Posted by Jackson Park B Train on Sun Apr 20 15:34:39 2014, in response to Commuter Rail - Help a Fiction Writer Get the Technical Facts Right, posted by Green over Green on Sun Apr 20 14:34:52 2014. Q 1 depends on the RR. For instance on Metra Electric on the South Chicago Branch, there are separate signals for the T/O showing the gates immediately beyond the station have deployed--can't leave the station until the signal allows. Thus the still open gates would be several blocks down the line.Q 2 In areas w/ multiple closely spaced grade crossings MAS is low. |
