[PRCo] NACHOD SIGNALS--TECHNICAL QUESTION

[rogertrolley.1 at juno.com]

I just reviewed an old accident (no location)in where a single track line had 2 miles between sidings. Car entered single track at location A and a car entered single track at location B at the same time. Car at location B changed ends and returned to dbl track thru signal trippers of NACHOD system. Question is ,did he trip signal to green on outbound side, even tho there still was a car in the single track block heading toward location B setting up a potential head-on collision?????   any takers??    cheers rogertrolley
