Hi;
I happened to be listening to my scanner on the CSX River sub channel, in Teaneck NJ this afternoon.
A train (Q409) had just gone south on track 2 and was getting a crew change at CP3.
Q439 came south shortly afterwards, and received a restricting signal at CP10 S with the switch lined main to track 2.
Q439 contacted the NI dispatcher to find what his orders were. Dispatcher told him to hold at CP7 and that he would be following Q409 who was stopped at CP3.
A minute later Q439 toned up the dispatcher again to inform him that there was an obstruction at mp 8.8.
The dispatcher asked Q439 what sort of obstruction it was, and whether it could be removed by the crew.
Q439 replied that it was a simulated obstruction.
Trainmaster contacted Q439 to have him stop his train at mp 9.0.
Train came to a stop, and sat for about 10 minutes. Then trainmaster informed Q439 that the obstruction had been removed and he was clear of all track and equipment, and for the crew of Q439 to 'have a great day'.
Q439 then toned up NI again to let him know that the obstruction had been removed, and was given orders to proceed on track 2 to stop behind the Q409.
Being that I had never heard of a simulated obstruction, I Googled 'CSX Simulated Obstruction' and came up with this: http://www.utu851.org/Award%203.pdf" onclick="window.open(this.href);return false;
By the gist of this file, simulated obstructions are used to test the crew's response to obstructed switches, etc.
I'm curious about this now. Are simulated obstructions used frequently? And if so, why was this one at a point in the track where there is no switch. The Q439 had just crossed CP10 with a restricting signal, and the next switch is CP7, at about mp 7.8.
Also, did the restricting signal at CP10 have anything to do with the simulated obstruction? I would assume that it was set by the dispatcher, but I had thought it had something to do with the fact that there was another train stopped south of CP5, and the dispatcher wanted the Q439 to stop short of CP7 so as not to block any crossings. There are no crossings between New Bridge Road just north of CP10 and the pedestrian crossing at Fort Lee Road, about 0.25 mi north of CP7.
Thanks for any info.
