tabs on the SIRR/RVRR reactivation on the Morristown & Erie forum,
http://www.railroad.net/forums/viewforum.php?f=114.
In the meantime, the facts:
1. What used to be two separate lines, the Staten Island Railroad and the Rahway Valley Railroad, are being referred to by the Morristown & Erie as the "Rahway Valley Railroad." See
http://www.merail.com/rahway_valley_rr.htm
2. The M&E has run 1 (that's
1) test train on the former SIRR portion. Two photos can be found on the M&E's homepage,
http://www.merail.com/. The SIRR is not yet officially "reactivated."
3. The delay in putting the SIRR portion into regular service is, indeed, the wait for the DOT to replace old signals and install gates.
4. There is no indication that any signals or gates have been vandalized recently. These are still the old ones, which have not seen use in many years. It is not at all likely that the vandalism was part of "Stop the Train" efforts.
5. The RVRR portion has seen brush clearing, removal of old rail/ties/ballast, and even some installation of new rail/ties/ballast. That work is ongoing. All of this work is in Roselle Park, Kenilworth, and Union.
6. No work at all has been done in Springfield or Summit (except where an enterpising housepainter cleared a section of the ROW near Baltusrol Golf Course to sell parking for the just-completed PGA Championship).
